Traction (Neutral) Switch Replacement 1. Remove the two wires that are connected to the traction switch. 2. Have a helper push the traction pedal down into either the FORWARD or REVERSE position; this will take the switch arm tension off of the switch. Loosen two (2) screws and remove the switch.

3. Install new switch. DO NOT over-tighten screws as the switch case could break. NOTE: Have a helper hold the traction pedal down while installing the switch. 4. Reconnect the two wires to the new switch. Make sure that one wire is connected to the “COMMON” terminal, and one wire is connected to the “NORMALLY OPEN” (N.O.) terminal. IMPORTANT: The traction switch has three (3) terminals. If the two (2) wires are not connected to the “COMMON” and “NORMALLY OPEN” (N.O.) terminals, the engine will be unable to start and the safety interlock circuit will not function properly.
