TROUBLESHOOTING AND ELECTRICAL SYSTEM:
PEDAL-START GAS VEHICLE
TEST PROCEDURE 17 – Reverse Buzzer and Reverse Buzzer Limit Switch
See General Warnings on page 1-1.
NOTE: Reverse Buzzer: This is a voltage test.
Reverse Buzzer Limit Switch: This is a continuity test.
A reverse buzzer is mounted on the back side of the instrument panel. On some models, another reverse buzzer is
also mounted on a bracket at the left rear of the vehicle. The reverse buzzer is powered by the 10-amp ATM fuse
located on the main wire harness in front of the engine.
The reverse buzzer limit switch is located on the Forward/Reverse shifter. Purple/white and orange wires are
connected to it.
1.
If necessary, see Testing Basics on page 18-14.
2.
To test the front reverse buzzer, remove instrument panel. See Instrument Panel Removal on page 4-10.
3.
Check for proper wiring and tight connections.
4.
Check that battery voltage is present in the orange/white wire at buzzer.
5.
Place the Forward/Reverse handle in the REVERSE position. The buzzer should sound. If not, check limit
switch in the next steps.
6.
Disconnect black/orange wire from buzzer.
7.
With Forward/Reverse handle still in the REVERSE position, there should be continuity between the black/orange
wire and ground. With Forward/Reverse handle still in the FORWARD position, there should be no continuity. If
either reading is incorrect, replace limit switch. See Reverse Buzzer Limit Switch Removal on page 20-21.
8.
If limit switch is operating properly, replace buzzer. See Reverse Warning Buzzer Removal, Section 20,
Page 20-19.
TEST PROCEDURE 18 – Low Oil Warning Light (LED)
See General Warnings on page 1-1.
NOTE: This is a voltage test.
When the key switch is placed in the ON position, the Low Oil Warning Light will illuminate for approximately 3
seconds as a bulb check function.
1.
If low oil warning light does not illuminate for approximately 3 seconds when the key switch is placed in the ON
position, proceed with the steps below.
2.
If necessary, see Testing Basics on page 18-14.
3.
Remove the instrument panel. See Instrument Panel Removal on page 4-10.
4.
Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary. See
Wiring Diagrams on page 18-8.
5.
With key switch in ON position, test for battery voltage at yellow wire to low oil warning light. If no voltage, check
key switch. See Key Switch (Start Circuit) on page 18-24.
6.
If battery voltage is present, use a test lead to ground the black wire terminal of low oil warning light. Light
should illuminate. If not, replace low oil warning light.
