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.

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.
5. 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
7. Install adapter plate onto breaker plate, install module on top of adapter plate.
See figure 1 & 2. Confirm
that the adapter plate and module assembly is flat and fits without modifications. Fasten the plate into place
using the provided screw.
8. 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 module plate to
the distributor housing.
9. Insert both wires through the wire exit hole and pull the grommet into place. Check to insure that the wires
do not contact any moving parts.
10. Install magnet sleeve over distributor shaft, onto point cam. Rotate sleeve until a slight locating position is
felt before applying pressure. With the sleeve lined up on point cam, press down firmly insuring sleeve is
fully seated.
11. No air gap adjustments required.
12. Replace the rotor and distributor cap. Make sure all spark plug wires are securely attached.
13. See Wiring Instructions.
