"Shower of Sparks"
Starting vibrators, available in 12 and 24 volt models, eliminate the need for impulse couplings used on many magnetos.
The vibrator provides interrupted battery voltage to the magneto primary coil. This pulsating DC voltage is stepped up by the transformer action, producing a shower of sparks at the spark plug for improved starting. CMI Master Service Manual X43003, 3-3
