Before installing, please read the following important information....
1. The Ignitor is designed for 12-volt Positive ground systems.
2. See Chart on back page for coil recommendations.
3. The Ignitor is compatible only with a “resisted style” coil. Eight cylinder engines require a minimum
of 1.5 ohms of resistance. Six & four cylinder engines require a minimum of 3.0 ohms of resistance.
4. If your Ignition coil has the proper primary resistance, remove or bypass all external resistors.
Note:
Do not remove resistors if the coil primary resistance is lower than specified.
5. The black wire from the Ignitor must be connected to the ignition switch wire.
6. The black/white wire must be connected to the negative (-) side of the coil.
7. Some magnet sleeves may have green tape,
DO NOT REMOVE IT.
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.
