Start-In-Gear Relay - Arctic Cat Altera 300 Service Manual

KM458A
3. Turn the ignition switch to the ON position. The
meter must read battery voltage.
NOTE: If battery voltage is not shown on the meter,

troubleshoot the battery connections, ground connec-
tions, and starter cable connections.
4. With the transmission in neutral, depress the starter
button. There should be an audible "click" from the
starter relay and the meter should show 0 DC volts.
If the meter indicates as specified, replace the starter.
If there is no audible click and meter reads battery
voltage, proceed to step 5.
5. Disconnect the two-wire connector on the starter
relay pigtail from the main harness; then on the har-
ness side, connect the red tester lead to the yel-
low/red wire and the black tester lead to the
yellow/green wire.
6. With the transmission in neutral, depress the starter
button. The meter must read battery voltage. If bat-
tery voltage is indicated, replace the starter solenoid.
If no voltage is indicated, troubleshoot the gear posi-
tion switch, starter button, ignition switch, or harness
connectors.
COOLANT TEMPERATURE AND
COOLING FAN
1. Connect the meter leads (selector in the OHMS posi-
tion) to the switch contacts.
2. Suspend the switch and a thermometer in a container
of cooking oil; then heat the oil.
NOTE: Neither the switch nor the thermometer

should be allowed to touch the bottom of the con-
tainer or inaccurate readings will occur. Use wire
holders to suspend switch and thermometer.

3. On the cooling fan switch when the temperature
reaches 86-90° C (187-194° F), the meter should
read a closed circuit. On the coolant temperature sen-
sor when the temperature reaches 120° C (218° F),
the meter should read 16.0 ohms.
4. Allow the oil to cool. On the cooling fan switch
when the temperature is within a range of 80-85° C
(176-185° F), the meter should read an open circuit.
On the coolant temperature sensor, monitor the tem-
perature and resistance as the oil cools. At 100° C
(212° F) the meter should read 27 ohms, at 80° C
(176° F) 52 ohms, and at 50° C (122° F) 154 ohms.
5. If the readings are not as indicated, the switch must
be replaced.
6. Install the switch and tighten securely.
7. Connect the switch leads.

Start-in-Gear Relay

 NOTE: The relay schematic is embossed on the
relay housing for testing continuity.
NOTE: The module and wiring harness are not a

serviceable component and must be replaced as an
assembly.
TESTING
The start-in-gear relay is located under the seat behind
the fuse block. To test the relay, use the following proce-
dure.
1. Turn the ignition switch to the ON position; then
compress the brake lever or depress the auxiliary
brake pedal. There should be an audible "click" from
the start-in-gear relay.
 NOTE: The brakelight should illuminate whenever
either brake is applied. If the brakelight does not illu-
minate, troubleshoot the respective brakelight switch.
2. Apply the opposite brake from step 1. There should
be an audible "click" from the start-in-gear relay.
3. Disconnect the four-wire connector from the
start-in-gear relay; then using a voltmeter, connect
the red tester lead to the green/yellow wire (1) and
the black tester lead to the green wire (3).
