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 cap screw (threads coated with
blue Loctite #242). Tighten securely.

RPM Limiter
NOTE: The ROV is equipped with an ECM that cuts
fuel spray and spark when maximum RPM is
approached. When the RPM limiter is activated, it
could be misinterpreted as a high-speed misfire.
Ignition Switch
To access the ignition switch, dash switches, front acces-
sory connectors, and front switched accessory connector,
the dash must be unfastened and slid to the rear.
VOLTAGE
NOTE: Perform this test on the harness connector.
1. Set the meter selector to the DC Voltage position.
2. Connect the red meter lead to the red wire; then con-
nect the black meter lead to battery ground.
3. Meter must show battery voltage.
NOTE: If the meter shows no battery voltage, trou-
bleshoot the main 30 amp fuse, the battery, or the
main wiring harness.
4. Connect the red meter lead to the red/black wire;
then with the black lead grounded, turn the ignition
switch to the ON position. The meter must show bat-
tery voltage.
5. Connect the red meter lead to the yellow/green wire;
then with the black lead grounded, turn the ignition
switch to the START position. The starter should
engage and the meter must show battery voltage.
NOTE: When the starter is engaged, battery voltage
will be approximately 10.5 DC volts.
Headlight Switch
VOLTAGE
1. Connect the red meter lead to the gray wire; then
connect the black meter lead to the black wire.
2. Turn the ignition switch to the ON position. The
meter must show battery voltage.
NOTE: If the meter does not show battery voltage,
troubleshoot the LIGHTS fuse on the power distribu-
tion module, the ignition switch, or the main harness.
3. Connect the red meter lead to the yellow wire; then
select the high beam position on the headlight
switch. The meter must show battery voltage.
4. Connect the red meter lead to either of the two white
wires; then select the low beam position on the head-
light switch. The meter must show battery voltage.
NOTE: The battery voltage will show lower in steps
3 and 4 due to electrical loading of the headlights.
