Test Procedures
TROUBLESHOOTING AND ELECTRICAL SYSTEM:
PEDAL-START GAS VEHICLE
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. Place the Forward/Reverse handle in the NEUTRAL position and the neutral lockout switch in the MAINTENANCE
position. Chock the wheels.
2. 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.
3. 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).
3.1. 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.
4. If the reading is below 9.6 volts, with an electrolyte temperature of 70 °F (21 °C), check the battery. See
Battery on page 12-10.
4.1. If the reading is zero, there may be no continuity across the large posts of the solenoid. See Solenoid
on page 12-16.
5. 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 12-18.
TEST PROCEDURE 25 – Fuel Level Sending Unit
See General Warning on page 1-1.
WARNING
• To avoid the possibility of fire or explosion, make sure the fuel tank cap is securely in place while
performing this test procedure.
1. Disconnect battery. See Disconnecting the Battery – Gasoline Vehicles, Section 1, Page 1-3.
2. Disconnect the orange wire from the center post of the fuel level sending unit.
3. With a multimeter set to 2k ohms, place the red (+) probe of the multimeter on the center post of the sending unit.
Place the black (–) probe on the ground connection of the sending unit
(Figure 12-32, Page 12-35) .
4. The following resistance readings (in ohms) should be obtained depending on the position of the float inside
the fuel tank. The resistance reading will vary according to the exact position of the float. The chart below may
be used as a guideline to determine if the fuel level sending unit is operating correctly. Make sure the float
is at the surface of the fuel in the tank.
FLOAT POSITION RESISTANCE READING FUEL GAUGE READINGS
Lower position (tank empty) 240 ± 20 ohms Empty
Center position (tank half full) 120 ± 20 ohms Half full
Upper position (tank full) 60 ± 20 ohms Full
