Silverado Voltage Gauge High

Silverado Voltage Gauge High. It's in your manual about the charging system and how it adapts its output based on demand. While these generators can fail on their own, by far the largest percentage of failures are due to the aging battery.

It is simply a range from low to high. Is it charging more because it's very cold out, or could my battery possibly be going? For gmt800's, it's not unusual for the stepper motors in the instrument panel to fail, it could easily be that the gauge itself is the.

A battery gauge reading near 19 volts. The voltage will read 15+ volts once in a while it will drop to normal 14 volts but a couple times it would drop to 12 volts and stay there until i turn of the truck and restart it and it will read 15+. The problem is, i noticed as soon as i started it back up, that the volt gauge was reading really high, like almost to 19 volts. Now i had the old alternator tested and it passed three times.
