Wiring confusion. - 05/02/14 10:13 PM
The car:'69 Super Bee. New wiring front to back. New light bulbs. The problem: passenger side brake/flasher/turn signal lights don't work. Tail lights do. The drivers side works fine.
I took a Dremel tool and a sanding wheel and hit the inside of the taillight housings, thinking bad ground. No change. The symptoms say to me bad ground. I can see a turn signal switch being bad, but that doesn't explain why the brake lights and flashers don't work... The new harness has spade terminals on it, I'm thinking about building another ground harness to see if that helps. Just picking your brain to see if anyone else can come up with any ideas...
Thanks..

they do use the same connection into the turn signal switch/harness. I'd still look there- front uses a different connection than the rear does to the turn switch.

Have someone while holding brake pedal down, jiggle the turn sig lever a bit while looking at tailight. If it blinks on and off, chances are there is a turn sig switch problem.

Is the passenger tail light housing grounded to the body? You mentioned that you hit the inside with a dremel tool, for the socket? Try hooking a jumper wire to the metal socket with it all plugged in and run it to a known good ground and see it they work then.

I had to run an a ground wire from both housings to body to get my lights to shine bright. Before I did this they grounded through my dash reverse light(4 speed).

The brake/turn/flashers all use the same large filament in the dual filament 1157 bulb so there is (1) wire going rearward to the (1) filament on the pass side (& one for the DR side). I would seperate the dangling electrical connector for the brake/TS lights under the column & jump fire to the (1) wire for them. No go? then jump fire to that wire under the DR kick panel. No go? going rearward there's a connector or two under the carpet & same thing seperate/jump fire to check each one till you get fire/continuity to the rear pass socket & check that the bulb filament(s)is good. that the bulb base contact to the socket is good. On the ground side that the bulb case is making contact with the socket. that the socket (as said) has continuity to the frame. If all good (& you can shortcut that procedure as needed) then the problem is in the TS switch/harness because it is recieving fire from the brake pedal switch (the white hot in wire) and directing it to the DR brake large filament & it should be firing both sides at the same time (with the stalk in neutral)

I'm not getting any juice to the connection at the kick panel. I started forward, but I haven't got under the dash yet. The turn signal switch looks to be pretty expensive, so I'm going to try to track it down some more before I spend the green.

Expensive & a pain to swap in the column so definitely ohm it out before you order anything. I'd get on the col half of the dangling connector & see what you get for continuities.

Will do. I have to get under that and put in some bulbs for the dash. So while I'm there...

I did some thinking and just spitballing here... If the right side front signal works, would that mean the switch isn't bad? It clearly runs something. Maybe I'm not up to snuff on what is connected where, but the flasher/turn signal and brake switches are all interconnected somewhere? Everything else works except for the right side rear turn signal/flasher/brake lights. I'm not grasping something here.

The wiring to the front and rear side to side splits in the turn signal switch. Just because some of the lights works doesn't mean the switch is good. Everything is interconnected in the turn signal switch. I have fixed plenty of these kinds of problems with a new turn signal switch CAM available at most parts stores. Be sure to read and follow the instructions to the letter because you will need to trim the wire whiskers on the new cam exactly like the original ones.

That's what I was wondering. That explains it. The cam seems good, but a trip inside the column is coming, it seems.

I'm still checking wires and ohms and playing with the test light. But it seems the switch is bad.

Can you swap the wires side for side and see if you have the reverse situation?
Not sure but my RR did the same thing and it was the blinker switch in the column. I changed that out and all my lights work Good now.
I messed with wires, grounds, bulbs, etc till I finally figured it out.
If I turned on the opposite side blinker then the bad side lights would work like normal.

Mine just straight up doesn't work. I pulled the cancelling cam out and jumped things and read things. It looks like the switch. I'll get back to it this weekend, I hope. I have a little over a week to get the little things worked out for Columbus.
