8. Connect the battery cables, positive (+) cable first.
9. Leave the Forward/Reverse handle in the NEUTRAL position.
10. Monitor the multimeter while turning the key switch to the ON position. The multimeter should indicate
0 (zero) VDC with the key in the OFF position and approximately 12 VDC with the key switch in the ON
position.
11. If the voltage reading is approximately 12 VDC with the key switch in the OFF position, check the fan
relay for proper wiring and function. See Test Procedure 10 – Fan Relay on page 11c-23.
12. If the voltage reading is not approximately 12 VDC with the key switch in the ON position, check the fol-
lowing:
• Diode 2 for failure in closed condition. See Test Procedure 13B – Diode 2 on wire 40 on
page 11c-31.
• Fan relay for proper wiring and function. See Test Procedure 10 – Fan Relay on page 11c-23.
• Both 30-amp fuses (on wires w109 and w125). See Test Procedure 2 – Fuse on page 11c-16.
• Key switch. See Test Procedure 5 – Key Switch (ON Position) on page 11c-19.
• Connections and wire continuity for wires w112, w44, w52, w51, w107, w109, w114, w146, w125, w24,
and w48.
TEST PROCEDURE 13 – WIRE HARNESS DIODES
See General Warning, Section 1, Page 1-1.
A diode is designed to conduct current in one direction only. Depending on the application, diodes are used
in the vehicle to control electrical system logic, or to help protect relay and switch contacts from excessive arc-
ing. See following NOTE.
NOTE: If a diode conducts current in both directions, the diode has failed closed. If a diode will not conduct
current in either direction, the diode has failed open (Figure 11c-25, Page 11c-29).
