Grubby alternator
« on: February 06, 2006, 01:44:43 PM »
Hi

The alternator on my 1990/1 JLX died a few days ago (at night, of course  :P).

I picked up a used one via a friend.. unpacked it tonight-- its incredibly filthy. Thick clumps of black grease and dried mud caked onto it (I've been assured its in good working order...).

I've got 90% of the crud off the outside, but my question is this- pls excuse me for being a bit of a noob - am I ok to use a bit of engine cleaner/ degreaser and a jet of water to clean the little bugger? If not, what's the best way to do it...?  ???

Cheers

If your going to use a degreaser make sure you let it air out or blow compressed air on it to dry it good.. Don't wanna see it go up in flames...In  the altenator rebuilder shop i worked at a few years ago we used to run all the parts" rotors, stators, brush holders, and internal regulators" not to mention the 2 halfs of the cases too thru a hot water steamer.. As long as it's dry when your ready to reinstall it you shouldn't have any problems.Even though your friend says it's good you may want to get it tested after you get it cleaned up . ;D

hey,  you might be a guy to talk to, every time I submerge my tracker with the new alternator, it dies.    Older factory alternators used to last me months, the new aftermarket od rebuilt ones die the first time theyre submerged... whats the deal?  I thought it's the volage regulator getting caked with mud and overheating, but the last time it came out clean and it still died....

The secret is the caked on dirt keeps the regulator from getting wet.  ;D

electrical contact cleaner -----  from pyrol blast it in until it runs clear --- and the watter thing I am a comp guy and i ahve seen strange things but usualy if you get an electronic device wet,  as long as you let it THROUGHLY dry your all good.
