The Multiquip 1734163020 Magnetic Switch Assembly D1403 is a genuine OEM component designed for D1403 series equipment. As a factory-sourced part, it meets the exact electrical and mechanical specifications required for proper operation in the D1403 application. This assembly ensures correct engagement of the starting circuit, restoring full electrical control to your machine. DHS Equipment supplies this part direct so you can get your equipment back up and running without compromise.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the exact coil resistance, contact rating, and switching capacity required for the D1403 application — no guesswork on compatibility.
- Direct Assembly Replacement — Supplied as a complete switch assembly, connecting directly to the existing wiring harness and mounting points for a straightforward swap.
- Confirmed D1403 Fitment — Verified for use on D1403 series equipment; cross-reference part number 1734163020 against your machine's parts manual before ordering.
- Consistent Starting Circuit Performance — A correctly functioning magnetic switch delivers full current to the starter motor on demand; a worn or failed switch causes no-start conditions or erratic engagement.
- Electrical Safety Integrity — As a switching component in the ignition and start circuit, using a genuine OEM assembly ensures proper contact closure and reduces the risk of arcing, overheating, or unintended circuit activation.
A magnetic switch assembly — sometimes called a starter solenoid or contactor — acts as a high-current relay between the ignition control circuit and the starter motor. When the operator engages the start switch, the magnetic switch closes its heavy-duty contacts to deliver battery voltage directly to the starter, enabling engine cranking. Over time, the internal contacts can pit, burn, or fail to close fully, resulting in a clicking sound, slow cranking, or a complete no-start condition — replacing the assembly restores proper starting function and protects the starter motor from voltage irregularities.
