Ok so I was at my Dads today and noticed a pulsating tapping noise coming from the brakes. It turns out that our 2012 and 2014 Ram 1500s have a pulsating voltage coming from the controller. This would seem to allow the magnets to catch and expand the brakes. Granted, it was only a max of 1.2 varying down to .02 at times. Checking into this situation further it seems to be a common problem while Ram does not want to acknowledge the problem. Someone on another forum said to put a 12 volt light bulb in the blue trailer brake line as a resistor to drop that pulsating voltage before it gets to the brake magnets.
The light might help with the pulsating but it will also draw current when the brakes are fully engaged. Have you tried setting the controllers to a less aggressive setting?
