    The difficulty up here in the tropics is moisture, I will solder the joints and if I can find it use heat shrink with resin inside, guess I am just trying to make it as fool proof as possible as I don't mind fixing things but hate re-fixing because I overlooked something or was plain lazy.

Well today I finished off the re-make of the flying leads, took a pic of the rotor while it was out.



Some pics of the finished job.....




Mounted it back to the motor and started it up, meter across terminals, very low volts  ??? then I remembered bj's advice so a quick flick of the throttle and away we went, I suspect this idiosyncrasy has more to do with rotor demagnetization than deign.

So off and running I tidied up the controls somewhat....


 

OK I never claimed to be the tidiest person around but it works, lots to do yet but it works, the little Lister is happy at 1.5Kw so that will do me.

Hi Allan.....Looks pretty tidy to me :) Just out of curiousity what did you end up using on your connections?
Also are you working on any kind of system to make use of all that water?......artv

"I suspect this idiosyncrasy has more to do with rotor demagnetization than deign."

I think also you need to get near the "Q" of the circuit of the caps and excitation field to get it going also. It is frequency dependent to some extent as the caps and exciter windings like to be near resonance to fire up...... just as I understand it.

If the rotor is demagnitized, usually a quick splat with a 12v battery will fix it.

         I ended up finding some heat shrink tubing that has the resin on the inside, so that alone makes a water proof join over the soldered wires, over all of that I lacquered it with a two part "varnish" that I was using on wind turbine blades, it dries as hard as the hobs of hell, I don't know its heat capabilities but time will tell.

To date I have not done anything about hydro, I need to go through a whole season to understand the resource the creek presents and if I in fact need enough extra power to justify the expense. Many over here have installed hydro in similar creeks only to have it washed out to sea during a flood, I am currently helping two other with small hydro installs albeit both have good heads so all in all am keeping my hand in .

           This is a new alternator but I did test the caps and they were close to their 15Uf by my meter ( I know my meter reads a little low, quality Chinese unit), I had tried others before stripping but to no avail, but yes it is definitely something to watch in future, and it is definitely frequency dependent until voltage rises. A couple of friends dropped around this afternoon while I was testing this beast, in discussion I commented on the fact that this is a popular unit over here and maybe there were others with bad connections, " I have one that just stopped working " came the reply so tomorrow he will drop it off and time will tell.

Allan;
What did you finally do about the varnish? My grandpa used to make his own using pine tar or even creosote cut with turpentine.
He used iodine in it for color and stabilizer ( very little ) to re-coat his axe handles.
I used to use it when we re-wound old Chevy generators, before they came out with Alts, I can't remember them ever having a high-temp melting problem.

Hope that helps

This is an update on my as found on purchase Lister ST1 with belt coupled generator.

When I first viewed this property the agent was unable to start this generator because of what appeared to be a flat battery, this also meant we were unable to test pump the water bore. Anyway after deciding on this property I commissioned the area RE guy (who subsequently installed my solar) to test this engine and the bore when he was next over here, this  was done to my satisfaction.

Now since taking ownership the generator has occasionally failed to start, despite another battery, usually some strong words and clouts with a metal object seen it start. I some time ago removed the starter motor and deduced it was the solenoid, so I ordered one off the area specialist who dully delivered it, now I failed to pick up on his comment "was I sure it was the solenoid as I have recently fitted a second hand one".

However once I fitted the new solenoid it worked fine, for a while, then fell back into it's old habits, so today being the allotted day to remove the starter motor and give it a severe talking too, I did so. I had this theory that at some stage it had been dismantled and a washer left out because when I turned the motor via the flywheel one could hear the ring gear slightly rubbing on the starter motor pinion.

OK so part of my  duties was to fit a washer, I may add here that the commutator is a little unusual to me in so much as it is like a washer on the non drive end (unable to remember the technical term), so this fitted with my theory of a missing thrust washer as with one the brushes would be brought closer to the commutator.




OK I skimmed the commutator by putting the shaft in the electric drill and applying a file to the surface, finishing off with some fine emery, yes I know rough but it works.

Now in my quest to track this fault down I even went as far as dismantling the new solenoid to check the contacts, that involved unsoldering the end, all to no avail.


So the end result was loose connections where the earth brushes connect to their flying leads, see the uninsulated leads in pic one, so a bit of brute force and some 5 min Araldite it was "fixed" for now. I contacted the agent who will bring a new brush set over when he is next over here, this is actually the whole end plate.

So to replace the starter motor..






As an extra to this post, my northern neighbor  has a small petrol generator which he runs all day, much of the time unloaded, he has batteries and an inverter but lacks the knowledge to schedule charging.



Now his generator is quit close to his house but this does not seem to bother them, but it does me.



They are away at this point in time, but upon their return, they have agreed to get together and move the blo**y thing to the other side of his house, because his northern neighbor does not live there but I assume stays occasionally. 


]

That neighbors panels.

A funny (to me ) thing happened to one of the dogs on the way to this persons place, Bandit found out what Lawyer vine is, so named because once it gets it's hooks into you you are stuck.



But one thing I did discover was where the creek that runs in front of my block and the one that runs behind join,


This is little Fairy creek just before it joins Fairy creek again.



Just a couple of extra pics.

The above mentioned motor/generator set does quite well on fuel, a recent test revealed 0.39 Liters/KWh, now with fuel here running at around A$1.60/ Liter the cost after Government tax of 38C/l is 48 cents/ KWH, not too shabby actually. ( I get the tax back because there is no mains power here)

Talking to the area Lister specialist today he informed me he installed this unit about 9 years ago after overhauling it, well he did a good job because it runs sweet. I do not know it's true age but Lister's just keep on keeping on.

As opposed to this unit the Little Lister LT1 I recently posted about returns around 0.78L/KWH @ 1KW load, now here it is fair to say this motor has not been overhauled, I do not know it's history, and the gearing is less than ideal. Despite all this it will be a good back up to the back up if it all goes pear shaped. Once I have lived through a wet season and have the LCD telly working as opposed to the plasma I will be in a better position to know if I should spend $$$$$ on this unit. Just waiting on the roo mail to deliver an expensive($12.50) mini amplifier from China (the LCD telly has lost sound but I can take the audio straight from the satalight box)

You have not heard about roo mail....http://www.youtube.com/watch?v=ndnUTM57iqg sometimes a bit slow, but hey mostly we get mail twice a week.

Loved the video, Allan!

You folks underneath there sure have some "interesting"  ways! :) ;D

We tried that with deer here but you never get them to stand still the second time you try to stuff the mail up their arse!

I guess the pouch makes it work!

Allan of the jungle, buggered after walking up a creek, twice helping a mate with his hydro and no we did not have a paddle, so some may say we were up the creek without a paddle.

PS. when I get the pics loaded I will post any that are worth posting, I was using his water proof camera so I am not sure how many I took are any good. ;D

Today's fun was checking on a mates hydro to be pipe, it runs about 600 M up a creek to a hole above a water fall which can stand the 2" pipe at our current estimate 2-3 L/s.



The pipe then travels down the second water fall....



Just below this we re-aligned the pipe to be out of the creek because big bolders get washed down in the wet season and damage the pipe, so this was the flow at the point of re-joining, that mountain man is a bit scarey to me, I had my backside on a rock.



The passage up the creek.

BJ I believe it is Northern Olive AKA Native Olive, grows into a tree, many Australian native plants feature purple flowers/fruit.

OK take two on my pics, this is just flowers in Blondie's garden










And yes we have bananas



Chillies anyone



This cucumber vine is on its second crop



Beans, I enjoy growing plants the "locals" tell me I can't


I am still in awe of the front creek, still thinking hydro




But then it rains



Funny thing up here, the jungle comes alive in spring (like most places) but it gets sticky (humid) and it rains, yes it rains in the rain forest, but for about two months the tourists stop coming, and miss all the beauty of spring. Fair enough after heavy rain they may be stranded at a crossing or two but the creeks recede as fast as they rise so a couple of hours parked enjoying the scenery should not be that hard.

This program hates me it wants to double up, bar humbug, oh and don't tell anybody I have been photographing flowers now will you!

just depress everyone.  Like everywhere, (almost)  it gets right pretty in the spring.

Once again not realy anything to do with renewable energy, oh one pic has solar panels, but highlighting the jungle. I went to a house that a friend is renting to take some pics, it is quite elevated and gives a fair perspective of the jungle around here, it was not a particularly sunny day so I did not use the telephoto lens.

First is a Google map of the area to give perspective between mountain and sea, actual location is not marked but closer to the mountains than the sea. All pics are from that house.



Looking towards my closest beach, Cow Bay, looking east



looking west from the house mostly jungle



The mountain range you see on pic one is a dormant volcano, Thornton Peak, most of what you see in these is Little Thornton, ie the lower slops,



Just looking across the jungle to the coast



Palm trees feature quit a lot here although I suspect not native to the area



While we were there about the second stubbie a thunder storm came up, quite normal for this time of year, the frogs become very vocal just before it rains and go quite when it stops.



This house has 750 Watts of solar, this is quite normal here and quite useless, but when government subsidies were 50% some retailer installed many of this size system, grossly inadequate.



Another view across to the coral sea





This is looking towards the east neighbor from this house , showing main house and two rental cottages



A front view of this house



A pic inside looking out



Under the house, these home are called pole homes, built on huge poles



A tree fern keeping pace with the veranda, there are several types of tree ferns here



A different aspect as the late afternoon sun came in, oh and down to cask wine, all stubbies consumed,



Ok that is enough for now

Hi Allan,

It was one of those 6 packs that led to my post.  :P

My current life's situation has me holding a job as a equipment maintenance technician that pays quite well, but consumes almost all of my time. I've always had dreams and ideas for inventions and adventures, and find that I now have the funds, but no longer have the time. (...some kind of cruel joke I think...  :( )

It's posts like yours that allow persons like myself to vicariously experience paradise while preparing for a NE Ohio Winter. (Somewhere in the American Rockies or northern plains someone is probably reading this and snickering. "NE Ohio Winter... Yah, right!")

I'm sure there are several grave hardships in your paradise that you must constantly fend off to survive. (Predatory attack birds wandering the jungle, possibly carnivorous vines hanging from the trees waiting to snatch you from the ground, etc.  ::) )

I hope you'll continue to post images and text (projects and environment) through your Spring, Summer and Fall.

Maybe someday I'll hop a plane (or several planes) and see about having that beer with you.

In the mean time... watch out for the birds and maybe the vines.

Can you please let the forum know what time and date the party starts.

I can bring along plenty of six packs of beer and if you would like a dozen or so of 20 year old Chinese dancing girls I should be able to find room in my luggage.

The place underneath your home seems suitable for a party BBQ disco etc and the girls are very obedient waitresses. I personally prefer all day and night party's that last for a couple of days minimum.

As for music, my preference is Creedence Clearwater Revival era stuff.

Glad I don't live in Ohio!

34F here right now, but if you think I'm boxing any of it up to send your way, you got another thing coming!  ;D

All it would do is make that much more "warm" air (as you put it) come down here and compound my problem, see... hahaha  ::)

David in HK that house is a friends place, mine is more in the jungle, as to party dates, here it is always party time, he was supposed to be evicted on the 9th but unlikely up here as a vacant house is a target, so we could have a party there.

12AX7 no snow here just need to get rid of the mold occasionally, a product called sanichlor which is basically chlorine works wonders.



Just exited the creek, having reclined for a good two stubies on my banana lounge, 26ºC in the water, rumblings in the distance but alas no rain yet today, 3mm last night though.

Some facts on my system which has been installed for 5½ months now, just recapping I live in Far North Queensland Australia, north of the Daintree River in the oldest rainforest in the world, said to be 130 million years old.

This area has no mains power and by current government laws can never have any, I won't go into that, I chose to retire here, it appeals to me, I was no novice to living off renewable energy so it was not scary to me. Anybody wanting a little background on power in this area can look http://www.daintree-holidays.com.au/daintree-pollution.htm, it is a little biased, and a government study can be found http://www.cairns.qld.gov.au/about-council/community-engagement/completed/completed-projects/power-study-options-daintree click on the imbedded  link on that site, it is a  PDF document but 5 MB in size.

Effective 1st June 2011 I had 10 Kw of  CNPV solar panels connect in groups at a nominal 110V DC to three Zantrax MPPT's. Batteries are Exide 1600 A/h @ 100 hour rate 48V bank,  or 930 A/h as used by myself (and most off grid homes) ie discharged overnight and charged during the day which means one has available the 10 hour rate.

In board terms that means a kWh rate of 46 for the bank and at a reasonable depth of discharge (DOD) to say 30% = around 14 kWh overnight.
We run two split system refrigerated air conditioners 24/7 that are about 750 watts each, this provides a good night's sleep and keeps humidity out of the house. This time of year is our summer and wet season most of the time it is 99% humidity and up to 32°C outside so mold is happy to grow anywhere and everywhere.

This time of year input to batteries is equal to load by around 0630 hours in the morning, most mornings are overcast but with these panels they make power.

DC input to the batteries;
 
7 day average is 16.29kWh/d
30 day average is 14.25 kWh/d
Year To Date (YTD) 2041 kWh
Here I must state that any input from the Little Lister is totaled in to these figures but total amount is fairly inconsequential.

DC out of batteries;

7 day average 13.64 kWh/d
30 day 11.59kWh/d
YTD 1599 kWh

AC load;

7day average 40.62 kWh/d
30 day 32.92 kWh/d
YTD 3459 kWh

Ac input;

7 day average 8.26 kWh
30 day 6.23 kWh
YTD 250 kWh

So battery efficiency based on YTD figures is 78%.

I run the diesel generator for about 2 hours in the evening to keep the DOD to my comfortable 30%, if I lived alone there would be no need to run it at all, the least said about that the better. Now my tests on the fuel efficiency of the LS series Lister which I run at 3kW load, is 0.39 liters/kWh, and at our price for diesel $1.65/L and after the government tax of 38 cents/L (I can claim that back) it costs 38 cents/kWh. I do not factor in any other running costs as that engine was overhauled around 9 years ago and by my reckoning it will outlast me.

It could be argued and in fact my figures support the argument that it would be more cost effective to run the batteries down further over night and replace them sooner rather than run a generator.

Yesterday, despite being a good power day I struggled for 100% charge due to some clown on an all night bender running the batteries down to 40% DOD, it does not go any lower because I set the inverter to trip at that point, probably explains someone knocking on by bedroom door in the wee small hours complaining of no lights. I can adjust that and re-start the inverter from the office but she does not know that and I ain't telling.

So that's the fact mam, just the facts

Wow man, looks like it really is paradise... ;)

Miles from distraction, juice coming from the aether, and a view from any of 360 different angles that is to die for.

What else could a guy ask for... Hmmm, yeah, ditch the neighbors noisy genny, and get some of them "waitresses" down there, and I believe you'll be at 110% of capacity in terms of "what to do with yourself"!

Color me green with envy, LOL, if I ever get my gravity assertion mechanism (pronounced "butt") to malfunction for any significant length of time, I too would be more than willing to transport it half way around the rock just to put it in "permanent vacation" mode somewhere in your vicinity. ;D

Very nice, indeed!

The size of the project matters not.
How much magic smoke it contains does !

Understood! Wish the little lady "Hello" from all of us.  ;D

What?!! Did David HK start his party already? I'm always the last to know.  :(

PS - You're definitely no newcomer to this RE thing. Very impressive!
