TEST PROCEDURE 22 – OIL WARNING LIGHT
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 posi-
tion. Chock the wheels.
2. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-2.
3. Remove the instrument panel.
See Key Switch Removal, Section 13, Page 13-14.
4. Ensure that the wires are connected correctly and are tight. If they are not, rewire or tighten as necessary.
5. Disconnect the yellow wire (to the oil level sensor) from the terminal on the oil light. Using an alligator clip
jumper wire, connect the oil 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.
6. Turn the key switch to the ON position. The oil light should illuminate. If it does not, check continuity of
the yellow wire that connects the key switch to the oil light through a sonic weld connection within the wire
harness. If there is no continuity in the wire, replace the wire. Then test the key switch.
See Test Pro-
cedure 4 – Key Switch (Starter Circuit) on page 11-13.
If the yellow wire and the key switch test okay,
then replace the oil light.
TEST PROCEDURE 23 – LOCKOUT CAM
See General Warning on page 1-1.
Check to be sure the lobes on the cam are pressing the lockout cam limit switch when the Forward/Reverse
shifter is in the NEUTRAL position only. The limit switch should make an audible click as it is pressed. If it does
not, check for wear on the cam lobe. If the cam lobe will not activate the limit switch, replace the cam.
TEST PROCEDURE 24 – BATTERY TEST (UNDER LOAD)
See General Warning on page 1-1.
NOTE:
Keep the battery connected while performing this test procedure.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL posi-
tion. Chock the wheels.
2. Set a multimeter to 20 volts and place the red (+) probe on the F2 (white wire) terminal on the starter/gen-
erator. Place the black (–) probe on the negative battery post.
3. Turn the key switch to the START position and hold it in the START position while noting the voltage read-
ing on the multimeter (with the key in the START position the battery is under load).
3.1. If the voltage reading is over 9.6 volts at 70 °F (21 °C) (electrolyte temperature) check the starter/
generator.
See following NOTE.
NOTE:
The voltage reading is taken at 70 °F (21 °C). At lower electrolyte temperatures the voltage reading
will be lower.
3.2. If the reading is below 9.6 volts at 70 °F (21 °C) (electrolyte temperature), check the battery.
See
Test Procedure 1 – Battery on page 11-9.
3.3. If the reading is zero, there may be NO continuity across the large posts of the solenoid.
See Test
Procedure 6 – Solenoid on page 11-15.
4. If all of the test results are good and the voltage reading is zero, there may be a broken or damaged 6-
gauge white wire from the solenoid to the starter/generator.
See Test Procedure 8 – Starter/Generator
(Starter Function) on page 11-17.
