Controller-To-Engine Brake Actuator Voltage (650 V-Twin); (650 V-Twin) - Arctic Cat 400 Service Manual

1. Select DC Voltage on the multimeter (B); then
turn the ignition switch ON.
2. In the brake controller (A), connect the red tester
lead to the orange wire terminal (9) and the
black tester lead to the black wire terminal (10).
The meter should read battery voltage.
3. If battery voltage is not present, check the
30-amp fuse, ignition switch, or wiring harness.
Controller-to-Engine
Brake Actuator Voltage

(650 V-Twin)

1. Support the ATV on a stand or suitable jack so
the wheels are off the ground; then select DC
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 termi-
nal (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 DC volts. If the voltage is
not within specifications, check the for-
ward/reverse detecting sensor. If the sensor is
normal, replace the actuator controller.

Resistance
(650 V-Twin)
NOTE: This component is located on the left side
of the engine and provides vehicle direction data
to the engine brake controller.
! CAUTION
Always disconnect the battery when performing
resistance tests to avoid damaging the multimeter.
1. Disconnect the sensor lead wire connector (A);
then select OHMS on the multimeter and check
resistance between the sensor pins. The meter
should read 1200-1600 ohms.
2. Check each lead of the sensor to ground. The
meter should show an open circuit or infinity
( 4 ). If either test fails, replace the sensor (B).
