How does Towed Battery Charger + work?

A. The Towed Battery Charger is specifically designed to work a 6-pin connector on the towed. A 6-pin umbilical has the 4 pins you need for the light system, as well as a pin for electric brakes and a 12V hot pin. When the Towed Battery Charger is installed, the motorhome is running, and the umbilical is plugged in, the towed battery stays topped off. 

Note: The TBC+ will only work if the pin it is attached to is correctly wired to the motorhome's alternator. If your hot pin is wired to a generator or house battery, your charger will not work properly.

A. No. The Towed Battery Charger is a one time install that takes about 15-20 minutes to install.

A. Yes and no. The Towed Battery Charger cannot get a hot 12V from the motorhome through a 4-pin umbilical. In order to bring the correct 12V to the bumper of the towed for the Towed Battery Charger to tie into, you'll need to either:

A) get a wire and splice into the wires behind the 7-pin connecter on the bumper of your motorhome 

B) if you have a diesel pusher you can tie into the engine battery.

(NOTE: We recommend etrailer.com or hitchsource.com for help creating a second umbilical.)

A. Yes. You'll need to create an umbilical that brings 12V and a ground from the motorhome to the towed vehicle's bumper in this scenario. In order to bring the correct 12V to the bumper of the towed for the Towed Battery Charger to tie into, you'll need to either:

A) get a wire and splice into the wires behind the 7-pin connecter on the bumper of your motorhome 

B) if you have a diesel pusher you can tie into the engine battery.

A. We always recommend that you follow what the owner's manual says to do for towing. In many cases the Towed Battery Charger will provide enough charge to overcome not pulling certain fuses.

A. If you have to disconnect the towed vehicles battery for towing, then it is recommended to disconnect the negative and positive terminal. Failure to do so could cause damage on the towed vehicle. The easiest way to do this is with 2 of our Towed Battery Disconnects.
