my battery guage will bounce for seemingly no reacon from 12 to about 10, all lights dim and then pop right back in under a half second, but it does it under load and in nutral, thurning or straight w/ and w/o throddle ect... and has done it since i got the car its rare like 1 out of 3 times i drive it (dd) but ive replace the battery, grounded it and even switched the engine (not for this reason though)
what do ya think?

check your posative wire for the alt, or get a alt test done from a shop or something. do your int lights fliker? like the gauges go out or anything

Check to see the power connection on the back of the alternator is not loose.

The gauge should read over 14V normally, not 12V. Use a DMM to measure the battery voltage with the engine running to see if it's a bad gauge or a bigger problem.

sorry i meant 14 to 10 not 12
