    Hi There > can anyone tell me what fuse charges an auxillary battery in a trailer?

    my brand new battery is not charging and it looks like Tundra is not charging it as i have a meter reading in horse trailer

    i’ve checked the fuses that say they go to trailer and they look good. However my truck does not have fuse 38 in it. Im wondering if that is the issue.

    i dont think this truck has ever charged a battery but i always blamed it on battery.....

    but it seems to have never charged when pulling a bumper pull or this gooseneck.

    i called the dealership and they said trucks cannot “recharge” an auxillary battery which i disagree with.

    this is a 2012
