need help trouble shooting turn signal switch

[carolina1g]

Does anyone know how to check if a signal switch is bad. My 72 F-250 signal lights were working yesterday, but now I get nothing, if I could figure out how to test it then maybe I wouldn'thave to replace it and check somewhere else for the problem. Thanks I'm new so any help would be appreciated. carolina1g

Check the fuses first. If you had a suddenly lost the blinkers, I would expect the fuse first. Should be a 14 amp (if same as '68) - see fuse box thread in the forums. (attachment not available at this time) What else is happened to the wiring? Do the emergency flashers work?

Hello bluef250, yes I checked the fuses they seem to be ok. The emergency flashers work. I checked both sides of the switch with a test light, but I only get fire when the emergency flashers are on.I'm going to check the harness plug next. THANKS

Any other rear lights out? I chased mine for a week before i figured out it was the flasher,My four ways worked and i could not figure It out . I never new my '69 had 2 flashers Also check connection comming out of steering column that is where my problem started.

I checked both flashers by switching them around.I'm going to check the wires coming out of the column next. I had to back off for a day to keep from lossing it.

Yea some times walkin a way helps loads,the wiring diagram for the 67 keith has is good for my '69. I ended up having a wire burnt in the plug if i remember right there are seven wire positions several are piggy backed on the side away from column and these are the ones I would start with .

Good luck keep us updated

Found the problem.My father had put a 78 column in the truck, so when I put a 72 clolumn back I used the 78 connector and missed the power wire.Stupid me I was checking all the connections from the horn. Live and learn.
