Brakelight Switch (Handlebar Control); Coolant Temperature And Cooling Fan Switches - Arctic Cat 650 Twin2004 Service Manual

Brakelight Switch
(Handlebar Control)
The switch connector is the two-prong black connector
in front of the steering post. To access the connector,
the front rack and front fenders must be removed (see
Section 8).

NOTE: The ignition switch must be in the ON
position.
VOLTAGE
(Wiring Harness Connector)
1. Set the meter selector to the D.C. Voltage position.
2. Connect the red tester lead to the orange wire; then
connect the black tester lead to ground.
3. The meter must show battery voltage.

NOTE: If the meter shows no battery voltage,
troubleshoot the battery, fuse, switch, or the main
wiring harness.

NOTE: If the meter shows battery voltage, the
main wiring harness is good; proceed to test the
switch/component, the connector, and the switch
wiring harness for resistance.
RESISTANCE
(Switch Connector)
! CAUTION
Always disconnect the battery when performing
resistance tests to
multimeter.

NOTE: The brake lever must be compressed for
this test. Also, the ignition switch must be in the
OFF position.
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to one black wire; then
connect the black tester lead to the other black
wire.

Coolant Temperature
and Cooling Fan
Switches
1. Connect the meter leads (selector in the OHMS
position) to the switch contacts.
2. Suspend the switch and a thermometer in a
container of water; then heat the water.

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 coolant temperature switch when the water
temperature reaches 112°-118° C (234°-244° F)
the meter should read a closed circuit.
