My '53 had a Dietz 111 4-wire turn signal in the truck that wasn't working. 3 wires went to the turn mechanism and 1 wire to the indicator light. The truck has separate turn lights.

The old cloth wiring was a mess so I pulled it to clean it up. I've seen some different wiring diagrams so I just need a confirmation. Using a 3 pin 6V flasher it was wired: Fused 6V to pin (X), pin (L) to B stud on turn mechanism and pin (P) to the light. Does that sound correct?

Does it need grounded through the turn signal body assembly to the steering column?

I'm not sure which pin you need to go to on the switch but the L terminal does go to the switch. You have it right.

The switch housing needs to be grounded for the pilot light to work.

Thanks Cletis. I wired it back up with the L pin to the common B pin on the signal. I made sure that there was good contact to the steering column, new flasher and still nothing. I finally thought to check one of the signal bulbs, cleaned the contacts and it worked! I guess it wasn't making a complete circuit.
