Hi- I have a multi-plus 5000 and was playing with the (shorepower) input amps raising it from 12 amps as set to 15 amps. Didn't think it was a big deal - but now the inverter has totally stopped working. I can get AC power through the battery charger pass through, but if I unplug from shore power I get no power on the boat.(no inverting) - course batteries are fully charged. When I turn it off and on again, the green light on the inverter comes on for just a second then it immediatley trips back off and no lights are showing after that. Help please?
