It is wired that way to prevent the discharge of the TV battery...

The gen set will keep the battery charged thru the converter which has a multi stage charger built in....

On the picture from F6bits, your TV will not charge the battery or your battery will not operate any 12 volt inside lights, ref, or furnace if this braker is open. You can get a replacement braker for under $10.00 at any RV store.

If you read your manual, as useless as it is, it will tell you not to operate your slides without a fully charged battery. It is also recommended to have TV connected with engine running or shore power to avoid damage to slide motors from low voltage. Electronics that require "clean" 12v dc power also need the battery to filter the converters dc output. After you arrive at your campsite with your TV connected and running push the battery button on your control panel ... If it reads full everything is working the way it should be, no test equipment required.

Since you have a generator, Take the trip with battery connected (and disconnect on) and see how the system works like Keystone designed it. I think you will find that your battery will charge while towing and you will enjoy your new trailer. ..... Travel safely, Hank

Javi, I know that the truck is wired so the 12V is only active when the truck is running. *That* way is how it stops the trailer from draining my truck battery.

camper_2010, yep, that's the problem I'm facing. I'm working my way up the learning curve in finding out why I wasn't getting power in all the right places. I've been adding/replacing parts as I work my way through the circuit. Looks like a new breaker would be next, but I need to pull the old one to find out what its amperage rating is.

hankpage, yeah, I know the truck should be running when running slides. I've been a good boy and left the truck running as I set up, but only now discovered that it was for naught since the trailer isn't getting its proper 12V from the Tow Vehicle. Once I get a new circuit breaker installed, I'll know for sure what's really going on.

Just got back. No, the batteries didn't charge a whit during my 3 hour drive. On Wednesday, I'll remove the breaker and get a new one.

Victory! The circuit breaker was bad. Replaced it and the truck is powering the trailer as it should.

Thanks, all, for the tips and guidance.

f6bits,

I'm glad you found the problem... Now, go back and read post #10..... <wink> The answer was there after a short discussion after the other things that could be wrong were eliminated.....

Now that it's working properly, park it somewhere and enjoy Thanksgiving

Happy Turkey Day to you and yours !!!!!!!!!!!!!

John

Yep. I remember that post. That was a key piece of information I didn't have before. When I installed my cutoff switch, I utilized that breaker for connecting a cable, but didn't realize it was a breaker and didn't know what all was connected to those posts. After tracing circuits, it all made sense. Thankfully, my local RV parts/repair shop had a replacement.

And, in case you haven't been keeping up with the older topics, there are no wiring diagrams for any Keystone products, so you're pretty much left to your own devices in trying to figure out what goes where.....
Hello... I think I may have the same problem... Posted this thread:

http://www.keystonerv.org/forums/sho...7586#post57586

and someone told me to look here...

I have a 2008 Sprinter 311 BHS. I looked for what you described but could not find it. Is this something that I'll have to remove the bottom of the RV to find?

I looked near the battery - no dice. All I see is a junction box and when I opened it up I just see the wires connected - no capacitor.

Is this located perhaps by the circuit breaker panel? I opened that up and didn't see anything like you described.

Would appreciate any help... If you click on the link I provided, I described my issue... May possibly be the same thing?

Thanks,
Herk

(Edit - nevermind... mystery solved. Battery was dead - and when I looked at the connectors, noticed there was some electrical tap (???) blocking the wingnut. Removed electrical tape - plugged in trickle charger... presto! Everything works...)
