I guess the problem I am having is I am not sure the wiring is correct to the inverter. the inverter has a in put and output. Before we unhooked the heartinerface model I marked how they where hooked up to it, then connected them to the 458 in the same way. but no 110 volt power out of the inverter.
The battery are 12.7- 13 volts. They are about 7 months old and when hooked to shore power they show 13.3. Anyone out there made the change from the heartinerface to a 458 freedom single input single output inverter? thanks
