Thread: 911ep ls12 problem

I received a 911EP LS12 blue Friday from a person on here and I've had problems from the get go with it. I went to 911EP's site for wiring instructions before I did anything so everyone knows. When it arrived it wouldn't work at all and suddenly it popped on. Now it either turns on, doesn't turn on at all or between 2 and 3 lights come on and they do nothing. It takes several flips of the switch to get it to work again, but when you shut it off, it starts with the problems all over again. Any advice? God knows this thing has NO manufacture date on it and it has 3 pattern wires and 2 grounds and a positive red wire. I'm done with this useless light and i'm out 65 bucks, a pissed wife and a rear light that I can not afford to replace.

Is this the older or newer style? A picture would be helpful, of the light and of the wiring harness you have. I ran into a similar issue once before. It was the newer style, switched version, that had the cig plug cut off of it. There was a Red (+) a ground (-) a green (+) and a clear wire (+). If I remember correctly the Green activated the light, the clear changed the pattern, and you had to always have power going to the positive and negative, or it would goof up something fierce.


Let me know..

Ultimate D is right, the +12 volt wire must be energized at all times. If this doesn't remedy the issue the problem likely is the circuit board. The previous models would allow you to energize the +12 and pattern activation together.

I think I have it working now. I did have it working fine until I disconnected the energized 12v wire to connect it to the fuse and it acted up again until I disconnected the negative wire let it sit for 20 seconds and reconnected and it started working right again. I have it all i9n and working now so, who wants video lmao. Might as well get it before it acts up again :P

I have to laugh. It keeps me from ragging lol. The wiring set up on this thing is stupid.

I have the smae problem with my LS12's. They will work fine for awhile then they act up again. I am thinking about replacing them. They are nice lights when they work properly

It had a loose wire inside. It's been working fine sense the fix.
