The Multiquip 40009500 Glow Switch Start E786 is a genuine OEM component designed for E786 series equipment. Sourced directly from Multiquip, this switch is built to the exact specification of the original part, ensuring correct operation of the glow start circuit every time. If your E786 is experiencing hard cold starts or a non-responsive preheat function, replacing this switch with the correct OEM part is the right first step. DHS Equipment stocks this part to get your machine back in service without guesswork.
Key Features
- Genuine OEM Electrical Specification — Manufactured to the exact resistance and switching output required by the E786 glow start circuit, not a generic approximation.
- Direct-Fit Installation — Matches the original connector, thread pitch, and panel cutout of the E786, so the switch seats and wires up the same way the factory unit did.
- E786 Series Compatibility — Confirmed fitment for E786 equipment; reference part 40009500 when ordering to ensure you receive the correct switch for your machine.
- Restored Cold-Start Performance — A functioning glow switch delivers consistent preheat signal to the glow plugs, allowing the engine to fire cleanly in cold or damp conditions where a failed switch leaves the engine cranking without heat.
- Electrical Integrity — As a switch in the glow plug circuit, correct contact rating and insulation grade matter — this genuine part meets those requirements, protecting the broader electrical system from overload or arcing caused by an undersized substitute.
The glow switch start controls the activation of the glow plug preheat system on diesel-powered equipment. When the operator engages the preheat function before cranking, this switch completes the circuit that sends current to the glow plugs, warming the combustion chamber and allowing the engine to start reliably in cold conditions. A worn or failed glow switch breaks that circuit, resulting in hard starts, excessive cranking, or a complete failure to fire — placing unnecessary strain on the starter motor and battery with every attempt.
