Ok, here is the strange deal. My passengers side turn signal and brake light are not working (same filament) but the one that comes on with your headlights (other dimmer filament) works. I am getting ~10 volts out of the socket. No matter how I try and adjust the contacts inside the socket it still wont work. It suddenly started happening and I thought the bulb was bad but that wasnt it (replaced it). Any ideas? This one has confused me.

Hey Tim,
Not sure if this will help, but Ashley's '66 coupe started having turn signal/light problems and found out that the light wiring actually runs thru the floor mounted headlight dimmer switch. We replaced that and then everything started working fine. Don't know if this will fix your problem, but it's worth checking.

Tim,
Make sure the black ground wire that is normally is attached to the taillight housing is making good contact.

It could also be the turn signal switch.

I think its something with the socket. I am getting ~10V to the passengers side rear socket when I push the brake pedal down and also getting volts when the turn signal is on. I made sure it wasnt a bad ground by connecting a wire from the body to the taillight housing with no luck. It shouldnt be the turn signal switch as I am getting power back there and if it is I am gonna shoot someone (this is already my second replacement, the first one I installed something was wrong with it and it started smoking and never worked but the 2nd replacement did work). I dont see anyone selling the taillight socket (mine has the push on connector not the pigtails) so I will see what I can find at an auto parts store. Until then, if I get pulled over I am gonna plead ignorance .

Tim you can have voltage without amperage, a voltmeter puts no load on the circut so the power can read good and not have enough poop to light the high load of a bulb. Pull the wires off inside the trunk and hook the bulb farm style to test the circut, if it works and the socket is at fault go to just about any electronic supply store and they have the socket guts including spring you just need to add your conector to. If it don't work shoot someone

Ok, its time to shoot someone . I pulled the plug on the socket on the passengers side and ran it over to the drivers side and it was giving me the same results (works when headlights are on, no brake or turn signals) so its a wiring problem somewhere . But its only affecting the passengers side. Bah, time to put my knowledge to use and debug it.

I would suspect the "new can't be anything wrong with it" turn signal switch

Sac Mustang is gonna have this turnsignal switch through their window! What a POS, the original piece lasted 32+ years and this one only lasted umm 2 years (the first lasted 4 seconds)
