The Multiquip AT141011 Heater Relay 4045TF150 DCA70SSJU is a genuine OEM component designed for the DCA70SSJU ultra-silent diesel generator series. As an authorized Multiquip part, AT141011 is produced to the exact electrical specification required by the 4045TF150 engine system, ensuring correct switching behavior and circuit protection in the field. This relay is a direct OEM replacement sourced through DHS Equipment, giving you confidence that you are installing the correct part for your DCA70SSJU generator.
Key Features
- Correct Switching Specification — Rated and wound to the precise coil and contact specification required by the 4045TF150 engine heater circuit, ensuring proper activation and load handling.
- Genuine OEM Component — Manufactured to Multiquip's original design, this relay matches the exact form and connector interface of the part it replaces on DCA70SSJU generators.
- DCA70SSJU Fitment — Confirmed compatible with the DCA70SSJU ultra-silent generator, a John Deere 4045TF150-powered unit in the DCA series.
- Protects the Heater Circuit — A correctly functioning relay ensures the engine block or intake heater energizes and de-energizes on schedule; a failed relay can prevent cold-weather starting or leave the heater circuit permanently energized.
- Electrical Safety Compliance — Using the specified OEM relay maintains the integrity of the generator's electrical control circuit, preventing unintended load conditions on adjacent components.
A heater relay controls the flow of electrical current to the engine's block heater or intake air heater, acting as an electrically operated switch that engages and disengages the heater element based on signals from the control system. On diesel-powered generators like the DCA70SSJU, reliable heater operation is critical for cold-start performance and engine longevity. When the relay fails — whether through contact wear, coil burnout, or corrosion — the heater circuit becomes inoperative or erratic, leading to hard starts, excessive engine wear during cold cranking, or potential overload of downstream wiring.
