Multiquip 0601831585 Preheat Button

The Multiquip 0601831585 Preheat Button is a genuine OEM component designed for DCA series ultra-silent and super-silent diesel generators, including the DCA70SSIU, DCA70SSJU, DCA125SSJU, DCA150SSJU, DCA220SSVU, DCA85SSJU, DCA100SSJU, DCA56SPX, and related variants. As a direct OEM replacement, this button is built to the exact specification of the original part installed at the factory, ensuring proper fitment and correct operation within the generator's cold-start system. Sourced directly from Multiquip, part 0601831585 is the correct choice for technicians and fleet managers maintaining DCA series equipment to the original design standard. DHS Equipment stocks genuine Multiquip parts so you can get the right component and get your generator back in service without second-guessing compatibility.

Key Features

• Genuine OEM Construction — Manufactured to the original electrical and mechanical specification for the preheat circuit, ensuring the button actuates with the correct resistance and switch action for reliable cold-start engagement.
• Direct-Fit Replacement — Matches the original mounting footprint and connector interface on DCA series generator control panels, dropping into place without modification to the panel or wiring harness.
• Broad DCA Series Compatibility — Confirmed fitment across a wide range of Multiquip ultra-silent and super-silent generators, including DCA70, DCA85, DCA100, DCA125, DCA150, and DCA220 model families.
• Cold-Start System Integrity — A properly functioning preheat button ensures the glow plug circuit activates fully before cranking, protecting the diesel engine from hard starts and premature wear in cold conditions.
• Electrical Safety in High-Demand Applications — On generator sets running critical or continuous loads, a correctly rated preheat switch prevents unintended circuit behavior that could disrupt startup sequences or damage ignition-adjacent components.

The preheat button activates the glow plug system on diesel-powered generators, warming the combustion chambers before the engine is cranked. This pre-warming step is essential in cold ambient temperatures, where a diesel engine without adequate preheat may fail to start or start roughly, placing unnecessary stress on starter components and the engine itself. When the preheat button fails — through a broken switch mechanism, loss of electrical contact, or housing damage — the glow plugs will not receive the activation signal, making cold starts difficult or impossible and potentially leaving a generator offline when it is needed most.
