12-Volt Positive Ground Installation Instructions
For Part Number: 1544P12
CAUTION!!! Before installing, please read the following important information....
1. The Ignitor is designed for 12-Volt positive ground systems.
2. Leaving the ignition “ON” with the engine “OFF” for an extended period could result in permanent damage to
the Ignitor.
3. See Chart on back page for coil recommendations.
4. Four & Six cylinder engines require a minimum of 3.0 ohms of primary resistance. Do not remove resistors if
the coil primary resistance is less than 3.0 ohms.
5. If your Ignition coil has the recommended primary resistance, remove or bypass all external resistors.
DISASSEMBLY
1. PRIOR TO INSTALLATION TURN IGNITION SWITCH OFF OR DISCONNECT THE BATTERY
2. Remove the distributor cap, and rotor. Do not disconnect spark plug wires. Examine cap and rotor for wear
or damage. Replace as needed.
3. Disconnect the point wire from the negative (-) terminal of the coil.
4. Remove the point wire, point, and condenser from the distributor. The Ignitor does not require any
modification to the distributor. Therefore the point, condenser and hardware can be used as backup.
5. Clean all dirt and excess oil from the breaker plate and point cam.
IGNITOR INSTALLATION
1. Position the Ignitor over point pivot pin, align Ignitor plate to breaker plate screw hole. See figure 1.
2. Confirm that the Ignitor plate is flat and fits without modifications.
3. Fasten the plate into place using the provided screw.
4. Insert wires through the wire exit hole in distributor housing. Pull the rubber grommet into place. Make sure
wires do not interfere with any moving parts.
5. The magnet sleeve has green tape, DO NOT REMOVE IT!
6. Install magnet sleeve over the distributor shaft, onto point cam. Rotate the sleeve until a slight locating
position is felt before applying pressure. Press down firmly insuring sleeve is fully seated.
7. Module and magnet sleeve air gap is not adjustable.
8. Reinstall the rotor, and the distributor cap. Make sure all spark plug wires are securely attached.
9. See Wiring Instructions.

A. Recommended Wiring Installation:
The Ignitor ignition can be used in conjunction with most ignition coils rated at 1.5 ohms of primary resistance on eight cylinder
engines and 3.0 ohms on four and six cylinder engines. For optimum performance purchase and install the recommended
Flamethrower high performance coil.
Many vehicles came equipped with ballast resistor or resistance wire. To achieve optimum performance from the Ignitor ignition
system, we recommend the removal of these components. See last page for coil recommendations.
1. See figure A” for wiring diagram.
2. Remove the ignition switch wire from the negative coil terminal.
3. Connect the ignition switch wire directly to the Ignitor black wire.
Note: With the Ignitor electronic Ignition the Ignition switch wire
will no longer be connected to the coil.
4. Connect the Ignitor black/white wire to negative (-) side of the ignition
coil. Note: The Ignitor Black/White wire replaces the original
point wire.
5. Connect an insulated, AWG 20 copper stranded wire from the
positive coil terminal to the positive battery or chassis. Note: This wire
is not included in the kit.
6. Make sure all wires are connected correctly, and reconnect battery.
7. The engine can now be started. Let the engine run for a few minutes
and then set the timing in the conventional manner.
8. Start the engine and allow it to reach normal operating temperature.
Check ignition timing, and adjust to the desired setting.

B. Alternative Wiring Installation:
The Ignitor can also be installed in applications retaining the
ballast resistor. NOTE: Too much resistance in the circuit will
cause poor engine performance or no start condition.
1. See figure “B” for wiring diagram.
2. Remove the ignition switch wire from the negative coil terminal.
3. Connect the ignition switch wire directly to the Ignitor black wire.
Note: With the Ignitor electronic Ignition the Ignition switch
wire will no longer be connected to the coil.
4. Connect the Ignitor black/white wire to negative (-) side of the
ignition coil. Note: The Ignitor Black/White wire replaces the
original point wire.
5. Connect an insulated, AWG 20 copper stranded
wire from the positive coil terminal to one side of
the ballast resistor. Connect an insulated, AWG 20
copper stranded wire from the ballast resistor to the
positive battery terminal or chassis. Note: This wire
is not included in the kit.
6. Make sure all wires are connected correctly, and reconnect battery.
7. The engine can now be started. Let the engine run for a few
minutes and then set the timing in the conventional manner.
8. Start the engine and allow it to reach normal operating temperature.
Check ignition timing, and adjust to the desired setting.
