So I have an Onan that runs great but doesn't make AC. Pulled it and found the field coil was bad. Located a good field coil, installed it, checked the rectifier, the breaker, etc, hooked it up the coach and fired it up, no AC! What could I be missing?

The only thing that isn't hooked up is the pigtail that goes to the coach controls, but that shouldn't have any effect on AC output. Also, where do you measure AC output at the Onan? I've measured from both sides of the breaker to ground (the Onan case) and it only reads about 2.5 volts AC.
