Woody, I’ve bought the voltage meter! While car is on but not running it’s at 12.4. While running it moves to 14.2. Ive read that is normal battery power. Okay, next up...I was stopped at a light, while keeping an eye on the meter it dipped down to 12.4 and quickly back up to 13.7. The blower came on and that’s when the dip in voltage happened. Is my blower going out? Is this an easy fix?
