Hour Meter/Control Module
Purpose
How It Works
The hour meter/control module keeps track of the actual
running hours of the engine. It has safety interlock
indicators to let the operator know the position of the
corresponding component. It also provides the operator
with the battery output voltage.
1. Hour Meter – Hours are accumulated when 12.8
volts are generated by the engine. Battery voltage is
not great enough to engage the hour meter function
(Fig. 1448).
2. Battery Light Indicator – If the ignition key is turned
to the “ON” position for a few seconds, the battery
voltage will be displayed in the area the hours are
normally displayed. The battery light turns on when
the battery charge is below 12 volts (Fig. 1448).
3. Safety Interlock Indicators – The display uses black
triangles to indicate the position of an interlock
system component (Fig. 1448).
Note: The neutral indicator is the only triangle that
MUST be on for the unit to start.
Location
The hour meter is located on the control panel (Fig.
1447).

Testing
The hour meter is tested by testing the inputs. As an
example, if the neutral indicator (black triangle) will
not illuminate, the neutral switch needs to be tested. If
the switch tests good, the hour meter is at fault. This
troubleshooting method will work for any of the inputs.
