Dougiefrsh1 Posted June 7, 2018 Share Posted June 7, 2018 When I am plugged into shore power everything works. How do I unplug from shore power and use coach power. Once I unplug from shore power nothing in the coach works? There are brand new batteries hooked up. I am a new Toyota rv owner Quote Link to comment Share on other sites More sharing options...
linda s Posted June 7, 2018 Share Posted June 7, 2018 Check your fuse box in your power converter. I guess it's possible they could all be bad. Only 12 volt things will work on coach power. Your 110 outlets won't. Linda S Quote Link to comment Share on other sites More sharing options...
Maineah Posted June 7, 2018 Share Posted June 7, 2018 There is another possibility, inside of your converter there is a relay here is what happens. When you are plugged in the relay closes and disconnects the battery from the coach the converter then charges the battery and supplies 12 volts to the coach it is possible the relay sticking in the on position when you unplug this is not an uncommon problem so even with a fully charged battery it has no way back into the coach electrical system. You might try giving the converter a good wack with your hand this sometimes frees the relay. Inside the converter there is a fuse panel there should two large lugs between the two with the camper unplugged there should be 12 volts if not there is a poor or disconnected lead to the battery if that's not the case then the relay is stuck on. Be advised when playing with this system the relay is energized with deadly voltages from the power cord so caution is of the utmost.
