2007 Hurricane 12V Question

New here with an electrical question. We have a 2007 Hurricane. Recently, the 12 volt lights have been dimming and then going back to bright. I have noted that "the system" is switching from coach to chassis battery on its own. I have not volt checked the batteries but intend to when we get home this week. Any thoughts on where to start my troubleshooting?

Welcome to irv2.
It maybe time to check your battery terminals for corrosion and just plain dirty posts plus the battery cables connections on your chassis frame the negative cables which you have ground cables for Gen and your converter/inverter.
Treat all battery connections with the spray terminal protectorate and use star washers on all you chassis frame connections so they do not loosen up.

I had the same issue with our 07 Hurricane. It was a bad solder joint on the main board of the charger/converter. I fixed that then a few months later the charger/converter quit working and I replaced it.

I'm not Texnet, but the way I do it is to wiggle wires and components until something changes. First rule of trouble shooting - Smack it. If that doesn't work, reseat all connectors you can get to.

Mine did the same thing. Changed the converter, problem solved. Check your converter, when it goes bright, the converter fan will come on and go off when it goes dim.

But,

if yours is changing between coach and chassis batteries, that sounds more like a BCC problem under the hood.

If your BCC is a model 2050 from "RV Custom products" then here is the schematic and troubleshooting guide.

Well, it would appear that the coach battery was just about done and wouldn't take a charge. I replaced the batteries and so far so good. Monitoring the system right now and think we might just be ready for the road again! Thanks for the input, learned a lot about the rig from this.
