The Multiquip 21785 Kill Switch Harness Magura Model 90 is a genuine OEM kill switch harness designed for CA4HC and CA5BC series Whiteman walk-behind power trowels. This is a direct Multiquip OEM replacement component, sourced and supplied to the exact specifications of the original part installed at the factory. Verified fitment covers the C and CA Series walk-behind trowels, including CA4HC and CA5BC models. Installing the correct harness ensures the kill switch circuit operates as intended, maintaining safe and reliable operator control over the machine.
Key Features
- Genuine OEM Electrical Integrity — Manufactured to Multiquip's original wiring and connector specifications, ensuring correct circuit continuity and switch response for the Magura Model 90 kill switch system.
- Direct-Connect Replacement — Engineered to plug directly into the existing Magura Model 90 kill switch assembly on C and CA Series trowels, requiring no splicing or connector modification.
- Confirmed Fitment for CA4HC and CA5BC — Verified for Whiteman walk-behind power trowel models CA4HC and CA5BC, so you can order with confidence.
- Preserves Kill Switch Function — A damaged or failed harness can prevent the kill switch from cutting the engine on demand; replacing it restores full operator control of engine shutdown.
- Operator Safety Circuit Component — The kill switch harness is a critical link in the machine's emergency stop system; using the correct OEM harness ensures the safety circuit performs to its original design intent.
The kill switch harness connects the operator-activated kill switch to the engine's ignition circuit, allowing the machine to be shut down immediately when the switch is triggered. On walk-behind trowels, this circuit is a key part of the operator safety system — if the harness is damaged, corroded, or has a broken connection, the kill switch may fail to stop the engine when needed. Replacing a worn or faulty harness with the correct Multiquip 21785 restores the integrity of the shutdown circuit and keeps the trowel operating safely.
