Hi, I'm a new member, thanks for having me. I have a 1946 Chrysler Royal I'm working on; however, I have a problem with the instrument/dash turn signal arrow lights. I cleaned out sockets and changed all the turn signal bulbs (6 V system) on the car. When the parking brake is engaged, the turn signals on the exterior blink nice and slow, and the dash arrows are bright. When I disengage the parking brake, the turn signals on the exterior blink faster and the dash arrows dim. Any thoughts or help? Thanks, Robt
