Hey guys having fun with this 1964 Ford F-100 Custom cab.. Anyway troubleshooting the tail light. Fixed the connector but when I turn on the turn signal its real dim. The running light is Ok. Bulbs good. I noticed that the turn signal arm on the steering works but seems weaker when flashing compared to the other signal. Could the Turn signal cam be a issue? I am thinking a ground issue? Any thoughts

 

check brake light if it is dim also, look for a bad ground.

 

Thanks will do! I think also its a ground issue... The original wiring is in place so who knows Ha!
