This gauge indicates the voltage across the battery.
Verify that 12 volts DC is present across the two
terminals when the ignition key is in the RUN position. If
so, and the meter is not running, replace the meter. If 12
volts is not present, check the connections. The meter is
a permanently sealed unit and is not repairable.
Testing How It Works
The meter movement is proportional to the voltage
level across the two terminals of the battery. This is
accomplished by placing a resistor in parallel with the
meter movement.
1. Remove the control panel from the tank by removing
4 screws.
2. With a Volt-ohm meter, place the negative probe on
the battery negative terminal. Turn the ignition key
to the RUN position.
3. Place the positive probe of the meter to the I (orange
wire) terminal. You should read 12 volts DC on the
meter.
4. Move the positive probe of the meter to the G (black
wire) terminal. You should get 0 volts DC on the
meter.
5. If you DO NOT get the above readings, replace the
voltmeter.
