No coach power. All chassis power items working.

Would that be a problem with the inverter, transfer switch, or something else? Generator won't start.

It would help to know what type of RV you have. Do your house electric items work when on shore power? If you can even plug it in to a 15 amp wall outlet it should give limited power through your converter/charger or inverter/charger.

Your transfer switch only works to switch between 120 v sources, shore power or generator. An inverter changes 12v battery power to 120 v AC unless it is an inverter/charger. That would convert 120 v shore power or generator power to 12 v power, then when not plugged in it provides limited 120 v AC power from the batteries.

Have you taken a voltage reading at your house batteries? You have power on the chassis items, so the chassis batteries seem O.K. When testing the house batteries, it's a good idea to unbolt the cable clamps and clean the connections, they could be the problem. Next, the house batteries might be turned off at the battery isolation switch, usually near the entrance. If you have voltage at the batteries, then the next thing to check would be the battery isolation solenoid. Also near that solenoid should be a large (80 amp?) fuse or circuit breaker to protect your wiring. If that is blown, no power past that point.

The starting point is your house batteries. If you own a multimeter, start by checking the battery voltages. They should be at least 6+/- v per battery. Check the area around your batteries. There should be one or two high amperage fuses (300 amps), check if those are OK. Next, check your battery shut off switch (if you have one) to make sure it is on.

Most coaches have a 12v "salesman" switch located in the switch panel when you first enter the coach. Check to make sure that 12 v is turned on (turning this off is the #1 problem that we usually see here when people tell us that 12v is dead). Check to make sure your charger is set to on.

These are generic troubleshooting steps. When you get done doing all this, please repost and tell us what you found - and you make, model, and year. Someone with model specific info can give you better help.

"Coach power" covers a lot of territory. Are we talking 12v (lights and such) or wall outlets and a/c units? The transfer switch changes the source of 120v power from shore cord to genset, so probably not involved (yet). More likely you have the house battery bank switched off, or they are dead. Many things won't work if there is no house 12v active, e.g. the thermostat doesn't work so no a/c or furnace either, and the fridge doesn't work because its circuit board needs 12v too.

The generator starts from 12v battery power too. If it won't crank, it isn't getting battery power. Does the coach itself start up? If so, start it and then try to start the genset. The engine alternator will supply 12v for genset starting in most Rvs.

It was battery disconnect switch, someone had accidentally hit the switch. Kind of scary when everything quits working at 70 mph. Thanks for the reply.
