GASOLINE VEHICLE - TROUBLESHOOTING
AND ELECTRICAL SYSTEM
6.
Put the red (+) probe of the multimeter on the positive post of the battery.
7.
Put the black (–) probe on the negative post of the battery. Record the voltage reading.
8.
Put the red (+) probe on terminal 2 of the fuel gauge/hour meter with the blue wire (2) connected.
9.
Put the black (–) probe on terminal 1 of the fuel gauge/hour meter with the black wire (3) connected.
10.
Turn the key switch ON. The voltage reading should be the same as the battery voltage reading recorded earlier.
10.1.
If not, check the continuity of the blue and black wires.
11.
Make sure that the orange wire (1) is disconnected

Fuel Gauge Voltage Test - Terminal 4
12.
Put the black (-) probe on terminal 1 of the fuel gauge/hour meter.
13.
Put the red (+) probe on terminal 4 of the fuel gauge/hour meter. The voltage reading should be approximately
4.94 volts.
13.1.
If the reading is incorrect, replace the fuel gauge/hour meter.
TEST PROCEDURE 21 – Hour Meter
DANGER
• Do not operate vehicle in an enclosed area without proper ventilation. The engine produces carbon
monoxide, which is an odorless, deadly poison.
NOTE:
Keep the battery connected while performing this test procedure.
1.
Disable the vehicle.
2.
Make sure that the key switch OFF.
3.
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.
4.
Start the engine and let it idle.
5.
With engine idling, the "hour glass" icon should flash.
5.1.
If not, check the voltage regulator.
See following NOTE.
NOTE:
The hour meter is designed to record actual engine running time and will not start adding increments until
the engine is running.
6.
If the hour meter still does not function after the voltage regulator and all of the appropriate wires have been
checked for continuity, replace the fuel gauge/hour meter.
