I am still working on this generator from hell. I thought and still think that I still have all of the wiring corrected. Now I am fighting a blown 5 amp fuse after starting. It does it almost every time. I finally installed a temporary circuit breaker to keep from going through fuses. I think I have traced it down to the fuel pump. A Fluke amp probe show a stead 3.1 amps going to the board with an occasional very brief jump to slightly over 5 amps. I will try a replacement aviation Facet or Bendix fuel pump tomorrow. If it were voltage spikes I could see it on an oscilloscope but I do not have am amp probe for it.

The second bug is still the up to speed circuit. I had it working for a while and not it start and stops again. I finally checked the output of the alternator and it is a steady 24 VAC. It should be 28 to 30 or 31. Tomorrow I'll probably remove the flywheel and inspect the coils and inside flywheel for dirt and rust. I can see no way to bring up the voltage other than that. It reads 24 VAC (NOT 28) when plugged into the board or disconnected from the board.

My final shot might be to jumper out the resistor in series wit K2. I do not remember the value of that item on a dinosaur board but I though George Z's resistor read something like 22 or 44 ohms. On the genuine Onan board that resistor is 200 ohms.
