The Multiquip 1825530401 is a genuine OEM Starter Relay designed for the DCA-series ultra-silent diesel powered generators, including the DCA70USI, DCA36SPX, DCA45SSIU3, DCA45SSIU3-50HZ, DCA45SSIU3-60HZ, and DCA56SPX. As a direct OEM replacement, this relay is built to the exact electrical specification of the original component, ensuring correct circuit switching behavior and compatibility with the generator's start system. Sourced directly through Multiquip's authorized parts network, the part delivers the fit and function your DCA-series generator demands.
Key Features
- OEM-Spec Switching Capacity — Built to the precise coil voltage and contact rating of the original relay, ensuring the starter circuit engages and releases cleanly under load.
- Drop-In Connector Compatibility — Matches the original terminal layout and mounting footprint of the DCA-series generator's start circuit, so installation connects directly to existing wiring without adaptation.
- Broad DCA-Series Coverage — A single part number covers the DCA70USI, DCA36SPX, DCA56SPX, and DCA45SSIU3 (including 50Hz and 60Hz variants), making it a versatile stock item for fleet operators.
- Protects the Starter Motor — A correctly functioning relay isolates high-current starter draw from the control circuit. A failing relay can cause hard-start conditions, erratic cranking, or prevent the generator from starting altogether.
- Genuine Multiquip OEM Part — Authorized OEM replacement backed by Multiquip's parts program, giving you confidence that the component meets the same standard as the unit that left the factory.
The starter relay is an electromechanical switch that sits between the generator's ignition control circuit and the high-current circuit powering the starter motor. When the operator initiates a start, the relay's coil is energized, closing the contacts and allowing current to flow to the starter. Because it handles the heavy electrical load of engine cranking, the relay is subject to heat and contact wear over time. A worn or failed relay may cause the generator to crank intermittently, fail to start, or in some cases remain engaged — making timely replacement essential to keeping your DCA-series generator on power-call when it counts.
