The accompanying diagram shows a simple circuit which can be used in four ways for engine ignition:

A. When plugged into a 120 volt outlet, terminals 1 and 13 will provide 6 volts AC for a Model T Ford coil.

B. Terminals 2 and 3 will provide 10 volts DC to operate a high tension breaker point ignition system; or, of course a Ford coil if you want to use it on DC.

C. Terminals 3 and 4 will provide power for a igniter, and the lamp will indicate when the igniter contacts are closed. This gives an easy check on the operation of the igniter.

D. If you desire to operate on battery, two size 'D' flashlight cells connected to terminals 2 and 3 will provide a good spark for an igniter. Be sure to observe polarity when connecting to these terminals. .

T Filament transformer, primary 117 volts, secondary 12.6 volts center tapped, 2 amperes, Stancor No. P8130

DI Diode, the one that I used was from a Ford alternator

R Resistor, 1 ohm, 10 watt

LT Lamp, No. 43, 3.5 volts

F Fuse, No. AGC 3, 3 amps

CAP Capacitor, Mallory No. 202040 8 ET-AL, 4000 Mfd, 10 working volts

L Filter choke, Stancor No. C 2685, .035 Hys at 2 amperes DC, .75 ohms DC res.

The components listed are the ones that I used, but others having equal characteristics can be used. If you have to buy all new material, the cost will be approximately $40.00.
