Does Brake Controller Drain Battery

Does Brake Controller Drain Battery. You can install an ignition controlled relay which would isolate power to the unit when the vehicle is off, however this adds a switching device to the input which if failed the trailer will be without brakes. In this setting, the power draw falls to minimize drain on your vehicles battery.

The customer started having a battery drain issue and of course the dealer blamed it on everything i had put on. I have a traxide dual battery, tokensha p3 brake controller and the anti rust gear. I took the car to lr to see if that bulletin about getting the message was applicable.

It sounds like there is a short somewhere in the system that is drawing power and draining the battery. That indicator draws such a low amount that your battery would die from inactivity before it would drain it. Assuming that the battery is in good shape and the alternator is operating properly, the most likely cause is an internal short to ground in the brake controller, which would explain the spark seen when you unplugged.

I have an 06 2500 gmc 6.6l dmax 4x4 with a brake controller and a bully dog chip. As long as no trailer is hooked up to complete the circuit it should not drain. This power draw is so small that it would take several months for the power drain on the battery to be of any concern.
