The Multiquip 20514 Kill Switch Wire Assembly is a genuine OEM component designed for BS46H, JS36H, CS24H, B46, J36-M30, and HDA-Series power trowels. This is the factory-correct wiring assembly that connects the operator kill switch circuit, ensuring the engine shutdown system functions exactly as Multiquip engineered it. Sourced direct from Multiquip, part 20514 is built to match original harness routing, connector type, and wire gauge — no splicing or adaptation needed at installation.
Key Features
- Genuine OEM Electrical Specification — Correct wire gauge, connector terminals, and insulation grade matched to the original Multiquip kill switch circuit — not a generic wire substitute.
- Drop-In Harness Replacement — Connector ends are factory-matched to the kill switch and ignition kill terminals on covered trowel models, allowing straightforward plug-in reinstallation.
- Broad Trowel Compatibility — Fits a wide range of Multiquip and Whiteman walk-behind and ride-on power trowels including BS46H11, BS46H90, JS36H55, JS36H90, CS24H55E, B46, B46S90, J36-M30, and HDA-Series machines.
- Engine Shutdown Integrity — A worn or broken kill switch wire can prevent the engine from shutting off when the operator releases the handle — replacing it restores the critical safety shutdown function the machine depends on.
- Operator Safety Circuit Compliance — The kill switch assembly is a core element of the trowel's operator presence control system; using the correct OEM replacement ensures the circuit performs to its original design intent.
The kill switch wire assembly carries the electrical signal from the operator-controlled kill switch to the engine's ignition system, cutting power to the spark plug and stopping the engine when the switch is activated or the operator loses control of the handle. On walk-behind and ride-on power trowels, this circuit is part of the operator presence safety system — if the wire becomes frayed, corroded, or disconnected, the engine may fail to shut down on command, creating a serious hazard on the finishing deck. Replacing a damaged or faulty assembly with the correct OEM part restores the full, reliable function of the engine stop system and keeps the trowel operating safely and as designed.
