A technician measures 14.1 volts at the battery with the engine running at 2,000 RPM. The headlights and other accessories are on. Is this reading normal?
-

No, the alternator is undercharging โ voltage should be above 15 volts with load
-
B
Yes, 13.5-14.5 volts is the normal charging voltage range
-
C
No, voltage should drop below 12.6 volts when accessories are on
-
D
Yes, but only if the battery is fully charged; otherwise it indicates a weak alternator
