Hour Meter
The hour meter is located on the control panel as shown
(Fig. 400).
Fig 400 PICT-0199
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.

Since a normal clock might be affected by variations in
voltage and current, the hour meter is made up of an
electric “winder” and a mechanical clock movement.
When power is applied, a coil is energized to wind the
movement. The movement unwinds in about 2 seconds.
