Flywheel Magnet Identification; Equipment Used To Test Alternators - Vanguard OHV V-Twin User Manual

Flywheel Magnet Identification

NOTE: Does NOT include engines with the Power-
Linkt system.
The V-Twin flywheels have a ring of magnets (1) on
the inside of the flywheel, Fig. 7, that provides the
magnetic field for the charging systems. The size of
the magnet determines the alternator output.
NOTE: Flywheels are NOT interchangeable. Use
ONLY correct flywheel for the application.

Equipment Used to Test Alternators

Digital Multimeter
The Digital Multimeter #19464, Fig. 8, is available
from your Briggs & Stratton source of supply. The
Digital Multimeter can be used to read volts, ohms,
amperes, and to test diodes.
Fig. 8
DC Shunt
The Digital Multimeter will withstand DC input of 10
- 20 amps for up to 30 seconds. When checking DC
output on 16 and 20 amp regulated systems, use the
DC Shunt #19359, Fig. 9, to avoid blowing a fuse in
the Multimeter.
NOTE: The Digital Multimeter is equipped with two
fuses to prevent damage to the meter if the
input limits of the meter are exceeded.
Check the fuses if the meter displays a read-
ing of 0.00 when testing DC output (V
Refer to the FLUKE Operators Manual for
this procedure. Replacement fuses, Part #
19449, are available from your Briggs &
Stratton source of supply.
