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 (2) using the thermal transfer pad (1) and mounting nut (3) and tighten to 25 in-lb (2.8
N·m) (Figure 12-18, Page 12-13). See following NOTE.
NOTE: See the different locations for the diode (Figure 12-17, Page 12-12 or Figure 12-18, Page 12-13).
4. Route and connect the red and white diode wires to the solenoid posts in the electrical component box.
See following WARNING.

WARNING
• Incorrect wiring could result in severe injury or death.
• Diode and solenoid connections must have correct polarity.
• Keep all persons clear of engine belts when making final connections.
4.1. Connect the 12-gauge red wire from the diode to the solenoid post with the fuse block and battery
red wires and tighten lock nut to 90 in-lb (10.2 N·m) (Figure 12-18, Page 12-13).
4.2. Connect the 12-gauge white wire to the other large solenoid post, along with the red wire from the
voltage regulator and white wire from the starter/generator and tighten nut to 90 in-lb (10.2 N·m).
5. Replace the electrical component box cover (6) and screw (5) and tighten the screw to 18 in-lb (2.0 N·m).
