DIODE

See General Warning, Section 1, Page 1-1.
Testing the Diode
See Test Procedure 10, Section 11, Page 11-29.
Diode Removal
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 (Figure 12-1, Page 12-1). See WARNING "To avoid unin-
tentionally starting..." in General Warning, Section 1, Page 1-1.
3. Remove the carburetor air intake hose to allow easy access to the electrical component box cover.
4. Remove the cover screw (5) and electrical component box cover (6) (Figure 12-18, Page 12-13).
5. Remove the nuts (7) from the two large solenoid posts and disconnect the diode wires from the solenoid.
5.1. Observe color orientation of the wires with the terminal locations on the solenoid. The 12-gauge red
wire from the diode should be attached to the same terminal as the red wire from the fuse block,
and the red wire from the battery. The 12-gauge white wire should be attached to the other large
solenoid post, along with the red wire from the voltage regulator and the white wire from the starter/
generator.
6. Remove the nut (3) and remove the diode (2) and thermal transfer pad (1) from the vehicle frame
(Figure 12-17, Page 12-12).
Diode Installation
1. Thoroughly clean and dry the area where the new diode is to be attached.
2. Peel the protective film from both sides of the new thermal pad (1) (Figure 12-18, Page 12-13). See fol-
lowing CAUTION.
