Main Fuse / Fuse Holder Location; Voltage Regulator / Rectifier; Stator / Alternator Tests - Polaris PREDATOR 50 2009 Manual

Main Fuse / Fuse Holder Location

A 7 Amp fuse protects the main electrical system on all youth
models. See illustrations for fuse locations.

7 Amp Fuse
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 under the LH rear
fender on the 90cc models and under the RH front fender on the
50cc models.
The regulator diodes can be tested with an ohm meter. Attach the
postive '+' lead to position #1 and the negative '-' lead to
position #2. There should be measurable resistance. Reverse the
leads and test. There should be no continuity. Positions #3 and
#4 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 (alternator).
Take Measurements on
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.

BK to Ground
Battery Charge Coil BK to RD
BK to YE
TEST 2: Measure AC voltage output of each stator leg. Test at
cranking rpm with a voltmeter set to read AC volts.
2. Turn over the engine with the starter motor.
3. First measure from the red wire (RD) to engine ground.
Compare readings to specifications.
4. 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.
