The Model T Ignition Coil

The vibrator ignition coil system did not originate with the Model T, nevertheless; the Model T was its most famous application. In this and the following two articles we will attempt to comprehensively present the story of the Model T ignition coil. Part 1 presents a brief history of the Model T ignition coil beginning with the evolu-

This is a quick video showing how cool these early model T coils are, ... Testing a Ford Model T Buzz Coil and Making it Buzz Again Part 2 of 3 - Duration: 5:06.

To complete installation just follow the wiring diagram using your model coil and battery. We suggest using the Exciter model coil and a miniature sealed lead-acid . Model T Buzz Coils. Hello, I've just picked up my first hit and miss engine a FM Z 1 1/2 hp. The coil has all screw terminals and are marked B, T and S.

A trembler coil or vibrator coil is a type of high-voltage ignition coil used in the ignition system of early automobiles, most notably the Benz Patent-Motorwagen and the Ford Model T. Its distinguishing feature is a vibrating magnetically-activated contact called a trembler or interrupter, which breaks the primary current, generating multiple sparks during each cylinder's power stroke.

Figure 8 is a diagram depicting the second set of measurements. The test set up is unchanged and the intervals of timer segment and timer case movement are the same. When taking these measurements a properly rebuilt Model T coil was electrically connected to the timer, magneto and spark plug and the engine rotated at Ignition 3

I don't think that 12V will hurt a "T" buzz coil as long as there is a spark plug gap of .050 or less in the secondary circuit. Model T engines had an internal low-tension AC magneto that, at speed would put out around 30V. Doing the calculations gives an equivalent to approximately 20V DC.

These coils perform as sweet as they look. To make connection to the Model T style buzz coil easier and reliable we built these "special" coils with brass binding posts where the contacts normally are and then label those contacts with S, T, and B lettering to indicate Spark plug, Timer, and Battery wire connections.

MODEL T HARNESS WIRING DIAGRAMS By Bob Cascisa Version 1.0 04-07-2019 • Here are wire harness electrical drawings for the 1919 – 1927 model T’s. • They are intended to show electrical inter-connections of the harness assemblies. • These drawings reflect the harness assemblies that are currently available from Model T suppliers.

Re: Don't use 12 volts Norm: I don't think that 12V will hurt a "T" buzz coil as long as there is a spark plug gap of .050 or less in the secondary circuit. Model T engines had an internal low-tension AC magneto that, at speed would put out around 30V. Doing the calculations gives an equivalent to approximately 20V DC.

Initial offering will consist of ready-to-use Buzzcoil PC board assembly complete with pigtail leads. To complete installation just follow the wiring diagram using your model coil and battery. We suggest using the Exciter model coil and a miniature sealed lead-acid battery, both which are available through us if desired.
