tt battery charge

Does the Excursion help charge the battery on my travel trailer while driving? I never boondock but have a new electric tongue jack and wonder about that. I know it charges with a shore line I just assumed it did while driving too.

Thanks

Yes, one of the pins in the 7 pin is a +12V switched. It will charge your trailer battery if your trailer is wired to do so.

Yes I am, Thanks I just put a new battery in the tt, the old one was prolly 7 years old and didn't work to well haha. We are going to the beach this weekend And it just occurred that it might not charge while driving.

I would check and make sure you don't have a blown fuse or something for that 12V.

I guess I could test at the plug itself, It's marked fairly well on the plug.

Thanks!

I had 2 12V group 24 on my TT; I just changed to 2 6V Golf Cart Batteries. Getting ready to take it to the beach Sunday for a week....hoping the new batteries do better than the previous....

You can verify by grabbing a multimeter:

No need to check at the plug. Just put your meter on the trailer battery while hitched to your Ex with the engine running. You should see more than 13 volts on your meter. That way you know what your battery is actually receiving while underway.
