Problem with House Batteries

SR71 wrote:
I recently changed my four 6v house batteries in my '99 Fleetwood 37V, but now have no interior lighting at all. I marked the cables and drew a diagram of the wiring prior to removing the old batteries so I'm pretty sure I rewired all four batteries correctly. After the new batteries were installed I measured 12.8vdc leaving the series/parallel house battery wiring to the Inverter - but it seems 12vdc is not reaching my interior lighting. I've checked every fuse and circuit breaker i can find, but cannot find one that is identified as "interior lighting or "house wiring." Anyone with a similar year Fleetwood know where the interior light fuse is located?

did the system work prior to replacing the batteries. If so you have a miss wire . Can you post a picture of the top of the batteries with the wiring. The below pictures are fro 12v and 6v. They also are connected to give you a balance power, meaning they should last longer and charge the same to each battery. post back. we can not help you if you do not reach out more than once.

Here is a picture from the web. wiring
