Coils: "New York" Master Vibrator
Here's one of many different accessory master vibrator coils offered for the model T.
"Notice that when using a master vibrator, the act of shorting the points across on each coil then also shorts across the internal capacitor in that coil. If you plan on using a master vibrator with a set of coils, you need not remove a defective internal capacitor that might be found inside one of the individual coils since it will be shorted out when the coil is used with a master vibrator. The master vibrator has the capacitor inside it and that one capacitor is used in turn by each coil as it is fired. The use of a common set of points and a common capacitor results in a much better balance of the ignition firing but of course the master vibrator points will need to be replaced 4 times as often compared to coil points. The later KW master vibrator with the later points is a much better design than the other types. (John Regan)"
