Hello,
I have a Generac RV Q55-G and it lost AC Output. (was working in the days leading up) I was following this post repairalmostanything.com/thread/11/generac-55g-putting-out-power . I was hoping you could assist me...my problem is very similar . I followed the trouble shooting in the above post as follows...but then it stoped
I have a 30 AMP Plug...
Voltage Regulator LED Not Light Voltage at 30AMP plug is ~ 2.6 V AC Circuit Breaker has continuity Fixed Excitation Test ~ 40 V AC Third Wire From Top During Cranking ~ 4 V DC Then ~ 1 V DC Third Wire From Top Disconnected... One wire reads ~0-1 OHM and the Other ~42 OHM Third Wire From Top that read ~ 0-1 OHM Reads ~ 12.9 During Cranking
Thank you for your consideration.
Aaron

2 of your numbers look like they could be off just enough for it not to output power. Your fixed excitation voltage is low and your 42 ohm is high. These are actually inter related. A higher ohm rating will give a lower excitation voltage.
Try doing the 42 ohm line test again but put your negative meter probe right on the generator case (not motor case) if you can find a nice clean spot.
