82 1100 asp. spark ignitor?

Post by shermanator » Mon Feb 06, 2012 11:20 pm

I believe the spark ignitor is located by the two spark units. Is this correct? What is the function of the spark ignitor? Im new to all this so bear with me . appreciate the help

The spark ignitors are up near the coils, over the carbs, at the front of the engine.

They are the transistorized ignition, which replace the points used on earlier Goldwings. Points (which are basically switches) open and close with the rotation of the engine, providing a pulse of 12 volt power to the ignition coils (where the pulses are converted to many thousands of volts to create spark on the spark plugs). On the GL1100, there are pickup coils, that generate a very small pulse (perhaps a few volts, and very few milliamps) as the engine rotates. This pulse is transferred to the ignitors, which are basically transistors. They amplify the small pulses generated by the pickup coils and use those small pulses to generate 12 volt pulses with much larger current. These larger pulses then travel to the coils where they are amplified into thousands of volts for the spark plugs.

The advantage is that there are no moving parts - it's transistorized ignition, as opposed to the mechanical points system used in earlier bikes.
