The Ignitor can also be installed in applications retaining the ballast resistor or resistance wire.
1. Attach the Ignitor black wire to the negative coil terminal. (See Figure B)
2. Attach the Ignitor red wire to the ignition side of resistance, or any 12 volt ignition power source. (See Figure B)
3. Check to insure that the polarity is correct, and that all connections are tight.
4. Re-connect the battery.
5. Start the engine and allow it to reach normal operating temperature. Check ignition timing, and adjust to the desired setting.
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.
• To remove a ballast resistor, (normally white ceramic blocks 3 to 4 inches long), disconnect all wires on both ends of the ballast
resistor. Remove the resistor from the vehicle and splice the disconnected wires together at a single point.
• To remove a resistance wire, trace the coil power wire, which was previously connected to the positive coil terminal, back to the fuse
block. Bypass this wire with a 12-gauge copper stranded wire.
1. Attach the black Ignitor wire to the negative coil terminal. (See Figure A)
2. Attach the red Ignitor wire to the positive coil terminal. (See Figure A)
3. Check to insure that the polarity is correct, and that all connections are tight.
4. Re-connect the battery.
5. Start the engine and allow it to reach normal operating temperature. Check ignition timing, and adjust to the desired setting.

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. Part Number LU-165P12, place Ignitor over eccentric screw, rotate if necassary to line up holes
on breaker plate. Note: Ignitor mounts over condenser original location. Do not use point pivot pin,
it’s not used for Ignitor installation. See Figure 1. Secure Ignitor with screws provided.
2. Part numbers LU-143P12 & LU-144P12, Install Ignitor over point guide pin, line up point screw
hole and secure with screw provided.
3. All Other kits, Install Ignitor adapter plate to the breaker plate using the screws provided. NOTE:
25D and 22D distributors will use both mounting screws, 23D distributors will use one flat head
mounting screw. Place the Ignitor module on the adapter plate studs. Secure module to adapter
plate with the nuts provided.
4. 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.
5. Module and magnet sleeve air gap is not adjustable.
