TEST PROCEDURE 19 – Oil Level Sensor
See General Warnings on page 1-1.
NOTE:
Keep the battery connected while performing this test procedure.
This procedure requires the oil to be drained from the engine.
1.
If necessary, see Testing Basics on page 18-15.
2.
Place the Forward/Reverse handle in the NEUTRAL position, the neutral lockout switch in the MAINTENANCE
position, turn the key switch to the OFF position, disconnect the spark plug wire, and chock the wheels.
3.
Ensure that the low oil warning light and all connecting wires are functioning correctly.
4.
Drain the engine oil into an approved container and properly dispose of used oil.
5.
Turn the key switch ON, closing the circuit. The low oil warning light should illuminate. If the low oil warning light
does not illuminate, the oil level sensor needs to be replaced.
See Oil Level Sensor Removal on page 22-12.
6.
Fill the engine with new oil before returning the vehicle to service.
See Engine Oil – Gasoline Vehicle on
TEST PROCEDURE 20 – Battery Test (Under Load)
See General Warnings on page 1-1.
NOTE:
Keep the battery connected while performing this test procedure.
1.
If necessary, see Testing Basics on page 18-15.
2.
Place the Forward/Reverse handle in the NEUTRAL position and the neutral lockout switch in the MAINTENANCE
position. Chock the wheels.
3.
Set a multimeter to 20 volts DC and place the red (+) probe on the F2 (white wire) terminal on the starter/generator.
Place the black (–) probe on the negative (–) battery post.
4.
Turn the key switch to the ON position, leave the Forward/Reverse shifter in the NEUTRAL position and press the
accelerator pedal (with the accelerator pedal pressed, the battery is under load).
4.1.
If the voltage reading is over 9.6 volts, with an electrolyte temperature of 70 °F (21 °C), check the
starter/generator.
See following NOTE.
NOTE:
The voltage reading listed is for electrolyte at 70 °F (21 °C). At lower electrolyte temperatures the voltage
reading will be lower.
5.
If the reading is below 9.6 volts, with an electrolyte temperature of 70 °F (21 °C), check the battery.
5.1.
If the reading is zero, there may be no continuity across the large posts of the solenoid.
6.
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 Starter/Generator (Starter Function) on page 18-30.
