Fuses; Electronic Speedometer Speed Sensor - Arctic Cat 700 Diesel ATV 2007 Service Manual

NOTE: When testing the HI fuse holder, the
headlight dimmer switch must be in the HI posi-
tion; when testing the LIGHTS fuse holder, the
headlight dimmer switch can be in either position.
NOTE: If the meter shows no battery voltage,
troubleshoot the battery, switches, distribution
module, or the main wiring harness.
! CAUTION
Always disconnect the battery when performing
resistance tests to avoid damaging the multimeter.
1. Set the meter selector to the OHMS position.
2. Connect the red tester lead to one spade end of the
fuse; then connect the black tester lead to the other
spade end.
3. The meter must show less than 1 ohm resistance.
If the meter reads open, replace the fuse.
NOTE: Make sure the fuses are returned to their
proper position according to amperage. Refer to
the fuse block cover for fuse placement.

Speed Sensor
NOTE: Prior to testing the speed sensor, inspect
the three-wire connector on the speed sensor for
contamination, broken pins, and/or corrosion.
1. Set the meter selector to the DC Voltage position.
2. With appropriate needle adapters on the meter
leads, connect the red tester lead to the voltage
lead (V); then connect the black tester lead to the
ground lead (G).

3. Turn the ignition switch to the ON position.
4. The meter must show 6 DC volts.
5. Leave the black tester lead connected; then con-
nect the red tester lead to the signal lead (S) pin.
6. Slowly move the ATV forward or backward; the
meter must show 0 and 6 DC volts alternately.
NOTE: If the sensor tests are within specifica-
tions, the speedometer must be replaced. See Sec-
tion 9.
To replace a speed sensor, use the following proce-
dure.
1. Disconnect the three-wire connector from the
speed sensor harness or from the speed sensor;
then remove the Allen-head cap screw securing
the sensor to the sensor housing.
2. Remove the sensor from the sensor housing
accounting for an O-ring.
3. Install the new speed sensor into the housing with
new O-ring lightly coated with multi-purpose
grease; then secure the sensor with the Allen-head
cap screw (threads coated with blue Loctite #242).
Tighten securely.
