microlite 2.8KV

[rldavis]

Onan Microlite KV - model 2.8KVFA26100K - spec K

Generator was starting and running 120 no load 115 load for 20 minutes and would die. Gradually reduced running time to under 2 minutes.
Now will start and run only with the start button down. Initially would do this and produce voltage - now produces no voltage.

I have cleaned the slip rings and replaced the brushes. I cleaned the brush block (brushes were not stuck) the block is not cracked or damaged so reused it.
I had the rotor and stator megged at a service shop and both tested good.
I tested the VR and according to book it is good (But can still be bad.
Ran 12 volts through pin 9 and grounded pin 10 of the generator side of the VR connection - no volts.
This is supposed to bypass the VR - what have I Missed???????????
Thanks,
Robert Davis

When was the oil changed? I bought a WW once and the 2800 would die when I loaded it. Changed the oil and wala. The oil I drained out was as thin as water. It never gave me a problem after that. The PO just neglected it. Shame it was neglected that way.
