rgreskoviak Posted January 27, 2021 Report Posted January 27, 2021 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 Quote
kencombs Posted January 27, 2021 Report Posted January 27, 2021 Does your parking brake have a 'brake on' warning light? If so that may be providing a ground for the entire panel due to other poor connections. Quote
rgreskoviak Posted January 28, 2021 Author Report Posted January 28, 2021 Ken, thank you; yes it has a handbrake warning light that's activated when the ignition is on and the brake is engaged. I'll check and clean all connections and switches. Thanks Quote
Marcel Backs Posted January 29, 2021 Report Posted January 29, 2021 If it's original wiring, check for past splices into the harness under the dash and at each of the tail lights. Black electrical tape "junctions" if any exist should be checked for faults. If you have a multimeter, make sure live side of any of your light circuits read high impedance to a known good ground with battery disconnected (always do impedance tests on de energized circuits). Check to make sure that all light socket bodies read zero ohms to ground. Check wiring thoroughly for insulation breakdown. Make sure that any previously joined wires are either soldered or crimped and properly isolated. All the Best, M Quote
rgreskoviak Posted January 31, 2021 Author Report Posted January 31, 2021 Mr. Backs, Thank you for the advice sir; I started with checking the grounds and found that the ground for the dash assembly which is located under the Generator regulator was corroded. Cleaned up and it's working fine. Thank you, Robt 3 Quote
Tooljunkie Posted January 31, 2021 Report Posted January 31, 2021 As soon as you tensioned up the parking brake you made a good ground between chassis and body. Good you found the loose ground. Quote
Marcel Backs Posted January 31, 2021 Report Posted January 31, 2021 I forgot to mention that an external tooth lock washer and some dialectric grease at the connection will ensure a reliable ground for a long time. From what I see in the pictures your wiring looks to be in a nice state of preservation as well as the rest of the car. All the best and glad I could help a neighbour to the south! Quote
rgreskoviak Posted January 31, 2021 Author Report Posted January 31, 2021 Tooth washer in place sir; took apart and put a "pinch" of dielectric grease! Thanks! Quote
