Need some minor electrical help

OK, I have what I think should be a fairly easy fix if I wasn't such a dufus when it comes to electrical. I will explain as best as I can.

My 48 Plymouth coupe has been converted to 12 Volts and rewired by someone else using an 18 circuit EZ Wire harness. I have added Technostalgia brake/tail lights and a cheap Speedway turn signal switch.

Ok, everything was working fine after the car was rewired, then the brake lights quit working. So I changed my hydraulic brake switch and went with a low pressure version from Sache Rod Shop. That did not fix the problem, turn lights and taillights worked but still no brake lights. Since all the wiring to the rear goes through the turn signal switch and the switch was getting a little loose anyway, I purchased a new heavy duty switch from Speedway.

Installed the new switch today and still having issues. Now the taillights, emergency flashers (which I didn't have with the other switch) and p***enger side turn signals work (both front and rear). The driver side turn signal just come on and stay on in the rear with no flashing. The front signal on the drivers side does nothing at all. Checked the bulb and it is good. Still no brake lights.

Again I think this is probably an easy fix for someone with a meter and a little know how with electrical. That is just not me.

Anybody in the Dallas area who would be willing to take a look at this thing to see if they can help me figure this out? If so send me a PM and I can bring the car to you along with your favorite beverage, lunch, dinner what ever.

 

hmm...as far as the blinkers staying on...you may want to check your flasher maybe? its the little round silver cylinder under the dash that was connected to the wiring. i would still think that it would have something to do with the brake pedal pressure switch not making a good contact to have the brake lights come up? without seeing it its kinda hard to diagnose, but i hope you find out that the hell it ends up being amigo

 

Sounds like a bad ground to me.

 

Check to see if you have power going into the brake light switch.

 

Guys thanks for the input.

I don't think it is the flasher since the hazards and p***enger side turn signals work and flash properly.

I would think that if it were a grounding issue that the tail lights and hazards would not work on the drivers side either. But like I said I am no electrical genius so I may be all wet.

 

Like rustyford40 said, check for power at the brake switch. First check the fuse they are typically not the same as the signal fuse, even though they use the same bulb filament. If the fuse is good, you can use a volt meter or a 12v light with pig tails to see if you have power to the switch. You should have voltage between one of the terminals that plugs onto the switch and ground ........ you can also try just jumping a wire across the plug terminals and see if the brake lights come on. If they do, then you definitely have power and a bad brake switch. If they don't come on, you'll still need to check for power, as noted earlier. If no power, you'll have to start tracing it back toward the power source.

If you have power, then first check the brake switch. Test it for continuity with a cheap light-up circuit continuity tester, or an ohm meter. The light should light, and/or the needle should move on the ohm meter, when the brakes are applied.

If you have power and a working brake switch, then it must be in the wiring at the turn signal switch, and I would have to see that to help any further.

 

What I was thinking. You can't have too many grounds.

 

let me know if you got it fixed, if not, your right down the road from me I'll come help

 

Actually,grounding issue will cause them to not blink,and a short will cause them to blink rapidly.

 

Just what I was thinking, except to many grounds in your coffee isn't good.........

 

1.check the fuse
2. check to see if you have power to the break switch if you do take a wire strip both ends and the 2 leads that go to the switch and see if you have brake light if you the bad break switch
3. if still no lights then problem is where the wire that goes to your turn signal
hope this helps if you like shoot me a nuumber and best time to call here my email royrcastillo@yahoo.com by the way I rewire cars you can check out my work at this site socalconcepts.webs.com good luck let me know what happens Roy

 

That techstalga piece, by any chance is it where you used LED lights? And the gizmo is a converter that adds a load to the circuit for the flashers? Try to byp*** it and temp some regular lamps and sockets. All this ***umes LED.
