Alternator
Excitation
The residual magnetism of an alternator is very low therefore some field current must be supplied
to the rotor to initiate the generation of power by the machine.

Observe vehicle
battery polarity prior to connecting output cables to the alternator. Reverse battery
polarity will destroy the alternator rectifier diodes.
ALTERNATOR REAR HOUSING
ROTATION
For special installation requirements, the alternator rear housing may be rotated to one of four
different positions that are spaced 90° apart.
To
rotate the rear housing, proceed as follows:
1.
Detach plastic cover from rear housing.
2.
Remove the four (4) through-bolts using a 1/4" nutdriver
or
socket. See illustration below.
3.
Rotate the housing (clockwise or counter-clockwise) to the desired location. The stator assembly
must be rotated with the rear housing.
4.
Replace through-bolts. Tighten through-bolts alternately and evenly until tight. Check that rotor
shaft turns
freely after re-assembly.
5.
Reattach plastic cover to rear housing. NOTE: Be sure felt gasket located on inside of cover is
in
place.
