I have a Multiplus Compact 12v/2000/80 in an RV. It has worked fine for nearly a year. I recently removed the cover to connect the trickle charger to my engine battery. That works fine. However, the Multiplus will no longer pass through AC. I hear the relay click (backfeed relay I presume) but it immediately releases. I'm hooked to shore power which is stable at 124VAC. (Btw, I disconnected the trickle charging wire to see if that could have somehow messing things up. It didn't help.)
Any ideas?
