Another L.E.D Turn Signal Problem
Ive searched the web and this site, but cant seem to get a straight answer.
ive been running Regular bulb up front with led tail-brake-reverse lights for years (with a standard flaser 10+ years) i installed led front lights and bought one of these https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 wired up the ground and no flash/blink lights (parking) are on solid the new flasher has the same pin position as the stock one i pulled out old flasher says (HEAVY-DUTY FLASHER FUSE INPUT LEAD) new flaher says(HEAVY DUTY INPUT LEAD MUST BE FUSED) Any idea's Thanks (truck = 1970 gmc)

Re: Another L.E.D Turn Signal Problem
They make adapter for the flasher to swap polarity to make them work. LED are polarity sensitive where the regular bulbs are not. It could be the grounds also on the front turn signal housing not making good contact.

Re: Another L.E.D Turn Signal Problem
Not necessarily. They are separate circuits but I think the problem is the polarity.

Re: Another L.E.D Turn Signal Problem
So I just made some short leads to test. (Flasher is plugged in opposite) still solid no blink. This is the electronic led flasher /w ground wire

Tested. Solid leds polarity is just reverseing the pins while plunged into fuse panal right? I made some short jumper wires and switched the pins and put the flasher ground to the dimmer mounting screw. Tested. Solid leds

Re: Another L.E.D Turn Signal Problem
FIXED
ok long story short my flasher set up as follows THE HAZARDS FLASHER a electronic flasher with polerity reverser installed (with ground wire grounded) THE TURN SIGNAL FLASHER a electronic no load "reverse polerity" flasher (no ground wire) this is the original flasher i baught and tried but did not work. THE PROBLEM = becouse i did not have a hazard flasher i didn't realize my hazard button was set to on of course the blinkers didn't blink. i just tested this theory and thats what it was. You know sometimes my blonde hair makes me not think clearly lol.

In my defence I did mention I'd never had a hazard flasher installed. No one ever mentioned make sure your hazard button isn't on. Lol I sure did fill like a ra-tard when I figured that out

Re: Another L.E.D Turn Signal Problem
That's what my post was for when I went out and checked mine. I had thought maybe this was it.
We have all been there. Don't feel bad it's just part of the game.
