If the car is running, and you open a window, etc the lights dim and radio cuts off. It still runs, just no sound out of the factory amp.
Just discovered this.
If the car is off, and key turned to semi-on, radio and all power works FINE and will NOT cut out the radio if used while it's playing. The lights do NOT dim.
RPMS do dip when the car is running and the event happens.
Happens while driving or still. No belt slippage.
SIG REMOVED FOR THE PRUDE
