Forklift Timer Relay KQ1-DC12V 91306-05700 – Mitsubishi K3A K3B K3C K3D 12V

Forklift Timer Relay KQ1-DC12V 91306-05700 5650-043-1762-0 — 12V Timer Relay for Mitsubishi K3A/K3B/K3C/K3D Diesel Engines

This forklift timer relay covers three interchangeable part numbers — KQ1-DC12V, 91306-05700, and 5650-043-1762-0 — and is a Kingstream OEM 12V timer relay designed specifically for Mitsubishi K3A, K3B, K3C, and K3D industrial diesel engines used across forklifts, excavators, tractors, loaders, bulldozers, trucks, sweepers, and generators. The timer relay is a critical component in the Mitsubishi K-series engine management system, controlling time-dependent functions such as glow plug preheating duration, automatic engine shutdown delay, and accessory power retention after key-off. The Mitsubishi K3 engine family — a ubiquitous inline industrial diesel engine platform powering equipment from multiple OEMs including Mitsubishi Forklift Trucks, Caterpillar compact equipment, and various Asian-manufactured construction machinery — uses this specific timer relay for its cold-start and shutdown logic. A failed timer relay on a Mitsubishi K3 engine causes hard cold starting (preheating circuit inoperative), the engine continuing to run after key-off (shutdown circuit failed), or intermittent electrical faults that are difficult to diagnose because the timer relay operates only during transitional states. Kingstream OEM quality with high-quality construction. 1-year warranty with neutral packing. MOQ 1 piece with payment by T/T, L/C, MoneyGram, PayPal, or cash. Standard wooden case packing or customized packaging available. 1.5kg gross weight with 10×10×10cm compact packaging.

Installing the 91306-05700 timer relay on a Mitsubishi K3 engine requires locating the relay on the engine electrical panel or in the engine bay relay box. The K3-series engines are used across multiple equipment types with varying relay locations — on forklifts the relay is typically on the firewall or engine-side relay bracket, while on excavators and loaders it may be in a sealed electrical enclosure. Before removing the old relay, verify the replacement part number matches one of the three cross-referenced numbers (KQ1-DC12V, 91306-05700, or 5650-043-1762-0). The relay socket pinout is standardized — photograph or label the wire positions before disconnection. After installation, test the cold-start sequence by turning the ignition to ON without cranking: the glow plug indicator should illuminate for the specified preheat duration. Test the engine shutdown function by turning the key to OFF and verifying the engine stops within the normal delay interval. 1-year warranty with genuine or OEM parts quality.
