All Lights Strobing/Flickering..

[Dru]

All my dash lights, headlights, tailights, and interior lights "strobe" or "flicker" when my car is running idle. I just replaced the alternator a year ago with a remanufactered alternator. When I accelerate, the flickering "speeds up" with the idle. Do I need to replace my alternator again, or is it another problem? Any help is greatly appreciated!

I replaced my alternator and it kept doing it. I then changed my battery and terminals and it fixed the dimming. It acted like a slow strobe or like the lights would fade bright to dim. Give it a try. Worked in my case.

I would keep it. A lot of people pay good money for that.
Clean your terminals, Check all of your ground connections coming off the battery, unbolt the wires where they connect to the body and clean and replace. make sure your positive lead to the alternator is clean, and healthy, unbolt the pos wire from the alternator clean, and replace.
It's most likley a weak ground.
