1. The Ignitor is designed for 12-Volt negative 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.
6. The Ignitor is compatible as a trigger for most electronic boxes.

For Part Number: LU-165
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. Place Ignitor over eccentric screw, rotate if necessary to line up holes on breaker plate. Secure Ignitor with
screws provided. Note: Ignitor mounts over condenser original location. Do not use point pivot pin, it’s not
used for Ignitor installation. See Figure 1.
2. 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.
3. Vacuum advance distributors only: If the distributor ground wire was removed during the installation process
be sure it is re-attached securely. NOTE: If the ground wire is missing, one needs to be installed and attached
from the point breaker plate to the distributor housing.
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.
6. Reinstall the rotor, and the distributor cap. Make sure all spark plug wires are securely attached.
7. See Wiring Instructions.
