New Coach Batteries Not Powering Coach

[challengerros]

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. Help!!!

All you can do now is start at the batteries and trace the voltage to where the power is being lost. Calling the MFG for their suggestions and wiring diagram woud also be helpful. Since the entire coach has no 12V when on batteries, that narrows it to one of the components mentioned in your OP or a bad ground. Be thankful it is a hard failure, you will find it.

One last thought. If the battery ground is good, there could be an inline fuse between your batteries and where they connect to the coach.

I sense your frustration. By reading your post I can tell you know how to troubleshoot. You said that you replaced the battery disconnect relay. Take a look at this pdf document on Intellitec Relay because I think that is the one you have. The positive of the battery bank goes directly to the relay first. You should be able to find 12 volts on one side of the relay. If not, depending on where you put the ground lead of your meter, you have proven that the positive lead from the battery bank and/or the ground lead is not connected to the point that it should be. Also, there are fuses mounted on the relay and it will not connect the battery bank to the coach if one of them is blown. I hope this helps. Let us know how it turns out.

Welcome to IRV2, I see this is your second post. Hopefully Retired SKP is onto to something, I have also known relays that I replaced were bad, so you might want to verify that as well. Let us know so we can all make a mental note of it!

Did everything work before you changed to new batteries ? If so, double check all your connections..and the obvious like your battery disconnect switch on your dash (not your aux start switch)...

Check all fuses and cables with an ohm meter, not just a visual check. Sometimes bad fuses look good visually.

[challengerros]

Yes, everything worked perfectly before. I've checked all the connections. I checked my disconnect switch and it too is working.

RESET buttons in your Intellitic distribution box. they pop out , need to be push back in. If no power to coach lights it is the RESET button . Even if you have coach lights with shore power , it is the RESET button that pop out for the battery to use for the 12 volts outlets..

Welcome to iRv2.. Challengerros

Is it in the box? Do I need to remove the cover to get to them? It has to be something like that. But I do not see any buttons on the outside of the box. Thanks for your help!

Thank you!

yes it is in the box , take off the cover and look for the main battery cable coming into the box. and also there is a coach battery line going in. on the right side of the box on the inside edge. Look on the side of the bus mount plate and you will see a black button that is pop out , it needs to be push back in , do it on both for the chassis and coach battery if you have both. like mine does.. Some only have one.
or go to the intellitic site and look up product page and the click on Technical service then click on Service Manual then look for your system either gas or diesel then click on that , it will be in Adobie PDF format, there you will see
where the button is , you will need to enlarge it.
Or call the phone numbber listed on the home page and ask for VICTOR in tech dept . he will help you find it and where to look. Believe me it will surprise you because you would never think of looking there. it is in a strange location. Here is their phone number 1-630-268-0010 ask for tech dept. and get a hold of Victor.
