ELECTRICAL WIRING CIRCUITS

NOTE: Beginning with engine serial No. 3987113, the

standard wiring circuits for all 12 voltelectrical equipment is

negative ground polarity, in place of the previously

furnished positive ground. All 6 volt systems remain

positive ground.

The Flywheel Alternator circuit illustrated in Fig. 12

always was and is a negative ground system. It replaces

the previously furnished gear driven generator which

was available both negative and positive ground.

Wiring diagram and service parts information for obso-

lete gear driven type generator can be obtained by
