Hi,
First I want to say I trouble shot this and found the problem. It was a realobvious problem that I did not see for hours. I am only posting here so otherscan learn from my hard head.
The symptoms. When the unit would start it would come up fine, but the voltagein the auxiliary power outlet would go to about 146 volts and actually drift to145 to 147. (this could be my old meterand my older eyes.) The voltage adjust knobhad no effect. I plugged in a heater (1500 watts) and no change. So I put mymeter on the field wires and monitored the DC there and when I would load itthe voltage increased, as it should. When I would turn the voltage adjustmentknob on the front panel it made no difference. The fact that the field wirevoltage changed higher with load made me suspect that the transistors on theregulator board were good. Because it was regulating it was just regulating ata wrong higher voltage.
While tracing wires I spotted the problem. Should have looked at this first. Abroken wire on T1. (See photo attached) The wire was broken right at the eyeletcrimp so I did not see it till I gently pushed on it. With it pushed up theresometimes this wire made a connection and generator worked correctly sometimesit did not and I would get an overvoltage. (see photo)
Perhaps this will help someone else.
Look for broken or loose wires!!!
