Default Re: trouble shooting turn signal switch

Texas,

I agree with George. Heat and smoke means the current is too much for the wiring - and will soon ruin it. (If you have ever had a tool touch both battery posts, the melted metal shows how much heat an auto electric system can produce.) If the blinker sounds weak, I would start looking for a short to ground between the switch and the blinker. Beyond this, it could be anywhere along the wires to the weak lights. On my 64, the under dash wiring insulation is getting brittle, and it has even come off one of the wires at a firewall plug - but I have not tried to fix this because it is hard to reach and is still working. I keep thinking that I should get to it while I still can, but there always seems to be something else that needs doing first.
