Last week I had a lengthy thread going for advice on my Onan that was not producing AC. Having read that again I have decided to start a new topic as most of the previous topic was around getting the Bridge Rectifier (BR) tested and replaced. Many thanks to all who helped.

At this point I am fairly certain that I have a good BR that is properly installed. I have measured the field coal resistance across the F-1 and F-2 BR wires and have the proper 38 ohms, and I am getting 2.9 volts of AC measured inside the coach at the electric panel. I understand that this low voltage is typical and is due to residual magnetism.

What to do next?

From reading Jim Miller's posts I understand that possible next steps might be to test the Reactor (although these seldom fail), or to possibly "excite" the coils with a battery?

I also read through my old threads and looked at dates. One fact I may have had wrong is that I don't think I actually used the electricity since last fall. I had run the engine several times over the winter but I did't actually check or use the electricity. I don't know if that changes any view on possibly needing to "excite" the coils.

Advice on next steps would be appreciated. Saturday is my opportunity to spend a little time with the GMC.
