Prestolite Alternator - Model 50
105 Amp Charging System
Diagnostic Procedures
NOTE: Units manufactured with
CYCLE-SENTRY and alternators with integral
regulators MUST use replacement alternators
with integral regulators.
NOTE: The F7 fuse must be installed in the
relay board on units equipped with the Prestolite
alternator. If the F7 fuse is not in place, the
alternator will not charge properly.
Complete the following checkout procedure
before replacing the voltage regulator or the
alternator.
•
When testing alternators use accurate
equipment such as a Thermo King
P/N 204-615 (FLUKE 23) digital multimeter
and a Thermo King P/N 204-613 amp clamp
or an equivalent.
CAUTION: Full-fielding alternators with
the integral regulator is accomplished by
installing a jumper from terminal F2 to
ground. Attempting to full-field the
alternator by applying battery voltage to
terminal F2 will cause voltage regulator
failure.
