NOTE: Due to manufacturing differences, meter internal polarity may vary from manufacturer to manufacturer. As a result, the
test readings may be a direct reversal of the readings specified. If so, reverse the meter leads and perform the test again.
A slight variance from the listed specification does not necessarily indicate a defective component.

Voltage Regulator/Rectifier Removal and Installation
Removal
1.
Release the reusable cable tie that secures the voltage regulator/rectifier wires.
2. Disconnect the bullet connectors for the white, yellow, and red wires from the voltage regulator/rectifier.
3. Remove the two screws that secure the voltage regulator to the bracket, and remove the voltage regulator.
a - Bullet connectors
b - Reusable cable tie
c - Voltage regulator mounting screws (2)
d - Voltage regulator ground (black) wire
Installation
1.
Attach the voltage regulator to its mounting bracket with two screws. Be certain to attach the ring terminal for the ground
(black) wire with one of the screws.
2. Tighten the screws to the specified torque.
Description Nm lb‑in. lb‑ft
