Electrical weirdness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Sniper X · 01-04-2010, 05:17 PM

I replaced my turn signal switch, floor dimmer switch, and the brake light switch. Everything works great but when I turn on my headlights, the right turn indicator in the cab comes on and stays on and the right turn signal doesn't flash outside the truck in front of back, and the rear tail light goes dark except for the side marker light. This is on the 1974 4x2 btw....any ideas?

Check all grounds. the headlight grounds are on the core support.

Already did that, and it is all plugged in right at the connector. I tend to think it may be a ground deal at the headlights so I will check that tonight...any other ideas while I am online?
