I currently have two Multiplus 3000 12v, one on each leg supplying power to my RV. We have been running for slightly over one year with no issues while running both generator and shore power.
Now AC-1 IN is working on shore/generator power no issues. This Multiplus is the charger.
AC-2 IN is showing voltage and HZ but will not pass through. This multiplus is only inverting.
Does the multiplus 3000 have any internal fuses or contacts which could be the problem?
