Test Procedures
TROUBLESHOOTING AND ELECTRICAL SYSTEM:
KEY-START WITH NEUTRAL REV GAS VEHICLE
Load Test
1.
Connect a 160-ampere load tester to the battery posts.
2.
Turn the switch on the load tester to the ON position.
3.
Read the battery voltage after the load tester has been turned ON for 15 seconds. Compare the battery’s voltage
reading with the table below. Make sure you have the correct ambient temperature.
4.
If the battery is found to be good, or if the electrical problem continues after the battery has been replaced
with a good one, test the electrical circuits.

TEST PROCEDURE 2 – Fuse
See General Warning on page 1-1.
The fuse (red 10 amp) is located in the electrical component box.
1.
Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL position.
Chock the wheels.
2.
Disconnect battery.
See Disconnecting the Battery – Gasoline Vehicles, Section 1, Page 1-3.
3.
Remove the cover on the electrical component box.
4.
Check that wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
5.
Remove fuse to be tested from the fuse block.
See Fuse Removal, Section 13, Page 13-20.
The red 10 amp
fuse protects the solenoid for the starter (cranking) circuit. The 20 amp fuse at the yellow wire connection
protects the headlights.
6.
Connect the probes of a multimeter set to 200 ohms to the fuse terminals. The reading should be continuity. If
there is no continuity, determine and repair the cause of the fuse failure. Replace the fuse with a properly
rated new one.
7.
Connect battery and spark plug wire(s).
See Connecting the Battery – Gasoline Vehicles, Section 1, Page 1-3.
TEST PROCEDURE 3 – Ground Cables
See General Warning on page 1-1.
1.
Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL position.
Chock the wheels.
2.
Disconnect battery and spark plug wire(s).
See Disconnecting the Battery – Gasoline Vehicles, Section
3.
Check the starter/generator ground strap.
3.1. Set the multimeter to 200 ohms. Place the red (+) probe on the (A2) terminal of the starter/generator and
place the black (–) probe on the vehicle frame
. The reading should be continuity.
