No turn signals
Afternoon all, having an issue. 66 F100, FE 390, 3 speed manual on the floor. American autowire rewire kit and IDIDIT tilt column. So, all of a sudden no turn signals (front or rear) and all was fine yesterday. The bulbs light up, doesn't flash (left or right). Dash indicator light lights up, doesn't flash. Fuse is good. Flashers work as they should on all corners. I'm thinking the turn signal switch, but, not sure. Thoughts?
TIA, Allan

The stock configuration uses a separate flasher to control emergency blinking from the flasher that controls turn signal blinking. Can you hear the clicking of the flasher for emergency? Can you here the clicking of the flasher for turn signals?

It was the T/S Flasher, all is good.
dubya TF - speaking of the brake light switch. I had no brake light a few months ago and I had to replace the BL switch as it was the no brake light problem. I replaced it with new and purchased a second one just to have on the shelf. Fast forward 3 weeks ago - no brake lights again. I replaced again with the other new one on the shelf, no brake lights. Didn't make sense. then it dawned on me - check the fuse dummy. It was the fuse. Seems lately I'm looking for the major issue and not looking at the easy fix first (just like with the T/S flasher), I went straight to the T/S switch in the column. After comments from Gavin and TIBL, I was just gonna replace it, but first I switched the flasher from the 4 ways to the T/S and had T/S, thus the T/S flasher was bad.

Master light switch into TSS out to flasher then to brake light switch to taillights. Prolly wrong but it is def part of the deal. Are you running the pressure switch style or mechanical style switch?

I haven't had any issues but I've seen that some guys go ahead and install a ground strap for the bed to the frame just to make sure the taillights have good continuity. Mechanical switch is the way to go. Hydraulic switch is just unreliable at best.
