RV Electricity – Just Ask Mike (J.A.M.): Generator starving for fuel?

Welcome to my J.A.M. (Just Ask Mike) Session, a weekly column where I answer your basic electrical questions. If you’re a newbie who’s never plugged in a shore power cord (or ask – what’s a shore power cord?), or wonder why your daughter’s hair dryer keeps tripping the circuit breaker, this column is for you. Send your questions to Mike Sokol at mike (at) noshockzone.org with the subject line – JAM.


RV Electricity – Just Ask Mike (J.A.M.): Generator starving for fuel?Dear Mike,

I’m fairly new to the RV world. Is the on-board generator designed to shut off when the gas tank in my motorhome gets to a certain level? My tank is down to ¼ full, and I can’t keep the generator running. Acts like it’s starving for fuel. —Sean

Dear Sean,

That doesn’t seem to make any sense, does it? Well, in this case your generator is actually starved for fuel, and it’s done on purpose for a very good reason. Because your generator is tapped into the same gas tank as your motorhome’s engine, the pipe for the generator fuel is typically located about 1/4 of the way from the bottom of the tank.

Inconvenient for sure, but you still have enough gas in the motorhome tank to start up your engine and get to a gas station. Pretty simple and practical fix, isn’t it? After all, you wouldn’t want your generator to use up all of your gas and you have to walk instead of ride, would you?

OK, everyone. Remember that electricity is a useful and powerful force, so we all need to pay attention to safety precautions while using it.

Let’s play safe out there….
