THROTTLE RELEASE SWITCH (TRS)
NOTE
Machines with Electronic Throttle Control (ETC) will not
have this switch.
The Throttle Release Switch (TRS) is designed to close
during throttle movement in the event the throttle cable
sticks or breaks.
When the throttle lever is at idle position, the TRS
contacts should be closed (touching). When the throttle
lever is moved the contacts will open and allow normal
operation. If the contacts remain closed or become
closed during throttle movement, the ECM will limit
engine RPM.
NOTE
The throttle cable must have the proper amount of free-
play adjustment. Refer to Chapter 2 “Throttle Cable
Adjustment” procedure.
