Driver side turn signal not working, Weird voltage issue... i think? Options

[Noahwhite2014]

SO my driver side front turn signal is acting up. Ive tried swapping bulbs, same issue. Tried swapping bulb holders, the issue persists. So i know its probably the wiring now... So i pulled out the voltmeter... Stuck the ground into the ground wire pin on the harness plug, and the positive into the left side positive pin on the harness plug (the locking mechanism is at the top, i couldn't see the wire color since it was dark) and i got 25.6V DC... This is supposed to be the DRL light on the corners. I'm not sure if it is supposed to be 25v... but i assume it shouldn't. I didnt have time to test the other side to see if it was also 25v

Then i kept the ground in the same middle pin and the positive to the right side pin on the harness, nothing happened so i assumed it was the turn signal. Popped on the turn signal and got the hyper flash since there was no bulb in. But anyway i pulled 12v off that. Couldn't really read accurately since it was going on and off so quick that the voltmeter hardly had time to read it.

So based off the voltages (assuming the 25v is correct for DRLs...) I SHOULD be getting a DRL and turn signal. BUT i only get a DRL, the turn signal shuts off the DRL light when it is supposed to flash. When the DRLs are off and i try to signal, The DRL filament will come on instead of the turn signal filament (so its dim). I forget to test the voltage on the DRL pin and the turn signal pin with the DRL's off.


Anyone had this issue before? Any ideas on what else to test?

Something somewhere is off, you shouldn't exceed the 12-14V of the car's electrical system. The only way for that to happen would be for two sources of 12V to be in series, i.e. negative to positive to negative to positive. Though in a car you have a common ground. So it sounds like the positive of the high filament is being fed into the ground for some reason.

I kind of figured that, so the 25 volts went away today, I did wash the car yesterday so some ground somewhere might be breaking and at the same time a positive 12v is shorting to the broken ground somewhere and feeding into the drl...? Idk if that makes sense but it did in my head. I'll go trace wires and clean grounds on my next day off

I'm thinking that possibly the two positives the drl and the turn signals are connecting somewhere because I can figure out why the light would turn off when receiving at least 12v to both positives and its getting a solid ground.

Electricity on paper always seems easier than what I deal with in real world situations...

Thanks for the replies guys, hopefully I can figure this out soon because right now I've got the bulb hooked up to a switch in the car with and inline fuse and that's on the battery. So to turn left I'm literally pressing a momentary switch to signal to cars in the front. I know it's probably a bad idea, but the cops here pull you over for dumb things like not using turn signals while someone flies by at 90 in a 45mph zone
