2018 Ventana 40'TAG
Had a power failure at the campground this weekend. When the power came back on, the Inverter control panel is showing a failure 3.4V and blinking. Voltage tested at the battery bank is 13.6V. The readout shows Dead Charger Battery and there is no 120V to operate the appliances or internal receptacles. Incoming power to the coach monitored by a surge/voltage protector is good, 120v on each leg showing on the control panel and the A/Cs work. What else should I check before condemning the Inverter.
