12-Volt Positive Ground Installation Instructions
For Part Number: 1244AP12
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. Rotor tension spring must be removed from distributor shaft in order to remove dust shield.
4. Disconnect the point wire from the negative (-) terminal of the coil.
5. 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.
6. Clean all dirt and excess oil from the breaker plate and point cam.
IGNITOR INSTALLATION
1. Determine the rotation of your distributor rotor. The Ignitor can be installed in clockwise or counter clockwise positions.
2. Install Ignitor plate using the screw hole stamped for the correct rotation. “CC” indicates the correct screw hole for
counter clockwise rotation. “C” indicates the correct screw hole for clockwise rotation.
3. Fasten the Ignitor plate to the distributor beginning with the correctly stamped screw hole. Two screws must be used.
4. Install grommet into hole in the side of the distributor body. The wire length inside the distributor can be adjusted by
gently pulling one wire at a time through the grommet. CAUTION: care must be taken to insure wires do not interfere
with moving parts.
5. Install magnet sleeve over distributor shaft, onto point cam. Rotate sleeve until a slight locating position is felt before
applying pressure. With sleeve lined up on point cam, press down firmly insuring sleeve is fully seated.
6. Module and magnet sleeve air gap is not adjustable.
7. Reinstall dust shield, rotor spring tension clip, and rotor. NOTE: SOME APPLICATIONS REQUIRE THE
INSTALLATION OF THE DUST SHIELD TO INSTALL THE DISTRIBUTOR CAP. THE CENTER HOLE OF THE DUST
SHIELD MUST BE ENLARGED TO CLEAR THE MAGNET SLEEVE.
8. Install 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.
