Battery Condition Indicator

With the ignition switch in the "ON" position, the pointer should be at mid (13 volts) position. With both the ignition and the headlights switched on, the pointer should be between the bottom Red segment and 13 volts. If the pointer is in the bottom Red segment, it indicates the battery and/or charging system needs servicing. When engine is running above idling speed, the pointer should be between 13 volts and the top Red segment. If the pointer remains in the red segment for longer than 10 minutes then the charging rate is too high and the system needs to be checked and serviced as necessary.
