Voltmeter Fluctuation
This information applies to 2005-07 Cadillac Escalade, Chevrolet Avalanche, Silverado, Silverado Classic, Suburban, Tahoe, GMC Sierra, Sierra Classic, Yukon with Regulated Voltage Control (RVC).
Some customers may comment that the voltmeter fluctuates between 12 and 14 volts.
The RVC system controls voltage based on such parameters as battery state of charge, battery electrolyte temperature, battery current, and electrical loads. This causes the voltmeter to fluctuate between 12 and 14 volts.
This fluctuation with the RVC system is normal system operation and no repairs should be attempted.
