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