12-Volt Negative Ground Installation Instructions

For Part Number: 1183

CAUTION!!! Before installing, please read the following important information....

CAUTION!!! Before installing, please read the following important information....

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. Eight cylinder engines require a minimum of 1.5 ohms of primary resistance. Do not remove resistors if the
coil primary resistance is less than 1.5 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 distributor cap and rotor from distributor. Do not disconnect the spark plug wires from cap. Examine
parts for excessive wear. Replace as needed

3. Disconnect the point wire from the negative (-) terminal of the coil.

4. Remove the point wire, points, 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. Single Point Distributors only. (Dual Point Distributors Go To Step 2)

• Install the Ignitor adapter plate over the point pivot pin and over the eccentric screw (point adjustment
screw), rotate eccentric screw if necessary to properly align adapter plate to screw hole on breaker plate.

• For Clockwise distributors see figure A.

• For Counter Clockwise distributors see figure B.

• Use the provided screw to hold the plate in place.

• Install the Ignitor module onto the adapter plate. Use the provided screws to hold the module in place. Do
not over tighten.

• Vacuum advance distributors only:

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.

If the distributor ground wire was removed during the installation process

• Go to step 3.

2. Dual Point Distributors only:

• Install the Ignitor adapter plate over the point pivot pin and over the eccentric screw (point adjustment
screw), rotate eccentric screw if necessary to properly align adapter plate to screw hole on breaker plate.

• Clockwise distributors see figure C.

• Counter Clockwise distributors see figure D.

• Use the provided screw to hold the plate in place.

• Install the Ignitor module onto the adapter plate. Use the provided screws to hold the module in place. Do
not over tighten.

• 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.

3. Feed the two terminal ends of the wire through the hole in the distributor housing. Pull the grommet into
place.

4. Adjust the wire length inside the distributor so that it does not interfere with moving parts.

5. Place the magnet sleeve over the distributor shaft, and onto point cam. Press down firmly to insure magnet
sleeve is fully seated.

6. Air gap between module and magnet sleeve is not adjustable.

7. Look at figure E & F to determine the proper installation for the spacer ring.

8. Re-install the rotor and the distributor cap. Make sure all spark plug wires are securely attached.

9. See wiring instructions.

Figure F
Distributor shafts without a raised step
above point cam require that spacer
ring to be installed with the step
portion of the spacer ring facing down.

Figure E
Distributor shafts with raised step above
point cam require that spacer ring to
be installed with the step portion of the
spacer ring facing up.
