Battery light flickering issue for about a week. I know its a charging problem from reading some other posts.
Had 2 rebuilt alternators put on and its still doing the same thing. Battery was recharged and is holding power. so the battery is not the problem.

Any suggestions of what else might be causing this.? Could there be something wrong with the ECU or other wiring/electrical?

Also had some stereo grounding problems before all this stated happening but the stereo is re-grounded.

Could be a grounding issue not with the stereo but with the wiring in general or could be something not even close who knows on that one

Check all the chassis grounds FIRST. It's a known issue that some can get loose. This screws up the whole electrical system.

yeah the set behind the passenger front tire let loose on me awhile back but mine was way worse than a flickering battery light.......I believe there are about 6 or 7 grounds there all on the same bolt.

Since I had a bad experience with my garage, check to ensure that the alternator was installed properly. If it is, then check the grounds as stated above.
