  • Turn Signals

    My turn signals do nothing. I've replaced the turn signal switch, the turn signal relay and NADA. Also, just to add fuel to the fire, the emergency flashers work only on the right side, the wipers won't work and the washer motor doesn't either. Most of this says "disconnected ground" to me. Anyone have any suggestions?

    Your hazard switch could be the problem with the turn signals as well as the left side hazard lights. You could bypass the hazard switch to troubleshoot the turn signals by disconnecting the multi-pin connector and somehow jump the green and light green/slate wires on the harness side of the plug. If one or both turn signals work, you will know the hazard switch

    It could be the grounds for the wipers and washer. check the Cabin Ground Point shown on page 2 of this pdf. TR6 Ground Points.pdf

    Check back in with what you find..

      Thanks for the Ground Points.pdf. I will find it helpful too, I'm sure.

    OK, an update. I ohmed out the 30A fuse. It ohmed out fine, BUT close examination revealed that there was exposure to electrical over stress (EOS). I replaced the fuse and, like magic everything that wasn't working (wipers, fuel/temp gauge, back up lights, washer) is now working. HOWEVER, I still have zippo turn signals and no flashers on the driver's side. The flasher switch is new, so my best guess is the flasher relay. Anybody got any better ideas?

      I know that the AAW manual is very dismissive of the OE flasher switch and they even provide a switch with their harness which they strongly suggest that you use.

        Had you mentioned that nothing on the green fuse circuit was working you would have received a different reply from me.

        So I take it you didn't try jumping the multi-pin connector as I suggested? No problem. Using your multimeter, check for voltage with the ignition switch on and the hazard switch off at the "B" terminal (light green/slate wire) on the turn signal flasher in the passenger's foot well. If you have no voltage, it still points to the hazard switch. If you have voltage, it might be miswiring of the turn signal switch.

        The flasher switch is new, so my best guess is the flasher relay.
        I presume you mean the flasher? There is no flasher relay as on early cars. If the hazard lights work on the right side, that indicates the flasher is good. The problem could still be in the hazard switch or the turn signal switch wiring. There are other possibilities, but they are less likely.

        Do your parking lights work in the front?

        Let us know what you find.

          OK, ANOTHER update! Loose connectors were the driver's side emergency flasher problem. I'm now down to just 3 others: 1) still no turn signals and it doesn't make sense. The only thing that hasn't been replaced is the turn signal flasher on the passenger bulk head. Moss doesn't have them, TRF does. That's pretty much my last idea. 2) The ignition light (which functioned fine) suddenly doesn't light up. (?) 3) the high beam switch turns the beams off. Why?

            FWIW, I've found the flasher units from the usual suspects to be NFG.

            What works is the Signal Stat 175 ( NOS vintage ) readily available on ebay for about $15. I just installed one on my concourse car to match that in my driver which has been working for the last 22 years.

              Are these the same?



              Did you check for voltage at the turn signal flasher terminal "B"?

              You can jump the two wires at the flasher and still troubleshoot the system. If all is good, the lights will come on, just won't flash.

                I had the same problem on my '71; it was/is a chore to trace the circuit. It was easier w/dash partially removed.
                Removed Emergency Flasher unit (rocker-style), both the emergency circuit and turn signal circuit run thru this switch...inside it was in 3 pieces; repair was not possible, replacement seems unobtainable.
                My solution: I connected turn signal wires (hard-wired them) and they work as required. I connected emergency circuit with remote in-line rocker below radio; 4-way works when switch is on.
                My car's a driver, so the only thing out of sync is an extra toggle switch. My two cents, for what it's worth.
