TEST PROCEDURE 19 – REVERSE BUZZER LIMIT SWITCH
See General Warning, Section 10, Page 10-1.
NOTE:
Keep the battery connected while performing this test procedure.
The reverse buzzer limit switch is located on the Forward/Reverse shifter; red/white and orange wires are
connected to it.
1. Place the neutral lockout cam in the SERVICE (MAINTENANCE) position, put the Forward/Reverse han-
dle in the NEUTRAL position, and chock the wheels.
2. Move the Forward/Reverse handle to REVERSE and listen for an audible click from the limit switch. If
there is no click, check the switch for proper alignment and switch arm movement.
3. If the switch is being activated but the buzzer does not function, place the red (+) probe of the multimeter
on one terminal and the black (–) probe on the other terminal of the limit switch. Without the lever
pressed, the reading should be no continuity. Press the lever and the reading should be continuity. If
either reading is incorrect, replace the limit switch.
See Reverse Buzzer Limit Switch Removal,
Section 12, Page 12-20.
TEST PROCEDURE 20 – REVERSE BUZZER
See General Warning, Section 10, Page 10-1.
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning, Section 10, Page 10-1.
2. Remove the center dash assembly.
See Key Switch Removal, Section 12, Page 12-13.
3. Check for proper wiring and tight connections. Using a multimeter, individually check for continuity
through each wire that connects to the reverse buzzer. If the buzzer will not function when properly wired,
replace the buzzer.
See Reverse Warning Buzzer Removal, Section 12, Page 12-19.
TEST PROCEDURE 21 – LOW OIL WARNING LIGHT
See General Warning, Section 10, Page 10-1.
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning, Section 10, Page 10-1.
2. Remove the center dash assembly.
See Key Switch Removal, Section 12, Page 12-13.
3. Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
4. Disconnect the yellow wire (to the oil level sensor) from the terminal on the low oil warning light. Using
an alligator clip jumper wire, connect the low oil warning light terminal to the vehicle frame. Connect the
red (+) battery cable to the positive (+) battery post, then attach the black (–) cable to the negative (–)
battery post.
5. Turn the key switch ON. The low oil warning light should illuminate. If it does not, check continuity of the
yellow wire that connects the key switch to the low oil warning light. If there is no continuity in the wire,
replace the wire. Then test the key switch.
See Test Procedure 4 – Key Switch (Starter Circuit) on
page 11-12
. If the yellow wire and the key switch test okay, then replace the low oil warning light.
