How does a Model T buzz coil work?
It is simply a roller that is rotated by the engine’s camshaft around the inside of a cap that is deceptively like a distributor cap. As it rolls across each contact, the connected coil is powered and consequently starts buzzing giving a shower of sparks.
Can a bad ignition coil cause vibration?
Misfiring Engine If an ignition coil is not working properly, your engine will likely misfire. A misfiring engine results in a jerking or sputtering feel when you are moving at normal speeds. When you stop, a misfire from a bad ignition coil may cause your vehicle to run roughly, vibrate or shake.

How many volts does a Model T coil produce?
As Warren points out the HCCT generates AC voltage just like the car and ranges from a low point (when the coil will operate) of 2 volts to over 7 volts. Because of engine speed the car magneto voltage is higher at 7 volts to over 30 volts in many cases.
