Cluster gauge Chevy 1500 problem

[1229btm]

My 95 1500 Chevy is having problem. The air bag light comes on when I accelerate, the battery gauge on the instrumen cluster maxes out, the interior and exterio lights get brighter when I accelerate. Also, their is a wining noise that comes from the alternato when I press on the accelerato. Does anyone have a clue of what this could be?

sounds like your alternator is overcharging. check to see what your voltage is at the battery when you rev up your motor to 2000 rpm. If it is going over 14.2+ volts, and I mean like 15 and up, you are overcharging the battery and all the systems that rely on balanced voltage like idiot lights will start to glow because of too much voltage on the + side just like they glow normally on the - side.

you can damage electrical components. check this right away.

Have the alternator checked for a bad regulator
