Controller-To-Engine Brake Actuator Voltage; Output-To-Actuator Voltage - Arctic Cat 650 Twin2004 Service Manual

3. If battery voltage is not present, check the 30-amp
fuse, ignition switch, or wiring harness.
Controller-to-Engine
Brake Actuator Voltage
1. Support the ATV on a stand or suitable jack so the
wheels are off the ground; then select D.C. Voltage
on the multimeter (B). Connect the red tester lead
to the brown/white wire terminal (15) and the
black tester lead to the black wire terminal (10) in
the controller (A).
2. Turn the ignition switch ON and spin a rear wheel
in the forward direction; then allow the wheel to
stop. After at least one second, turn the ignition
switch OFF.
3. After two seconds, observe the meter until the
actuator stops. The controller output voltage
should vary from 5-12 D.C. volts. If the voltage is
not within specifications,
forward/reverse detecting sensor. If the sensor is
normal, replace the actuator controller.

multimeter.
1. Disconnect the sensor lead wire connector (A);
then select OHMS on the multimeter and check
resistance between the sensor pins. The meter
ATV2144
should read 1200-1600 ohms.
2. Check each lead of the sensor to ground. The
meter should show an open circuit or infinity (∞).
If either test fails, replace the sensor (B).

ATV2145 Select D.C. Voltage on the multimeter (B) and turn the
ignition switch ON; then connect the red tester lead to
the black/green wire terminal (2) and the black tester
lead to the black wire terminal (10) in the controller
(A). The controller output voltage should be 4.8 ± 0.2
D.C. volts. If the reading is not as specified, replace
the actuator controller.
