dropped. Also if the connector is disconnected when current is flowing, the excessive
voltage may damage the module.
• A faulty ignition system is often related to poor connections. Check those connections before proceeding.
• Use spark plug of the correct heat range. Using spark plug with an incorrect heat range can damage the engine.
• For alternator and ignition pulse generator removal and installation, see section 10.
