Test Procedure 13B – Diode 2 on wire 40
See General Warning, Section 1, Page 1-1.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in NEUTRAL. Chock
the wheels.
2. Disconnect the battery cables as instructed. See WARNING “To avoid unintentionally starting...” in
General Warning, Section 1, Page 1-1.
3. Raise the hood.
4. Disconnect the two-pin connector between the fan and the wire harness (Figure 11c-23, Page 11c-28) .
5. Set the multimeter to the diode test function (
ç
).
6. Connect the black (–) probe of the multimeter to the frame (ground).
7. Connect the red (+) probe of the multimeter to the 14-gauge blue wire (w52) on the two-pin connector
(wire harness side).
8. The reading should indicate an over limit (no continuity). If the diode conducts current (shows continuity)
with the meter probes connected as described, the diode has failed and must be replaced. See Wire
Harness Diode Removal, Section 12c, Page 12c-20.
9. Reverse the multimeter probes and note the reading. The multimeter should indicate approximately 540
mV, however, a range of 400-700 mV is acceptable.
10. If the readings obtained in the previous steps are incorrect, replace the diode. See Wire Harness Diode
Removal, Section 12c, Page 12c-20.
Test Procedure 13C – Diode 3 on wire 144
Diode 3 is only used on early 2007 vehicles equipped with the two piece wire harness and a differential relay.
See General Warning, Section 1, Page 1-1.
1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in NEUTRAL. Chock
the wheels.
2. Disconnect the battery cables as instructed. See WARNING “To avoid unintentionally starting...” in
General Warning, Section 1, Page 1-1.
3. Remove the start relay, differential relay, fan relay, and accessory relay from the multi-pin connector
located on the electrical component mounting plate.
4. Disconnect the two-pin connector between the neutral switch and the wire harness (Figure 11c-26,
Page 11c-32) .
5. Set the multimeter to the diode test function (
ç
).
6. Connect the black (–) probe of the multimeter to the 18-gauge black/white wire (w142) at the neutral
switch two-pin connector.
7. Connect the red (+) probe of the multimeter to the 18-gauge black wire (w139) on the multi-pin differential
relay connector located on the electrical component mounting plate.
