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.
3.2. If the reading is below 9.6 volts, with an electrolyte temperature of 70 °F (21 °C), check the battery.
See Test Procedure 1 – Battery on page 12-9.
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 12-15.
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 12-16.
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 the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-2.
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 send-
ing unit. Place the black (–) probe on the ground connection of the sending unit
(Figure 12-31,
Page 12-32)
.
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.
