And much thanks TripleJim and all others!

Ok. I'm will hopefully get the other board tomorrow. It looks just a bit different. The rheostats are a different form factor (long and rectangle vs mine that are small and square). I can't help but wonder if I should be testing the transformer and anything else in the circuit. I don't see...

Cuad4u- I checked the voltage adjust rheostat and it was indeed 0-1k ohms

TripleJim for the win!!!! Disconnected wire 17 at the voltage regulator and I have 165 VAC! I'll swap it out and keep everyone posted. I should be able to repair the old one, but it may test my skills...

Voltage adjustment rheostat seems fine.

I was reading an old thread over on ,smokestack and it was saying the exciter field should be getting 12vdc when holding start switch to start with unit running. I'm only getting 5, but it is generating while it is flashing. I guess this is a clue. It is possible my voltage adjustment...

Thanks Triple Jim. I'll give it a shot. Luckily I have a couple parts gensets nearby where I bought mine. I just hope it isn't the actual generator head.

The regulator board looks ok. I see the bench test procedure in the manual, but it looks like quite a process. I think I have to pull it and two transformers and wire in two switches. I was hoping for an easier way to test it. I know overload can cause field collapse. Is there some...

I was talking about the diode bridge board, but I pulled it and checked all 6 diodes and the resistor. That was all fine.

I see that diode CR6 is a bit discolored/malformed. CR1, 2 and 3 seem to test ok, but CR 4, 5, and 6 all go to the same terminal on the board, and not sure what I should be reading if they are working properly without removing that board. It seems like the whole board is potted, so I can't...

Thanks for the reply. I did try that, but it wasn't tripped. There is also no voltage at the auxiliary outlet. I was just messing with it and found that if I hold the starter switch to start when the set is running, it outputs voltage to the outlet. I was doing this to reflash the magnetic...

My genset quit on me in the middle of a power outage a couple nights ago. The motor struggled for a second, it stopped generating, then the motor recovered to full RPM with no output voltage. It starts right up now, but only outputs 1 vac. Any help with how to troubleshoot would be very...
