Should a Reese Pilot Brake Controller Show a Decimal Point When Trailer Brakes are Applied
Question:
The red dot should light up when key is on position and then letter C lights up when trailer is connected, digital readout to adjust brake control. Mine always did that until lately now nothing lights up with key on, dot comes on only when brake is applied. No digital readout at all.

Actually the decimal point of the Reese brake controller part # 80550 that you have should only come on when the manual slide or vehicle brakes are applied without a trailer connected. It sounds like yours is working properly.
Have you tried connecting a trailer to the tow vehicle to see what happens? If it doesn't show a connection most likely the problem is corrosion on the trailer connector of the vehicle or trailer.

Does the decimal light go off eventually or does it stay on constantly and won't that run the battery down
