Part 1#

Dose amy know about SOLARGIZER  Desulfator

It as given  to me  every expesive ,

I see      

this one is ( IS-24- L )  24 volt

industrial solargizer.

Question:

can this be used on 12 volt batterys.

will it work ? will it hurt the batterys ?                                                                                              

Part 2#

Can someone tell me the characteristic

of cogging , what to look for with the

wind mill 65 ft in the air .

Dastardly;

Dose amy know about SOLARGIZER  Desulfator

Amy who?

Can't help with the desulphator, it won't hurt the battery but it may not work at 12v.

The indication of cogging on a machine 60 ft in the air will be the fact that it isn't going round. I thought you built an air gap alternator using HD magnets. If so it can't cog.

Your right it's HD magnets . At

a low speed maybe about 4 mph the tail

shakes right to left maybe 1 inch,

not up and down.

this gose away as rpm increse

The blades are balance, number one blade

will stop any where on the clock , with no back roll.

[dastardlydan]

thats becauses they are side by side

[dastardlydan]

I call the company they were on help

said 24 volt 1.3 mil amp.

and that was all they could tell me.

Question

if you have 4 batterys in parallel

how would you hook up the desulphator.

Thank for the right spelling.

The wig-wag has nothing to do with cogging.  It, combined with the "stop anywhere", indicates your blades are in static balance but have a dynamic imbalance.  They're probably not exactly at right angles to the axis, or one or more of them are slightly bent.

Since it's a gentle yaw and stabilizes as speed picks up I wouldn't worry about it.  (The bades probably have enough flex that they bend into a more balanced cofiguration as the mill picks up speed.  Trying to fix it might just make it worse.)  It's a little more motion on your yaw bearing and flexing of your drop wire but it doesn't look like a significant problem for material fatigue beyond that.

I've just posted a long article on cogging in response to Willie's question a couple articles later than this one in the homebrew section.  See if that answers your questions.

Hurrah for your successes with your mill!

I take it that you have 4 12v batteries in parallel.

If so you will probably not be able to use the desulphator if designed for 24v, it all depends on the internal circuit.

Most of these things produce a string of fast high voltage pulses and it may well still work at 12v but you can't be sure that it will pulse at the lower voltage.

The solar panel is probably to supply the loss caused by the pulser and will still put a few mA into a 12v battery.

Alternatitively it may be a scam and is only a trickle charger, in which case it may work as well at 12v.

Don't think I was correcting your spelling, I am in UK and we spell a lot of things differently, doesn't mean that you were wrong.
