[AT] A question for the electrical wizards

[Will Powell]

After eliminating the ground issues, if you still have turn signal issues, take a look at the turn signal switch. I have owned two trucks, 62 GMC and presently 1985 F250 Diesel. Both had one of the turn signals go dead. After hours of testing... In both cases it was the connection at the turn signal switch. Specifically the little rivets that attach the wires to the switch.. Somehow the connection at the rivet (in my cases) fails to connect... A re-crimp or solder fixed the problem for me...

Try to find the body ground. Some ground with a small wire from the 
batt cable to the body at the radiator support. If you find the body 
lap seam on the firewall, drill a hole through it and grind down to bare 
metal. Then run a 4 gauge wire from that to the graound side of the 
battery. If you have a star type locking washer, put it between the 
body and the ground cable. I have done this on several 50 year old 
trucks and it improves even the old six volt ones. It is amazing how 
much better the heater works with one of these cable this way...
