rear blinker problems 61 c10
since ive had this truck its had blinker problems,..so I havnt been bothering using them,..anyways,..front blinkers work as they should,...rear pass side no blinker,..rear drivers side will blink but also makes the passenger side blink as well when its on...I don't think its the switch at the bottom of the colum due to fronts working as should...I don't think its ground as the passenger side shows life when drivers side is switched on....any ideas?

Re: rear blinker problems 61 c10
It's definitely a ground problem. Make sure the light housings are grounded to the bed and run a 12 gauge wire from the frame to the bed, make sure all surfaces where you are grounding to are scraped clean to the bare metal and use dielectric grease on the bare surfaces. When both lights blink at the same time is what happens with a poor ground, one light uses the other light circuit as a ground.

Re: rear blinker problems 61 c10
had the same problem... had me scratching my head for a couple months..
I grounded the housing to the frame.. still had the problem on occasion. my conclusion.....the housing has 2 metals that where pressed together (housing and bulb socket) maybe corrosion got inside there over the past 49 years... so ran my ground wires directly to the metal part of the bulb and never had that problem again.. good luck.

Re: rear blinker problems 61 c10
I could't get mine to work either, and my truck is new for all practical purposes.
All new components & media blasted & painted...Soldered a ground wire to the tail light housings and all works perfectly!

Re: rear blinker problems 61 c10
Check out my thread where I ad a similar problem.
http://67-72chevytrucks.com/vboard/s...d.php?t=658746 Look at post 18 from Fleetside Larry, his trouble shooting guide helped me identify the problem as the turn signal switch. Good luck, I hate Electrics! P, ![]() |
