1972 ford crazy lights-help

[preacher]

Just got this truck and the headlight switch has been replaced about 2 years ago.Right side blinkers were inop. Front turn bulb was rusted and I cleaned socket and replaced bulb.Right rear has a good bulb but no juice. Left side blinkers work until you turn the headlights on.With headlights on no blinkers work. Any suggestions?

The lights not working with the headlights on is a good sign of a bad ground connection in one of the turn bulbs, be sure the ground wire is connected on all of them and the bulb is making good contact as well.
The right blinker could be the Turn Signal Switch (TSS) you can test it with a test light at the column to see if you are getting power out of it to the lights. You can use this as a guide for testing the wires.

Thanks for the help. I will take my ohmmeter home this weekend and see what is up. God bless you.

That sounds almost EXACTLY what's going on with my 70
