LeSabre V6-181 3.0L (1986)
Volt Meter Gauge: Testing and Inspection
The voltmeter is a gauge which measures the electrical flow from the battery to indicate whether the battery output is within tolerances. The voltmeter
reading can range from 13.5---14.0 volts under normal operating conditions. If an undercharge or overcharge condition is indicated for an extended
period, the battery and charging system should be checked.
To check voltmeter, turn key and headlights on with engine off. Pointer should move to 12.5 volts. If no needle movement is observed, check
connections from battery to circuit breaker. If connections are tight and meter shows no movement, check wire continuity. If wire continuity is
satisfactory, the meter is inoperative and must be replaced.
