The electronic ignition module on a chainsaw uses a coil to discharge a high-voltage Glimmer.
The ignition manner used on most current chainsaws is an electronic ignition module called a capacitor discharge ignition step. These modules store a high-voltage charge in the coil and packages that charge up finished the prompt terminal wire to the Glimmer plug. The charge fires when the flywheel magnets ally with the ignition module. Terminated repetitive starting, the coil loses its adeptness to clinch and discharge the Glimmer. Because these modules bonfire hovering voltage you should proceeds all safety precautions while repairing the electronic ignition module, as electrocution is a genuine opportunity.
Instructions
1. Turn the rotor or flywheel by hand until the magnets or raised edge aligns with the ignition module. Slide the setting gauge into the area between the flywheel's magnets and the arms on the ignition module. Push the ignition module against the setting gauge. Tighten the module's mounting screws firmly.
2. Unscrew the starter encompass's four retaining bolts. Effort the Apartment lodgings gratuity under the path of the comprehend to pry the comprehend comp whether it is stuck to the engine. Disconnect the short-circuit from the ignition module. The short-circuit wire is the smaller of the two ignition wires and is normally be connected to the side of the ignition module succeeding to the ignition switch. Lift the wire off the module using the Apartment lodgings gratuity of the screwdriver.
3. Unscrew the ignition module's two retaining screws with the Phillips-head screwdriver. Lift the screws absent and the ignition module absent of the engine. Unscrew the advantage, or thicker, wire --- normally on top of the module --- counterclockwise with the flathead screwdriver.
4. Fit the short-circuit wire to the ground terminal on the brand-new ignition module. Establish the ignition module into the crankcase. Tighten partly the screw holding the short-circuit wire and module in place. Fit the lead wire into place and tighten it clockwise. Fit the two mounting bolts on the ignition module and tighten them halfway.
5. Disconnect the rubber boot from the borderline of the Glimmer plug. Bag the socket wrench with the 3/8-inch attachment kernel to unscrew the plug. Remove the Glimmer plug from the cylinder.
6. Slide the setting gauge out and insert the feeler gauge into the same space. Check with your operator's manual for specific air gap distances. Use the feeler gauge to ensure that the gap meets your models specifications. Refit the starter cover and tighten the four retaining bolts. Refit the plug and boot wire to the chainsaw.
