I have a 1993 Chevy Suburban 4WD with dual A/C. It shows low voltage on the gauge most of the time, but particularly when idling at red lights or heavy traffic and particularly when it is hot outside. A/C makes the problem worse, but does not appear to be the root problem. I have replaced the battery and alternator with no improvement. Truck has never failed to start. This condition has been going on for several years.
have the same problem?
