Hour Meter
The hour meter used on the machine records the
amount of time that the ignition switch is in the ON posi-
tion.
Testing
1. Remove knob from lift lever.
2. Remove four (4) screws and flat washers that secure
control panel to console (Fig. 10). Lift control panel, un-
plug wire harness connector from hour meter and re-
move control panel from machine.
3. Connect the positive (+) terminal of a 12 VDC source
to the positive (+) terminal of the hour meter.
4. Connect the negative (–) terminal of the voltage
source to the other terminal of the hour meter.
5. The hour meter should move 1/10 of an hour in six
minutes.
6. Disconnect the voltage source from the hour meter.
7. Connect wire harness connector to hour meter and
position control panel to console. Secure control panel
