Main Fuse / Fuse Holder Location
A 15 Amp fuse protects the main electrical system. The
fuse is located in the battery compartment.
NOTE: Use only the recommended fuse capacity, as
use of a higher amperage fuse to correct blown-fuse
situations could lead to electrical component
damage.
Voltage Regulator / Rectifier
The voltage regulator / rectifier is located near the front of
the engine.
The regulator diodes can be tested with an ohm meter.
Attach the positive ‘+’ lead to the BK pin and the negative
‘-’ lead to the WHT pin. There should be measurable
resistance. Reverse the leads and test. There should be
no continuity. The YEL and RED pins should be tested the
same and achieve the same results.
Stator / Alternator Tests
Two tests can be performed using a multimeter to
determine the condition of the stator:
TEST 1: Measure resistance value of each stator leg.
1. Measure the resistance value of the stator legs. Use
the following chart as a reference when testing.
TEST 2: Measure AC voltage output of each stator leg.
Test at cranking rpm with a voltmeter set to read AC volts.
1. Turn over the engine with the starter motor.
2. First measure from the red wire (RD) to engine
ground. Compare readings to specifications.
3. Next measure from the yellow wire (YE) to engine
ground. Compare readings to specifications.
NOTE: To check the charging system output further,
start the engine and perform the same tests. Voltage
should increase with increased RPM.
