Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
Most likely causes
Alternator regulator failure
mediumA plausible cause — test and verify before replacing parts.
Wiring shorted to a higher-voltage circuit
lowLess common, but worth ruling out after the more likely causes.
Connector pins corroded - high contact resistance
