Voltage Gauge Reads 19 Volts

[red10]

i was wondering if any of you guys have/had this problem. I was pulling a boat for about an hour or 2 in the dark and i noticed the voltage gauge moving slowly up to 19 volts, we disconnected the boat and made no difference. I put a volt meter on the battery with it runnin and got 14.1 volts, so i'm not sure why i'm gettin 19 volts on the gauge unless it goes off of current and gives you a voltage reading instead. I forgot to mention it's a 2004 gmc sierra 5.3. Thanks,Ben

Sounds like the guage is off. I dont know if the guage can be reset or the cluster has to be changed out. The cluster should be covered to 7year/70K. The TSB is on here, ya have to search.
