Best suggestion would be to find the appropriate forum. You posted this in the 2009+ truck section.

Scan down a bit and you will find what you are looking for.

standard problem with these year trucks. the gauge sticks in the off position. once started, give the top of the dash a smack rite above the volt gauge. the gauge should pop rite up to charge.

rikard is gaining momentum as a positive member of FTE.
Use a digital volt meter and measure what the voltage is at the battery with the engine off. It should be 12.6 to 12.9 volts DC. Start the engine. The voltage should jump up to 13.6 volts or better. The alternator is designed to produce enough to keep the voltage at this level with all of the electrical on.
Happy New Year

Yes, it is a problem with these clusters.
