Good to hear. I take it the pump was not damaged -- at least not that you can see at the moment. I have no idea how well those things are protected from accidental reverse polarity. It could have been well protected and there was no damage but the fact it was pulling down the coil voltage means some current was getting thru. If it is your only source of fuel supply I would be careful and keep a watchful eye or be prepared for sudden failure. Most solid state devices are unforgiving and once the deed is done can fail without warning.

I am curious about the ammeter. Some have had to reverse the wiring to theirs when the polarity was changed. Did you have to do anything to yours and have you confirmed the ammeter is reading correctly and generator is charging properly.
