NEUTRAL REV GAS VEHICLE

DIODE

See General Warning on page 1-1.
TESTING THE DIODE
See Test Procedure 10 – Diode (Generator Circuit) on page 11-18.

DIODE REMOVAL

1. Turn the key switch OFF and remove the key. Place the Forward/Reverse handle in the NEUTRAL position.
Chock the wheels.
2. Disconnect battery and spark plug wire(s). See Disconnecting the Battery – Gasoline Vehicles, Section
1, Page 1-3.
3. Remove the carburetor air intake hose to allow easy access to the electrical component box cover.
4. Remove the cover screw (1) and electrical component box cover (2) (Figure 13-16, Page 13-16).
5. Remove the nuts (3) from the two large solenoid posts and disconnect the diode wires from the solenoid (4).
5.1. Observe color orientation of the wires with the terminal locations on the solenoid. The 12-gauge red wire (5)
from the diode should be attached to the same terminal as the red wire (6) from the fuse block, and the red
wire (7) from the battery. The 12-gauge white wire (8) should be attached to the other large solenoid post,
along with the red wire (9) from the voltage regulator and the white wire (10) from the starter/generator.
6. Remove the nut (11) and remove the diode (12) and thermal transfer pad (13) from the vehicle frame I-beam
(14) (Figure 13-16, Page 13-16).

DIODE INSTALLATION

1. Thoroughly clean and dry the area of the I-beam (14) where the new diode (12) is to be attached.
2. Peel the protective film from both sides of the new thermal pad (13) (Figure 13-16, Page 13-16). See following
CAUTION.
CAUTION
• Be sure to remove and discard the protective film from both sides of the thermal pad before installing
it. If not removed, the film will reduce the thermal heat transfer and therefore reduce the power
handling capability of the diode, causing it to overheat and damage the electrical system.
3. Mount the diode (12) using the thermal transfer pad (13) and mounting nut (11) and tighten to 25 in-lb (2.8 N·m)
(Figure 13-16, Page 13-16). See following NOTE.
NOTE: Diodes are mounted in one of two different locations, depending on the vehicle model (Figure 13-16, Page
13-16).
