TEST PROCEDURE 33 – Hour Meter
See General Warnings, Section 1, Page 1-2.
NOTE:
Keep the battery connected during this test procedure.
1.
Place the Forward/Reverse handle in NEUTRAL. Chock the wheels.
2.
With the key switch OFF, check the hour meter display. It is powered by an internal battery and should always be
on, even with the engine off and the key removed.
3.
Start the engine and let it idle.
See following DANGER.
DANGER
• Do not operate vehicle in an enclosed area without proper ventilation. The engine produces carbon
monoxide, which is an odorless, deadly poison.
4.
With engine idling, the "hour glass" icon should flash. If not, check the low oil warning light and the oil pressure
switch.
See following NOTE. See also Test Procedure 29 – Low Oil Warning Light Circuit on page 12-38.
NOTE:
The hour meter is designed to record actual engine running time and will not start adding increments until the
engine is running and the oil pressure switch has opened.
5.
If the hour meter still does not function after the low oil warning light, oil pressure switch, and all of the appropriate
wires have been checked for continuity, replace the fuel gauge/hour meter.
TEST PROCEDURE 34 – Light Switch
See General Warnings, Section 1, Page 1-2.
NOTE:
The headlight circuit is protected by the 20-amp fuse. Check the fuse before this procedure is performed.
See
Test Procedure 2 – Fuse on page 12-13.
Keep the battery connected during this test procedure.
1.
Disable the vehicle.
See Disabling the Vehicle on page 1-3.
