PerTronix 1143N6 User Manual

6-Volt Negative Ground Installation Instructions

For Part Number: 1142N6 & 1143N6

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

1. The Ignitor is designed for 6-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 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.

DISASSEMBLY

1. PRIOR TO INSTALLATION TURN IGNITION SWITCH OFF OR DISCONNECT THE BATTERY

2. Check distributor rotation before disassembly. 1142 Ignitor kits are designed for Clockwise rotating
distributors and 1143 kits for Counter Clockwise rotating distributors.

3. Remove the distributor cap, and rotor. Do not disconnect spark plug wires. Examine cap and rotor for wear
or damage. Replace as needed.

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

5. 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.

6. Clean all dirt and excess oil from the breaker plate and point cam.

IGNITOR INSTALLATION

1. Position the Ignitor over point pivot pin and

eccentric adjustment screw, rotate eccentric screw as needed
to line up screw hole to breaker plate screw hole. Confirm that the Ignitor plate is flat and fits without
modifications. Fasten the plate into place using the original point screw.

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. 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.

4. Module and magnet sleeve air gap is not adjustable.

5. Reinstall the rotor, and the distributor cap. Make sure all spark plug wires are securely attached.

6. See Wiring Instructions.

A. Recommended Wiring Installation:

The Ignitor ignition can be used in conjunction with most ignition coils rated at 0.6 ohms of primary resistance on eight cylinder

engines and 1.5 ohms on four and six cylinder engines. For optimum performance purchase and install the recommended

Flamethrower high performance coil.

Many vehicles came equipped with ballast resistor or resistance wire. To achieve optimum performance from the Ignitor ignition

system, we recommend the removal of these components.

• To remove a ballast resistor, (normally white ceramic blocks 3 to 4 inches long), disconnect all wires on both ends of the ballast

resistor. Remove the resistor from the vehicle and splice the disconnected wires together at a single point.

• To remove a resistance wire, trace the coil power wire, which was previously connected to the positive coil terminal, back to the fuse

block. Bypass this wire with a 12-gauge copper stranded wire.

1. Attach the black Ignitor wire to the negative coil terminal. (See Figure A)

2. Attach the red Ignitor wire to the positive coil terminal. (See Figure A)

3. Check to insure that the polarity is correct, and that all connections are tight.

4. Re-connect the battery.

5. Start the engine and allow it to reach normal operating temperature. Check ignition timing, and adjust to the desired setting.

B. Alternative Wiring Installation:

The Ignitor can also be installed in applications retaining the ballast resistor or resistance wire.

1. Attach the Ignitor black wire to the negative coil terminal. (See Figure B)

2. Attach the Ignitor red wire to the ignition side of resistance, or any 6-volt ignition power source. (See Figure B)

3. Check to insure that the polarity is correct, and that all connections are tight.

4. Re-connect the battery.

5. Start the engine and allow it to reach normal operating temperature. Check ignition timing, and adjust to the desired setting.
