9-20 ELECTRICAL SYSTEM IGNITION SYSTEM Engine stop switch ECM Side- #1 stand Power source relay circuit CKP #2 sensor Fuse Waveform arrangement Ignition circuit #3 switch CPU #4 Fuse Waveform arrangement circuit CMP Battery sensor TP ECT GP sensor sensor switch E NOTE: L The fuel cut-off circuit is incorporated in this ECM in order to prevent over-running of engine. When engine P speed reaches 13 300 r/min, this circuit cuts off fuel at the fuel injector. But under no load, the clutch lever is pulled or the gear position is neutral, this circuit cuts off fuel when engine speed reaches 12 900 r/min. M E-03, 33, 24: The circuit cuts off the ignition primary current for all spark plugs.  A Under no load, the engine can run over 12 900 r/min though the ignition cut-off circuit is effec- S tive, which may possibly cause engine damage. Do not run the engine without load over 12 900 r/min at anytime.
