Help identifying AC generator part.

I've put this in my Diary section as I don't think it fits anywhere else.

I bought this Honda clone 6.5kVA 240V 50Hz generator on eBay

for a bargain about 2 years ago. So far it has seen me through two

cyclones and several power outages. It is said that our neglected

grid power distribution system is third world by standard. Watching

the lines men screw broken power poles back together after the last

cyclone confirmed this theory.

Anyhow, our cyclone season is fast approaching again and I have

been preparing the generator for another season. I opened the rear

cover on the alternator to check everything and also find out what

method is used for excitation and regulation. As per the photos

below, it appears to be a 2 pole 3000rpm brushless capacitor

excite design. I removed the black odd shaped item that I suspect

is the capacitor. It measures 35uF on my Fluke DMM, but has

no markings at all to confirm this. I'd like to buy a spare in case

it fails.

Am I right in my theory here?

Buy a 35uF motor run capacitor of the highest voltage you can get and mount it externally if you have to use it in an emergency, That queer shape thing will probably cost a fortune if you can get it.

Thanks Flux.

I thought about the external mounting idea after

not finding any reference to that part in Google.

Might even get a few above and below 35uF

just in case it is already down on value.

The potting compound makes it look like it's got

several smaller caps inside it.

        just a short thought.

I noticed some cracks on the mounting holes and on the

main body. Maybe a spot of silicon would help it last.

  And maybe the local airport or courthouse wouldnt mind

scanning it for a better idea of of the inside arrangement

 without cracking it open. good luck.
