I had a turn signal switch bad on the contacts on one side. Remove the switch and check across the contacts with an ohm meter to verify. Perhaps can clean the wiper contatcs to repair ??

either one of the right front or rear marker assemblies has a hot lead plugged into a ground, or one of the wires in the column chunk is rubbing and grounded. Try disconnecting one assembly at a time and see if the em flashers begin to work again. If with both front and rear assemblies completely disconnected, the em flashers still do not work, a wire is melted or the column turn signal switch wire is grounded and or burned

Thank you George. I'll start the process soon. I suspect the steering column as my son says he saw a puff of smoke.... I did not.
To clarify, would what you describe cause the emergency flashers to not work at all?
and the brake lights?
Thanks,

All the wires for the turnsignals should terminate at the 4-way flasher switch. I wouldn't open up the turnsignal stalk on the steering wheel until you verify the wires to the right side lights are ok.

BTW, the flasher flashes both right and left turnsignal bulbs. There's only one wire from the flasher to the 4-way switch and turnsignal handle. If the flasher works for one side it will work for the other if the wiring is ok.

Is this something that just started or has it always been like this?

This just started. I have found a green and black short to ground. It is the wire to the front right turn signal.

I have bypassed by running a new wire around from right front housing to 4 way switch Now the emergency flashers all work.

Running lights all work, but right side blinkers still do not work. I see no power on R of emergency switch with right blinkers on.

Also now no lights for either side on tach.

I do not know how to get at the turn signal switch.. this is a 1970..

Where is this wire that is shorted to ground? How did you determine it was shorted? Did you remove the right side bulbs before testing? I buzzed it end to end and it was short to ground. Yes, I unplugged both ends, still short to ground.



So now all 4 corners turnsignals work? All four corners emergency lights work, yes. Right side blinkers and dash indicators are dead.



So you measure voltage with left side blinkers but not right side blinkers? Yes. On the emergency switch, L and R



You should see something if the left side turnsignals are working. Check the bulbs just to make sure they work. You can also check them by removing the common wire between the 2 bulbs and connect either one to ground and try the 4-way flasher.



I believe you start with removing the steering wheel, then continue to dig into the other components there until you reach the turnsignal stalk. It could be that the shorted wire affected the turnsignal contacts or wires.
