Electrical Question

I have a Mopar with a Painless wiring kit. Been on the road almost flawlessly for 3 years, when suddenly, every time I depress the brake pedal, the front turn signals illuminate. Now I have discovered that I have no turn signals at all, no flasher, no lights at all, front or rear in turn signal mode. Rear brake lights work to perfection, except in turn signal mode. Emergency flashers don't work either! I haven't begun to work on it yet, I'll wait for you guys to tell me where I should begin. I hope it's something simple, thanks in advance for your help, you guys are amazing. The Inspector

Check the brake pedal, it sounds like it rubbed a bare spot on a wire in the light circuit.the brake pedal is acting like a bad switch. Thats my two cents.

Turn signal switch is the only place where the brake light circuit and turnsignals could "cross" paths in order for the front turnsignals to come on when you step on the brake pedal.


This is assuming that the fillement in the front bulbs is the brighter one and not the dimmer parklight fillement.


If it is the dimmer fillement, then you would have a bad ground in the rear lighting circuit. Causing it to feed back through the taillight circuit, which is connected to the front parklight circuit by way of the headlight switch.

Have you replace any bulbs lately? It is possible to force a single filiment bulb into a duel socket and get feed across the brakes to the light circuit.

I would look at the fourway flasher switch, if that is shorted it will cause the brake lights and turn signals to flash all the lights.

check all bulbs first sometimes one side will burn out and the filament will fall on the other, have you pulling your hair out. Then check and make sure all grounds are good tight and clean and if that doesn''t fix it go to turnsignal switch in column. hope some of this helps RED

As you can see from above, there are many different things that could go wrong. I do like all responses, especially cheyenne's and blown 29. I would start with looking under the dash with a strong flashlight. Study what you are seeing because things look different upside down!
Like blown29 suggested, the brake pedal could be rubbing on some wires that have moved around. This could make a big difference with the Painless kit, depending on what was done with the "spare wires" terminated at the fuse panel itself. If you see no problems, continue with the easiest thing to check.
If it isn't something simple, write down what you have done, so you can try and draw logical conclusions, and you don't do the same thing 3 - 4 times!!

Hope it helps, lLet us know how you make out.

my two cents worth.... no one has asked what column you are using. If it has a 4-way flashed switch on the column it may have gotten depressed (turned on) this will cause the parking lights to activate when the brakes pedal is depressed as well as stop the turn signals from functioning. cure is to simply pull the switch 'out' sounds overly simple but you aren't the first person to have this happen without realizing that it did. Its worth looking at before taking something apart

Thanks all........I've been really busy at work, but we went to a local cruise in Friday night. Before we left i checked my ground at the rear lights. they seemed to be OK, but I loosened the connections and tightened them again. I had no turn signals, but the front lights didn't come on when the brakes were applied. SO, we ran to the cruise in in the rocking chair so as to be safe, and on the way back home the left turn signal light came on and stayed on. i suppose that means something is loose someplace..man I hate wiring. My front turn signals are single filament, so that rules out some of the comments. I'll get back to it one night this week, and keep youall posted. Thanks for the help again, i really appreciate it.

You have a feed back somewhere and I have seen that happen with bulbs and a circuit with a blown fuse.I would take a known good bulb and thru trial and elimation replace each bulb until you have either checked all or fixed.test all fuses with test light.

I have a question for all of you. When I fill my gas tank the gas guage reads at most 3/4. When I step on the brake the gas guage reads 1/2. When I have about a half tank and step on the brake the guage reads 1/4. Where do I start looking?

Sounds like a bad ground. Make up a jumper wire with alligator clips. Put one end on the negative battery terminal and the other on the tank and see if it's fixed. You can do the same to the tail lights to test.

Dixie, That sounds like a bad bulb, or make sure hes changing the correct flasher,

Tychoochoo, Is the fuel gage the only gauge effected, do any of the other gauges move when you hit the brakes, Sounds like you might have to many grounds tied into one wire, I think a poor body ground might do that to,

I found an issue the other day that may help some of you guys, I had a colum that would shock you if you turned on the blinker, Also the horn would blow when you turned........The screw head on the blinker switch would touch the contact plate for the horn, I grinded down the screw head and re installed it and it was fine.

Leon, The only guage that moves is the fuel. I did notice that I have a wire coming from the top of the fuel tank (I think) it's hard to see. This wire connects to a bolt on my license plate frame. I thought this was odd but left it alone. The license plate frome is the one that has the third brake lite in it. I don't know if this is a ground or something else. Alot of what I have found with wireing is not color coded. I have Classic Vintage Guages. Thanks, Tommy

Run a ground wire from your sending unit to the frame. Make sure you clean the paint off the frame where you attach it.

I have to cut away the exhaust to drop the tank so I can get at the sending unit. Whoever did the exhaust welded everything in place with no place to seperate. I have a feeling the wire that's attached to the license plate frame might be the ground. I have a poly tank.

I had a poor ground between body and engine and frame. When running and alternator putting out 14 volts, temperature went to 200 and gas guage went to full. Ran new wires, cleaned up where they were secured, and now car runs cool--still burns gas though. lol
