Question: I have a 2002 31ft Fleetwood and switched from 2x12 volt batteries in parallel to 2x6volt in series but they don"t seem to charge. I have the power coming in from the chassis going to the negative terminal of the first battery and then the line that goes to the coach I have it connected to the positive of the second battery. I also have a small gauge wire that goes to a breaker next to the battery which I have connected to the negative of the first battery. I think I'm doing something wrong


Robbie: Look at this picture I made for you (above) and be sure your connections are the same. From what you wrote it appears you've hooked the batteries up backwards. Good Luck and let me know if this does it for you.

I've been a technician in the RV industry for 30 years, operating out of San Diego, California. And let me tell you, I love my job.

But I also love empowering RVers with the knowledge they need to make the right decision on repairs, or to make the fix themselves--and that, my friend, is the reason for this website. I hope you enjoy.
