Reversing the Red and Black ignition wires will destroy the ignition module and void the warranty. Using a coil with too little primary resistance can cause the ignition module to overheat and fail, thus voiding the warranty.

How to install your electronic ignition kit:

    1. Unclip your distributor cap.
    2. Remove the points and condenser base plate from the distributor.
    3. Remove the rotor arm by pulling upwards.
    4. Replace the original base plate with our electronic ignition base plate. Do not screw it down yet.
    5. Place the new trigger ring over the central distributor shaft ensuring a tight fitment. Do not force the trigger ring on too hard.
    6. Replace the original rotor arm. Ensure that it can rotate on the shaft, and the trigger ring is close to the new electronic ignition kit base plate but not touching as it rotates.
    7. Run the wire around the back of the kit making sure the wires can’t snag on anything when the distributor and rotor arm rotate.
    8. Once you are happy the clearances are all OK, fix down the new base plate using your original screws.
    9. Replace your distributor cap.

Negative Earth:

  • Powerspark red wire goes to Positive (+ VE, SW, or 15) on ignition coil.
  • Powerspark Blackwire goes to Negative (- VE, CB, or 1) on ignition coil.

The Powerspark module is designed for 6v -12V negative ground applications only.

To ensure the life of the kit it is advisable to have silicon or resistive HT leads (if you currently have copper).

We can supply these leads. Click here to browse our range.

If you can’t get the ignition to work once installed, try these suggestions:

  1. Condenser and wires from distributor should not be installed in vehicle once the new electronic kit is in place.
  2. Check the coil resistance prior to fitting this unit to ensure that your coil has a resistance of more than 1.5 ohms.
  3. Check which terminal on the coil your live ignition feed is, ensure this is +’ve on the coil not -‘ve.
  4. Connect the Black wire to the coil negative ( -ve, or 1) terminal.
  5. Connect the Red wire to the coil positive ( + or 15) terminal.

For testing purposes, no other wires should be attached to the coil terminals, except for the center HT lead to the distributor cap.

Check the condition of the cap and rotor arm (replacing them if possible for testing).

If you have a positive ground vehicle you will need to either convert to negative ground or have one of our Positive Earth Powerspark kits.


You can set the timing dynamic with a strobe light with points ( engine running ) and with electronic system you can do the same.

You can set the timing approx as before static, and you will need a strobe light ie + and –ve to strobe and sensor lead to No1 plug lead to set the timing dynamic and then adjust to max @ 3500 rpm say 24 degree (depends on the vehicle and engine).

The electronic ignition module is mounted as near as possible to the same position as the points were, but in some cases the distributor will possibly have to be turned +/- 10 degrees from where it was with points.

Setting the timing is recommended once you have fitted one of our electronic kits. Setting by dynamic is the best and most accurate way to adjust the timing.

Battery voltage to coil:

With ignition switch ON, engine not running, check voltage at coil + terminal. The voltmeter should read somewhere around +11 to +14 volts.

If voltage is too low or there’s no reading, the battery terminal or ground connection may be corroded and need cleaning or the battery may need charging.

Some vehicles have a resistor wire running from the ignition switch to the coil +ve terminal. This resistor wire drops the voltage below 9 volts so you may need to run a non-resistor wire from the ignition switch to the coil + terminal or run a +12V wire directly from the ignition switch to the red wire of the Simonbbc ignition module.

Make sure that the ignition switch terminal to which you connect this wire has power only when the ignition switch is in the ON position. Or you can, for temporary testing purposes only, run a wire directly from the battery’s + terminal to the coil + terminal, the Simonbbc ignition red wire to the coil + terminal and the black wire to the coil -ve terminal.

Do not leave the wire from the battery connected to the coil + terminal for more than a minute or so without the engine running

Gap between the black trigger and the ignition module:

If you need to increase the air gap slightly, hold ignition base plate away from distributor shaft while tightening set screw and/or loosen the two screws and retighten screws while lightly prying ignition module away from the magnet sleeve.

Do not over-torque the screws!

The black magnet sleeve should not rub against red ignition module, but exact gap is not critical. It may be necessary to gently pry red ignition module away from black magnet sleeve to keep them from rubbing together.


Standard Lucas or Bosch coil or one of our standard points type coils is recommended. The Simonbbc negative earth module red wire connects to positive ( + or 15 on Bosch coil). The black wire connects to negative ( –ve or 1 on Bosch coil). The coil should have a minimum of 1.5 Ohms internal, primary resistance. For positive earth we have a separate instruction set.

Measuring Primary Resistance:

Label and remove all wires to coil. Using a digital multimeter in the 200 Ω mode, measure between coil’s + and – terminals. Allow a few seconds for the reading to settle.

For best performance, the coil should have a minimum of 7,000 Ohms secondary resistance (measured from coil’s + or – terminal to center high tension terminal, in the 20K Ω mode of the Ohmmeter)

Vehicle System Voltage:

If the charging system voltage, measured at the coil’s positive terminal, is more than 14.2 volts at 2,500+ RPM, the voltage regulator may need replacing. Too much voltage can damage the ignition module and other electronic components. A maximum charging system voltage of 13.5 volts is adequate.

Jump-starting the vehicle:

Use caution when jump-starting a vehicle fitted with our electronic kit.

Connect the battery’s + terminal to the other vehicle’s battery + terminal. Connect the negative (black) part of the jumper cable to engine ground points, such as a bolt on the engine block, on both vehicles.

Do not turn the ignition switch to the ON position while the vehicle at the other end of the jumper cables is running. Charge your vehicle battery with the other vehicle or with a battery charger and then remove the jumper cables or charger before turning on the ignition switch and starting your vehicle.

If the ignition switch is in the ON position while both vehicles are running, the electrical surge resulting from both vehicles’ charging systems being connected together with jumper cables could be enough to destroy the ignition module and/or other any electronic components.

If you are still not able to get the supplied ignition module to function then please call the technical team for assistance or email, we will be happy to help.
