Electrical Resistance Tests (7000); Voltage Regulator Tests - Arctic Cat 2015 ZR 5000 Service Manual

Injection Coil
1. Test between the black/yellow and black wires from
the injection coil.
2. Resistance must be 3.6 ohms.
Fuel Injector
1. Disconnect the fuel injector wiring harness.
2. Test between the two injector terminals. Resistance
must be 9-12 ohms (5000) or 10.5-13 ohms (9000).
Coolant Temperature Sensor
1. Disconnect the coolant temperature sensor wiring
harness from the main harness.
2. Test the resistance between the two leads from the
sensor.
3. Compare the resistance reading to the Voltage/Resis-
tance Chart - Coolant Temperature in this section.
Air Temperature Sensor
 NOTE: The component temperature must be known
before conducting this test. Allow the engine to reach
room temperature.
1. Disconnect the wiring harness from the air tempera-
ture sensor.
2. Set the meter selector in the OHMS position and test
the sensor connector. Compare with the Voltage/
Resistance Chart - Air Temperature in this section.
 NOTE: The air temperature sensor utilizes a therm-
istor. Resistance will change as temperature varies.
Electrical Resistance
Tests (7000)
 NOTE: Replace any component that does not have a
test value within specifications. If the component
tests satisfactorily but is suspected to be faulty, con-
nect the red meter lead to a component lead and the
black meter lead to ground. Check for continuity
between the component and ground. If continuity is
observed, replace the component.
 NOTE: The following test should be made using
MaxiClips and the Fluke Model 77 Multimeter set to
OHMS scale.
CAUTION
Always disconnect the battery when performing resis-
tance tests to avoid damaging the multimeter.
Magneto Coil
1. Disconnect the three-white-wire connector.
2. Connect the red meter lead to one white wire; then
connect the black meter lead to another white wire (a
total of three tests).
3. Resistance must be 0.15-0.23 ohm.
Crankshaft Position Sensor
1. Disconnect the sensor.
134
2. Connect the red meter lead to the gray wire; then
connect the black meter lead to the black wire.
3. Resistance must be 336-504 ohms.
Ignition Coil
1. Disconnect an ignition coil connector.
2. Connect the red meter lead to the orange wire; then
connect the black meter lead to the other wire.
3. Resistance must be 1.19-1.61 ohms.
Injection Coil (1)
1. Test between the red/blue and the red/black wires
from the injection coil.
2. Resistance must be 86.4-105.6 ohms.
Injection Coil (2)
1. Test between the red/blue and the green/black wires
from the injection coil.
2. Resistance must be 86.4-105.6 ohms.
Injection Coil (3)
1. Test between the red/blue and the blue/black wires
from the injection coil.
2. Resistance must be 86.4-105.6 ohms.
Fuel Injector
1. Disconnect the fuel injector wiring harness.
2. Test between the two injector terminals. Resistance
must be 86.4-105.6 ohms.
Coolant Temperature Sensor
1. Disconnect the coolant temperature sensor wiring
harness from the main harness.
2. Test the resistance between the two leads from the
sensor.
3. Compare the resistance reading to the Voltage/Resis-
tance Chart - Coolant Temperature in this section.

1. Disconnect the wiring harness from the air tempera-
ture sensor.
2. Set the meter selector in the OHMS position and test

Voltage Regulator Tests

 NOTE: The following test should be made using
MaxiClips and the Fluke Model 77 Multimeter set to
DC Volt scale.
