Fuse issue

[heck198]

I have a 2015 F150, 2018 Vengeance 28v ... I have used this trailer plus my Wildwood and never had this issue until recently ... I have popped the fuse for my trailer circuit on the truck twice now .. I have never had this issue until recently. I lose the power from the truck to the trailers auxiliary, such as fridge and electric jack , clearance lights and all other exterior lighting works .. I've checked to make sure everything is off while hooked to truck , I've never had issue of running fridge while hooked to the truck prior ... anyone experience this before or have any suggestions ?

Ensure that your trailer batteries are up on charge to prevent it from drawing to many amps on plug in.

Thank you sir, after some some searching I discovered the ground was loose on the batteries ... explained why it happened while transporting ... thank you for the reply sir !

Are you blowing the 30A fuse for the charge circuit in the battery junction box or the 10A fuse in the central junction box for the relay that the charge circuit is fed through




NEVER MIND... I see you posed your fix as I was gathering information.
Thanks for reporting back and good job finding it!
