Short Circuit Current (Ac Amp Test); Regulated Voltage - Polaris 2003 Pro X Service Manual

ELECTRICAL
Unregulated Voltage - continued
7. Turn the multitester dial to the Volts AC (Vµ) position.
8. Disconnect the alternator to main harness connector at
engine.
9. Connect one of the tester leads to the yellow alternator
wire and the other lead to the brown alternator wire.
NOTE: On floating alternators, the yellow/red stator
wire should connect to the brown stator wire. If it does
not, the system will not have a ground and will not
operate.
10. Start the engine. While observing the voltage reading,
increase the engine speed to about 3000 RPM.
Readings of between 15 and 45 VAC are considered
normal.

Short Circuit Current (AC Amp Test)

1. Turn multitester dial to Aµ.
2. Connect red lead to 10A terminal.
3. Connect black lead to Com (--) meter terminal.
4. Disconnect lighting/charge coil wires from system.
Connect meter leads to coil wires leading to stator coils.
5. Start and idle engine. Readings should be above 5
amps. Refer to Amps AC on page 8.9.

Regulated Voltage

1. Connect the alternator to main harness connector.
2. Insert one of the tester leads along the side of the yellow
regulator wire connector between the insulation and the
terminal.
3. Ground the other tester lead.
4. Start engine and observe headlight output. Increase
engine RPM. If the headlights seem dim above 3500
RPM, let the engine return to idle and disconnect the
yellow wire from the regulator. Carefully observe the
voltage reading. Do not allow voltage to increase above
14.0 volts.
5. Slowly increase RPM. Voltage above 12 volts at 2500 -
3000 and a bright headlight, indicates a good lighting
coil. Voltage below 10 volts at 3000 indicates excessive
system loads, poor flywheel magnets, lighting coil
problems, or wires harness problems.
partially grounded (shorted) yellow wire.
6. Reconnect the yellow regulator wire and increase the
RPM. If the headlight was bright with the regulator
disconnected and dim when connected at the same
RPM, the regulator or regulator ground is at fault.
