Description
Overview:
This Wiring Harness & Switch Assembly is a complete electrical loom with keyed on/off switch for Yanmar L‐Series single‐cylinder diesel engines, such as the L100 and 186F. Built with copper conductors and PVC insulation inside a protective black outer sheath, it links the engine's charging coil (3 A dynamo), regulator/rectifier (3 A), and ancillary circuits to a robust key switch. The assembly provides reliable routing of power and clean switching of the engine electrics to support dependable starting and shutdown. Supplied with two keys, it is a practical, long‐life replacement when refurbishing small plant and garden equipment powered by Yanmar L‐Series engines. Identified by MPN 320 358, it is sized and terminated to suit common L‐Series layouts for straightforward fitment and consistent performance.
