Should Red Dot Appear on Reese Pilot Brake Controller With Brake Pedal when Trailer Not Connected

Question:

When I push the manual slide when the trailer is not hooked up the dot does appear however when I step on the break… Is not a pair I had thought the dog was supposed to appear when you step on the break and trailer not connected?

When the brakes are applied with the Brake Controller part # 80550 installed the dot should appear on the display. When the dot does not appear in this situation the issue is that the red wire of the controller is not connected to a circuit that sees 12 volts of power with the brakes applied. You need to verify first that the red wire is making a solid connection and then that the circuit has 12 volts when the brakes are applied.
