Question:

I blew the Trailer Battery Feed on my 2016 F53 chassis. It is circuit CAT14 pin 4 on the 7 pin trailer connector. I can not find a blown fuse, Can you help me identify the Fuse number and location. Owners manual states this pin only has power when engine is running but doesnt list it on the passenger compartment or the engine compartment fuse listings. Thank You

I looked through the owner's manual as well as some wiring schematic for your 2016 Ford F-53 chassis and there is no mention of a 12 volt trailer tow battery feed. After some additional research online it seems as if this circuit was excluded from the F-53 chassis but I am sure the dealer would be able to give you a definitive answer. With that being said, it may be best for you to just run your own charge line from the coach battery to your 7-way. This can be done with the Roadmaster Battery Charge Line Kit for Motorhomes part # RM-156-75.
