Voltage regulator

I own a 2003 Fleetwood Providence and yesterday while traveling my battery light came on and off several times. Eventually the battery light came on and stayed on. My voltage gauge started dropping. I turned the generator on which allowed the voltage to rise again thru the rv batteries. Can anyone tell me what to do. I am stuck in Gettysburg on a Sunday and need to travel along. thanks

Your alternator is not working. You are fine running the generator in place of it until you can get it replaced.


You can change the setup at this site to match your vehicle system. It is possible to have a diode isolator go bad too. In some cases one would have to force the emergency start button to stay on to keep the voltage going to the engine battery.

Check the connector on your alternator [wiggle] and make sure it is in tight and clean. Mine lost connection in the past, firmly pushed in and it snapped and all was fine again.

Your alternator is bad on the engine, run your genny till you get it changed. Jim

It may be as simple a fix as plugging it all the way and zip tying it to stay in. Our voltage regulator had that problem, the plug had wiggled it's way almost out.
Ours are 2 separate pieces but most now come with the voltage regulator integrated with the alternator.
If it really is the alternator then you may want to run with the generator until you get home so that you can look for the best part and price at your leisure.
You may end up needing to just checking/cleaning/fixing all grounds for your engine/alternator as that may be your problem.
