TEST PROCEDURE 24 – BATTERY TEST (UNDER LOAD)
Read DANGER and WARNING on page 11-1.
NOTE: Keep the battery connected while performing this test procedure.
1. Place the Forward/Reverse handle in the NEUTRAL position, and chock the wheels.
2. Set a multimeter to 20 volts 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 START position and hold it in the START position while noting the voltage
reading 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) (see following
NOTE), check the starter/generator.
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 11-21.
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 11-27.
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/Genera-
tor (Starter Function) on page 11-29.
TEST PROCEDURE 25 – FUEL LEVEL SENDING UNIT
Read DANGER and WARNING on page 11-1.
∆ 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. Turn the key switch to the OFF position, put the Forward/Reverse handle in the NEUTRAL position, dis-
connect the battery cables, negative cable (–) first, and chock the wheels.
2. Disconnect the orange wire from the center post of the fuel level sending unit.
3. With a multimeter set to 2k
Ω
(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 11-44,
Page 11-40).
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.
