Just got my 1970 roadrunner back from paint shop, after installing wiring harness and hooking everything back up my right turn signal won't work and the light stays on when switch is in the off position when headlights are on. The left signal works fine. Both work when headlights are off. I sanded paint off both ground connections on the radiator support, the one for the wiring harness and the one coming off the battery, I've got good ground connection, Is there another ground some where I'm missing or is my turn signal switch gone bad or do I have another problem? Any help would be greatly appreciated.
