  • Electrical: Help with Turn Signal issue - 62 Lark

    62 Lark finished swapping in Chevy small block and Muncie 4 speed. Was a 6 cyl automatic car. Now I'm trying to get all the electrical working so I can take it for a test drive. Prior to the swap everything worked. The drivers side brake light may not have, I don't know for sure, but turn signals worked, or at least clicked at dash.

    Now, Headlights (high and low beam), tail lights and front marker lights work. I also put in all new bulbs to be sure. All other electrical seems to work fine. Engne runs fine, wipers, heater fan, etc all work.

    I installed a new Ford dual master cylinder with the hydraulic brake switch in line connected to original wiring. Manual brakes. I had the steering column somewhat disassembled so I could fix the horn and remove the nacelle so I could fill and paint it to look like it never had an column automatic.

    So when I stepped on the brakes the first time after having power to everything, only the passenger side brake light went on, and then only when I pressed hard on the pedal. It did it a couple more times, then it stopped going on at all. I jumpered the wires for the brake switch and again only the pass side brake light goes on. So I tested the wires to the tail lights and strangely, there is no power to the drivers side brake light at the connector (tail light works), which is after the factory splice to the pass side, yet there is power to the pass side. So there must be a problem after the factory splice, though all of that wiring is original and untouched. That should be easy enough to fix. I also am going to install a new brake light switch.

    Now to the big issue. When I move the turn signal stalk in either dierction nothing happens at all. I have checked the fuse under the dash and it's good, and I put power thru the flasher and it is good. Remember the turn signals worked prior to the engine swap. I have been testing the turn signals with the ignition in the "ON" position, but not with the engine running. It should work there, correct? I did not remove any wiring from the steering column when I was working on it. Any thoughts? I suppose the switch could be bad, but the timing is odd. Have I missed something? I see on the wiring diagram there is a neutral safety switch for automatic cars. I don't even know where that is. Could that have something to do with this problem since I swapped to a floor shifted manual trans? Any help will be appreciated. Thanks,

    Neutral safety switch is (a lot of the time) on the steering column (near the bottom where your linkage re-appears). I wouldn't think that would have anything to do with it though. HUMMMMMMMMMMMMM that's another B.T.H.O.O.M.W.W.W. (beats the hell out of me what went wrong)

      As your brake light wiring goes through the turn signal switch in the column you may have a problem there.

        I've been looking at the wiring diagram and thinking, and both the brake switch and the flasher feed into the turn signal switch. Since I can jumper the wires for the brake light switch and the brake lights go on, I'm thinking it must be a problem in the witring with the flasher since that is what appears brings to power into the turn signal switch, and the whole thing is dead. If I have power coming into the turn signal switch from the black wire feed from the flasher, but nothing going out, it would have to be the switch. I'll post what I figure out. when I test some voltages tonight.

          OK. So that was way easier than I thought. I replaced the brake switch and the pass side brake light went right on when I stepped on pedal. It turns out the ground was bad on the drivers side, so both brakes lights work perfectly now. I traced the wires for the turn signals thru the flasher and to the switch and it had power at all points. Pulled the steering wheel and found that when I had disassembled it before, I didn't put the cancelling mechanism on properly so the sliders inside the switch weren't moving when the lever moved. Put it together properly and Bingo everything works. I'm bad with electrical so I'm lucky it worked out so well.

            You did good Dougie! You traced out the circuits systematically and that is the proper way to do it.

              A few more success like this and I might actually start to like working on electrical bits..

                I'm right behind you Dougie. Gonna tackle some electrical issues my self this week-end (with the help of the Shop Manual). My good ol' boy at the garage next door boosted my 6V system with a 12V battery Doh! Now I have charging issues. Might as well do it myself.
