The Multiquip SD135010921X9 Starter Switch Assembly SA6D170A is a genuine OEM component designed for the DCA600SPK ultra-silent diesel generator. As a direct Multiquip OEM replacement, this assembly is manufactured to the exact specifications of the original part, ensuring correct electrical operation and a seamless drop-in installation on DCA600SPK and SA6D170A equipped machines. Sourced directly through authorized Multiquip channels, SD135010921X9 is the correct part for operators who need a dependable, like-for-like repair.

Key Features

  • Genuine OEM Electrical Specification — Manufactured to the correct switching rating and circuit configuration required by the SA6D170A engine and DCA600SPK generator system, ensuring proper ignition sequence and load response.
  • Direct-Fit Installation — Engineered to match the original mounting footprint, connector type, and wiring harness interface, so the assembly seats and connects exactly as the factory unit did.
  • Confirmed Fitment for DCA600SPK — Verified for use on the Multiquip DCA600SPK ultra-silent generator with SA6D170A engine configuration.
  • Restores Clean Start Operation — A failed or worn starter switch can prevent the generator from cranking, cause intermittent start failures, or damage downstream electrical components; this OEM assembly restores full, reliable start-circuit function.
  • Electrical Safety Compliance — Using the correct OEM starter switch assembly on high-output generator equipment ensures the start circuit operates within designed voltage and current tolerances, protecting both the operator and the machine's electrical system.

The starter switch assembly controls the electrical signal that initiates the engine cranking sequence. When the operator turns the key or presses the start control, the switch assembly completes the circuit between the battery, control panel, and starter motor — allowing the engine to crank and fire. On a high-capacity generator like the DCA600SPK, a faulty starter switch can result in a no-start condition, erratic starting behavior, or unintended circuit activation. Replacing a worn or failed assembly with the correct OEM part restores predictable, safe start-up operation and protects the broader electrical system from irregular switching events.
