VTS Switch
SPX, GSX Limited and XP Limited
Always confirm first that the fuse is in good con-
dition.
Disconnect BLACK wire, BLUE/WHITE wire and
GREEN/WHITE wire of VTS switch.
Using a multimeter, connect test probes to switch
BLACK and BLUE/WHITE wires; then, connect
test probes to switch BLACK and GREEN/WHITE
wires.
Measure resistance; in both test it should be high
when button is released and must be close to
zero when activated.
VTS Motor
SPX, GSX Limited and XP Limited
Always confirm first that the fuse is in good con-
dition.
Motor condition can be checked with a multime-
ter. Install test probes on both BLUE/ORANGE
and GREEN/ORANGE wires. Measure resistance,
it should be close to 1.5 ohm.
If motor seems to jam and it has not reached the
end of its stroke, the following test could be per-
formed.
First remove motor, refer to VARIABLE TRIM SYS-
TEM 09-05. Then manually rotate worm to verify
VTS system actuating mechanism for free opera-
tion.
Connect motor through a 15 A fuse directly to the
battery.
Connect wires one way then reverse polarities to
verify motor rotation in both ways.
If VTS actuating mechanism is correct and the
motor turns freely in both ways, VTS module
could be defective.
If VTS motor does not stop at the end of its stroke
while installed, the motor could be defective.

VTS Control Module
SPX, GSX Limited and XP Limited
It receives its current from the battery. It is pro-
tected by its own 7.5 A fuse.
RESISTANCE TEST
Disconnect BROWN/BLACK wire and BROWN/
WHITE wire of VTS control module.
Connect test probes of a multimeter to BROWN/
BLACK wire and BROWN/WHITE wire of VTS
control module.
NOTE: To permit VTS actuation when engine is
not running, remove safety lanyard from switch
and depress start/stop button to activate MPEM
timer.
Push on VTS switch down position until motor
stops.
Read the resistance on the ohmmeter, it should
indicate a resistance of 24 ohms ± 1%.
Push on VTS switch up position until motor stops.
Read the resistance on the ohmmeter, it should
indicate a resistance of 167 ohms ± 1%.
RESISTANCE (Ω)
167 ± 1%
24 ± 1%
NOTE: If the VTS control module passes this re-
sistance test, it doesn't mean it is in perfect con-
dition.
