Tether Switch Test (Accessory Option)
1. Disconnect wire harness from switch.
2. Connect an ohmmeter across switch contacts. The circuit
should have an open line or infinity reading.
3. Pull tether boot from switch and check for continuity
between switch contacts. Replace switch if there is no
continuity or greater than .5 ohms resistance.
Electronic Throttle Control (ETC) Switch
The Electronic Throttle Control (ETC) system is designed to
stop the engine of an ATV in the event of a mechanical problem
with the throttle mechanism. The ETC switch is mounted
independently of the throttle actuator lever inside the throttle
block assembly. This is a
normally closed switch, and is held in
the open position (contacts are separated (as shown below)) by
throttle cable tension. The contacts are “open” during normal
operation regardless of throttle lever position. In the event of a
mechanical problem in the throttle mechanism (cable tension is
lost), the switch contacts close, connecting the CDI black wire
to ground, which prevents ignition spark. This is the same as
turning the key or engine stop switch “OFF”.
Test the ETC switch at the harness connector.
NOTE: Adjust throttle cable freeplay (ETC switch)
and make sure throttle mechanism is functioning
properly before testing the switch. Refer to
Maintenance Chapter 2 for cable adjustment
procedure.
ETC Operation Test
Remove throttle block cover by carefully releasing all tabs
around edge of cover.
Place transmission in neutral and apply parking brake.
Start engine and open throttle lever slightly until engine RPM is
just above idle speed.
Hold throttle cable with fingers at point “A” as shown below and
release throttle lever. If the ETC system is functioning properly,
the engine will lose spark and stop.
