Check the frame grounds too. I had a similar problem and found it was the rear tail light frame ground. The rear lights ground to the bracket which grounds to the box which grounds to the frame which should ground to your neg battery terminal. Make sure it is all connected. It will drive you nuts trying the chase down a ground problem if you don't make sure all grounds are tight and good. Good Luck

Yes i still had the problem before i changed the turnsignal switch. I had found another problem with the lights that when you turned on the headlights the right turn signal would flash. The new turn signal switch took care of that but not my other problems. I'm pretty sure it's gotta be some type of ground in the cab because at the harness in the firewall where it goes to the back I get the blinking volts at the dark green wire which is ps rear turnsignal but also the brown which is the headlights circuit. I traced the brown wire back and it plugs into the headlight switch . i unplugged that there and they still blink. I then checked for continuity between the dark green and brown wires to see if they were cut and touching somewhere but i didn't get any continuity

I just looked on my 72 there is a ground up by the voltage reg. also. Not saying this will find your prob. but unplug the rear lights at the plug in the back and then see if you still have the prob.

the front lights flash too and so do the dash lights.I was just out playing with it cleaning up my grounds in back and threw the multimeter on it and it gets power like that. What i'm looking at now is 2 small boxes on the ds firewall right by where the wiring mount is on the back of the fuse box. theres one brown wire that runs itnto 2 what appear to be black ones. when i unplug the clip the front 2 light markers go off. Could all of the lights be run through these 2 mysterious boxes and what the hell are they? I look in my haynes manual and there not covered.
