I've been looking on here and can't seem to find the answer I'm looking for. I have an 06 sel that's been having issues with the lights, at idle all the lights in the car pulsate (for lack of a better word) they rapidly dim and brighten, the idle is also rough. when it first started the alternator also failed so I attributed it to that, I have now installed 3 (from a scrap yard) and I'm still having the issue. If I unplug the alternator and start the car it runs fine and the lights don't pulsate. If I unhook the battery and run off the alternator only the lights pulsate worse. So I guess my question is if I buy a reman alternator will this problem go away or is it something totally different.
