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: 1864A & 1864LA
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.
5. The Ignitor does not require any modification to the distributor. Therefore the point, condenser and hardware
can be used as backup. Note: 1864A & 1864LA require a minor modification. See Figure 1.
6. Clean all dirt and excess oil from the breaker plate and point cam.
IGNITOR INSTALLATION
1. Part numbers 1864A & 1864LA modification required. (See Figure 1).
2. Remove module from adapter plate before proceeding to next step.
3. Place adapter plate over point pivot pin, line up adapter plate to screw hole on breaker plate.
Confirm
that the adapter plate is flat and fits without modifications and fasten the plate into place using the screw
provided.
4. Place the Ignitor module on the adapter plate studs. Secure module to adapter plate with the nuts and lock
washers provided.
5. If the distirbutor 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
distirbutor housing. See Figure 1.
1864A & 1864LA
Grind away or cut corner of bracket for
magnet sleeve clearance.
Point Cam
Figure 1
6. 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.
7. 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.
8. Module and magnet sleeve air gap is not adjustable.
9. Reinstall the rotor, and the distributor cap. Make sure all spark plug
wires are securely attached.
10. See Wiring Instructions.
