You have a fuse or circuit breaker in the charge wire right? Several here have reported issues with the chinese circuit breaker going wacky

ECM and PCM both talk to the cluster. Fuel Guage and volt gauge is from the PCM. The oil pressure, coolant temp, tach are cover by the ECM. As for speedometer the ABS talks to the cluster.

@dripley, this may be a place to start. This is the operational description of the voltage gauge from my 2002 repair manual. This may at least explain why your problem corrected itself for now.
Just got in from and about 8 miles out I noticed the the check gauges light is on and the volt gauge is on 0. Roll in the driveway and put the meter and its putting out 13,8 volts on the charge stud.
