Reassembly
Follow the disassembly steps in reverse order to
reassemble the generator. Pay close attention to the
items below.
• Be very careful not to reverse battery polarity.
Reversed battery polarity will destroy the rectifie
r
diodes.
• Do not ground the generator B-terminal. Heat and
fire damage to the harness will result.
• If using a fast charge procedure, be sure to
disconnect the battery positive cable. If you do not,
the rectifier diodes will be exposed to high positive
voltage that will destroy them.
• Be very careful to reassemble the parts to thei
r
original positions. Particular care must be taken
with insulated parts.
• Carefully clean all insulated parts so that they are
completely free of oil and/or grease.
• Be sure that B-terminal twist-type stoppers (round
terminal) are securely inserted before tightening
the nuts.
Final Assembly
1. Use a bench press to install the rotor and rear
cover to the front cover.
