PerTronix 1281P6 User Manual
6-Volt Positive Ground Installation Instructions
For Part Number: 1281P6
CAUTION!!! Before installing, please read the following important information....
1. The Ignitor is designed for 6-Volt positive 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 0.6 ohms of primary resistance. Do not remove resistors if the
coil primary resistance is less than 0.6 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. 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
1. Insert the Ignitor black and red wires through the distirbutor housing verifying the grommet is seated
properly.
2. Install the Ignitor module using the provided hardware in the same manner as a set points. NOTE: 1281 kits
use the points adjustment screw hole as a pilot for the Ignitor locating pin. Confirm the mounting plate is flat
and fits without any modifications. See Figure 1.
3. 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
distirbutor housing. See Figure 1.
4. Place the magnet sleeve over the distributor shaft, and onto point cam. Press down firmly to insure magnet
sleeve is fully seated. NOTE: Make sure that the Ignitor module and magnet sleeve are level. See Figure 2.
5. Set the air gap between the module and magnet sleeve using the provided plastic feeler gauge (0.030”
thick). This done in the same manner as points.
6. Reinstall the rotor, and the distributor cap. Make sure all spark plug wires are securely attached.
7. 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. See last page for coil recommendations.
1. See figure A for wiring diagram.
2. Remove the ignition switch wire from the negative coil terminal.
3. Connect the black Ignitor wire directly to the ignition switch wire.
4. Connect the Ignitor black/white wire to negative (-) side of the ignition coil.
5. Connect an insulated, AWG 20 copper stranded wire from the positive coil terminal to the positive battery or chassis. Note: This wire
is not included in the kit.
6. Make sure all wires are connected correctly, and reconnect battery.
7. The engine can now be started. Let the engine run for a few minutes and then set the timing in the conventional manner.
8. 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. NOTE: Too much resistance in the circuit will cause poor
engine performance or no start condition.
1. See figure B for wiring diagram.
2. Remove the ignition switch wire from the negative coil terminal.
3. Connect the black Ignitor wire directly to the ignition switch wire.
4. Connect the Ignitor black/white wire to negative (-) side of the ignition
coil.
5. Connect an insulated, AWG 20 copper stranded wire
from the positive coil terminal to one side of the
ballast resistor. Connect an insulated, AWG 20 copper
stranded wire from the ballast resistor to the positive
battery terminal or chassis. Note: This wire is not
included in the kit.
6. Make sure all wires are connected correctly, and reconnect battery.
7. The engine can now be started. Let the engine run for a few minutes
and then set the timing in the conventional manner.
8. Start the engine and allow it to reach normal operating temperature.
Check ignition timing, and adjust to the desired setting.
