The Yamaha 2A7-85580-20-00 Pulser Coil Assembly provides crankshaft position sensing and ignition triggering for Yamaha ignition systems. Engine-mounted, it outputs electrical pulse signals that drive ignition timing for motorcycles, scooters, and other engine-powered equipment requiring precise timing control. Built as an industrial-grade coil assembly, it replaces or retrofits in Yamaha timing systems and is compatible with Yamaha ignition platforms; common replacements include Yamaha 2A7-85580-10-00, Yamaha 2H7-85580-20-00, and Yamaha 3Y1-85580-20-00.
