high voltage?

my 1988 pontiac bonneville says on my dash voltage gauge i have 16 volts almost to the red line. but when i put a multimeter on the battery it reads about 14 volts with the engine running and 12.5 with the engine off. any suggestions as to what i can do next? by the way this is a 3800 engine.

Get a schematic for the gauge system. If you've verified it with a multimeter, the gauge or sensing wire is probably bad. Dash gauges are woefully optimistic and not worth a darn for accuracy anyhow
