searched around and didn't really find what i was looking for, so here is the issue, my battery indicator light likes to flicker on and off as i am driving, and it seems to have to do with the rpms.. above about 2k rpms the light will stay off, down shift and get under the rpms coming to a stop or slower traffic, the light will flicker on and off... and also the tach bounces around a little which seems to make it flicker on and off..have cleaned all battery terminals, i have aftermarker gauges and its showing full 14ish volts charging even when the dummy light is flickering, and the tach while bouncing it will bounce a good 300-400 rpms down then back up, but the engine doesn't seem to miss a lick.. neither seem to have any effect on the running or driveability, i'd just like them to be right.. any ideas?
