Coach Batteries Not Powering Damon Challenger Coach

challengerros · 02-11-2008, 02:42 AM

I have a 2005 Damon Challenger 353. I recently replaced my coach batteries and now nothing is working off my coach batteries. Here's all the facts: the replacement batteries are new (2 6V in series), they are showing 6.2 Volts individually and 12.4 Volts in series, they are hooked up correctly and there are no lose wires, I checked all known fuses and breakers, I replaced the BCC (battery disconnect relay) and the solenoid mounted right under it, the Aux. Battery / emergency start feature works fine, and everything works perfectly inside the coach on shore power and while the generator is running. There are 2 30 Amp fuses at my converter that both looked/checked out on my meter but I changed them anyway. Does anybody have any suggestions? I've been troubleshooting this for two weeks now. I'm getting a little frustrated.

Do you by any chance have an Intellitec battery control center box? Mine is located in the front compartment above the radiator. There are two manual reset circuit breakers with very small reset buttons located in the bottom of the box. They are easy to miss but will kill 12v to the coach if they are tripped. Just a thought.

Hey Jim, I keep thinking this is what the problem is. A few people have suggested there is a box in the front of the coach with a breaker but I swear I cannot find one...any idea what it may look like? I'm going to look again right now!

Thanks for the input!

Well it's a black box about 8x8x3 with Intellitec stamped on the front. It's similar to the box at this link.

Thank you. My box looks totally different and it does not have a breaker. My gut is telling me it's a fuse or a breaker but I have looked high and low and not found either. I'm sure it's something silly since everything else is working fine off shore power and the generator. Thanks for your help.
