Onan 7000 Generator problems

[Rich Biebel]

I have bought items from ASAP and that replacement is a very recent item. Cummins price is now well over $500 for one. Yes they say Made in China right on them just like so many other "name brand" parts we buy.

I have not used one of the ASAP replacements yet but definitely planned to in the future to offer a better price for one.

If the brushes were still contacting the slip rings and the rings themselves were not in real bad shape, that is probably not your problem.

They will wear down so far the wire shows thru the carbon and the slip ring gets pretty burned from arcing....

I check them routinely on any machine that comes in with at least 500 hours. I have seen them worn to failure at somewhere around 1000hrs.

One brush is always worn more then the other. The lower one. The wire ends have locks on them....you need to use a small screwdriver or something to release the lock......1 at a time so you don't mix them up. It is DC voltage there and will work either way but is shown in the manual a certain way. I have found them wrong a few times....I forget right at the moment which is positive...
