Can Poorly Installed Breakaway Battery Kit Cause Brake Controller to see Disconnected Trailer

Hey Jerry,

If your breakaway kit isn't hooked up properly I suppose it could give that "trailer disconnected" code on your brake controller, but it would have to be that the wiring going to your brakes is disconnected on the circuit somewhere for that to happen.

I think you have some damaged wiring or a bad connection somewhere that needs to be fixed - this could even be where your trailer 7-Way plugs into your vehicle 7-Way socket.

I'm attaching a wiring diagram that can be used for all breakaway battery kits that you can use as a reference to check how you've connected everything.
