TRS SWITCH OPERATION OVERVIEW
The Throttle Release Switch (TRS) switch 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 switch
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.
