I installed led flasher when I put on a stinger. The flashers were installed with resisters. The flasher works great however only one of the parking lights doesn't work. I replaced the driver side parking light thinking I blew the bulb. The bulb was good but I replaced it anyway. I also tried bridging the good parking light to the bad one hoping I could get power to it. It still doesn't work. I think there is a ground issue but I am not sure. Anyone have any suggestions?

 

You sure you did not mess up the wiring when you added your LED flasher resistor? Left out a ground wire? Made a poor connection to ground?
Tested if you have power to the connector? Got ground to the connector?
Got a multi-meter? If not harbor Freight is your friend.

 

There is no ground wire on the flashers? Just two wires.

 

The flasher is not your problem, is it?
So let's look at your parking lights.
Got a multi-meter?

 

Something is missing in this story Like just what your working on.

Besides the flasher what else did you add .

Since the turn signals and hazard lights are on a different circuit then the parking lights they should not be effected .

So the LED flasher being added should not effect anything on the parking light circuit.

Two different circuits unless you added a new led light with turn signal and marker light they don`t share a common ground except in the tail light.

Even a Fluke does not help if you don`t know where to put the probes.

 

I didn't do anything else with the parking lights. When I got the truck random wires were everywhere so I clean those up. Wires were spliced in on the parking lights and to hocked up to some fog lights. I cut those off and it worked fine for a while. I am going to try the Fluke today.

 

OK I have figured out what was wrong. I broke the Fluke out and learned for one the drivers side parking light has no power and is dead. I ran wires from passengers side parking light to the drivers side and I had power but the light didn't work. I started to play around with the connector and there was power but no light, the bulb was good and not burnt. So I took the wire on the bulb and twisted it to touch the connector and presto it worked. So moral of the story the connector contacts were to wide to make contact with the bulb! We are good to go! Now to get the back light to work on the AC/heat face plate!
