Does the ETBC7 Kit for a 2012 Toyota FJ Cruiser Have a 12 Volt Circuit to Charge a Trailer Battery
Question:
Does the ETBC 7 Kit allow for charging of the trailer battery? Which pin would run a trickle charge to the RV battery?

Helpful Expert Reply:
When installed according to the FAQ and video I have linked for the # ETBC7, there will be a 12 volt power circuit on the 7-Way. If you are looking at the pins of the 7-Way the 12 volt circuit will be in the 1:00 position. This circuit will provide a maintenance charge to a trailer mounted battery, but it will not charge it up.
The wiring to the 7-Way and the vehicle alternator are not large enough to push back the amperage needed to charge up the battery. It will however keep the battery at the level it is at. A battery charger like # CTEK56353 is recommended to charge a battery when you have access to shore power.
The CTEK battery charger will not overcharge a battery like old trickle chargers. It will also help to recondition a battery. I have linked an FAQ article on battery chargers for you.
