Wiring for turn signal
I am trying to diagnose my turn signal and brake light issues on my 85 F250. I have a test light and am trying to see if power is actually getting to my turn signal switch. Should one of the wires in the 11 prong u shaped connector be hot. I’m not getting anything on the test light- Hayden simpson

Turn Signal problems
So my 85 F250 has been having turn signal issues. The turn signals will slow down and stop working. Then after a little while they work again. I have already replaced the flasher and turn signal assembly because it was not returning. My guess is I have a loose connection or ground somewhere...- Hayden simpson
