F150 not charging T@B trailer battery
November 6, 2018
I brought in my 2015 F150 since it wasn't charging the battery in my T@B trailer, this caused me to lose all the food I had in my 12vdc refrigerator a 3 week trip. Dave spent a considerable amount of time looking for an answer, even bringing in Jeff to verify what he'd found. After conferring with Fred, the service manager, it was determined that even though voltage was present to charge the battery it was of insufficient voltage and or current to charge the remote battery. There was 14.3vdc(charging voltage)on startup but it soon disappeared when the computer decided the truck battery was charged while disregarding the trailer battery that it showed was attached. While on my trip I'd met up with 3 other people with F150s and T@B trailers all of whom were experiencing the same issue of their trailer battery not being charge while travelling.
I have had excellent service from this dealership from Joe (Salesman), Lou ( Manager), The Service Department (Fred & Dave) and the Quick Lube
