doing rewiring of instrument panel. directional indicator never worked before. once i rewired it stays on when ignition is on and blinks when the switch is turned on. I have confirmed that green wire from "P" connection on flasher is connected to bulb. When i say "P" i am referring the center contact on the flasher unit which has its terminals shaped in a "U". The "barrel socket" that holds the bulb is grounded to the instrument panel (no insulating washer as on ignition light.) turn signal lights on outside of car work fine. all other outside and instrument panel lights work fine (with exception of low fuel light which is also always on and will be addressed in a separate post. I do not remember how it was wired before.
thanks

This might help focus things. The P connection is simple, so you may just have 12V connected to the bulb (indicator lamp) from somewhere.

Looks like problem solved. Flasher unit had a continuous circuit between the "P" and "X" terminals. A spare one I installed did not and now everything works fine. I think the continuous circuit provided power to the "X" terminal and from there to the directional indicator relay unit and then on to the directional indicator light.

Bob, I'm having same problem on my 1953 TD, which I'm assuming has similar wiring. Sounds like your flasher was defective, would you say? My new Novita EL-13 flasher works fine, except for the dash indicator light, which is new, too and works with a test 12v source. I guess I'll try another new flasher unit, perhaps different brand or model.What flasher finally worked for you?

I just used a Wagner flasher i had sitting around.
The "P" connection goes to the indicator light.
