12 Volt System On Our Motorhome Not Working Unless We Are Plugged In

by anonymous

We have 2 Deep Cycle 12 volt batteries which are both good. Lights don't work on 12 volts. Monitor does not work on 12 volt, which includes water pump and water heater. Generator will start from monitor. Refrigerator will light with 12 volt.

Everything works on Electricity and everything works with the Generator running. Does anyone have any ideas on what could be causing this problem?

ANSWER OK, for the first time ever, I am going to stay out of answering this question. I have a sneaky suspicion on what is going on here, but I am going to open up this question to our visitors.

Do you have an idea of what is causing the electrical problem with this motorhome? Please click on the post comment link near the bottom of this page to give your answer.


Just a hint, look around our site at some of the previous questions that have been asked and you might just find the answer in one of those questions.

Happy RVing

Push the little black buttons on all of the relays hooked to wires in the battery compartment. If this does not correct, disconnect the inverter. If everything in rv goes off, your inverter is malfunctioning.
