  • Question
    What is the Test procedure for checking my Unilite electronic ignition module’s operation?
    Answer

    INSTRUCTIONS
    • Remove both the distributor cap and rotor, then turn the ignition ON but DO NOT START car.
    • Now connect your Red voltmeter wire to the NEGATIVE terminal (-) on the coil, by attaching the Red lead wire clip from voltmeter to the (-) terminal.
    • Next attach your Black voltmeter wire to an engine ground on a good ground source. We suggest a manifold, or header bolt. Most anywhere on the engine is good.
    • Now the voltage should read about 11 to 12 volts at this point. Remember to turn the key on for this reading! 12 volts must be present on your voltmeter.
    • Next, place a credit card down into the distributor, blocking the 2 photo optic eyes on top the module facing each other on the top. With eyes blocked, the volts should drop way down below 2 volts or less. This drop is a must! If the voltage drops down to anything under 2 volts, then the module is good and ready to use. If the voltage does NOT drop, the module will need to be replaced.
    • This damage could have been caused by many things, such as: power surge from an alternator, high resistance spark plugs and plug wires, improper ground wires, if someone has given you a jump, if you have given someone a jump, or battery chargers, which can also damage ignition modules. If voltage always stays below 2 volts and never increases up to 11-12 volts, then the module has been spiked by high voltage and needs to be replaced.

    NOTE: The lack of a ballast resistor will cause this type of spike. If the voltage only drops down to 3-4 volts, this will produce a weak spark: too weak to run engine and the module will need to be replaced.

  • Question
    What is the difference between coils #8140 and #8145 and should I use a ballast resistor?
    Answer
    The 8140 has 1.4 OHMs primary resistance and will need a ballast resistor when used with a point style distributor. The 8145 has 0.7 OHMs primary resistance and will require a ballast resistor when used with a Unilite or MBI distributor.

  • Question
    What spark plug gap should I use when using the ACCEL HEI coil?
    Answer
    .045 is a good starting point. Check your plugs after 100 miles of driving. The white porcelain around the electrode of a properly gapped plug should have khaki tan coloration. If the plugs look black, close the gap by .005 to .040. If the porcelain is white, open the gap by .005 to .050 to cool the operating temperature of the plug.

  • Question
    What HEI distributor coil do you recommend for my ACCEL HEI unit?
    Answer
    You will need to look at your original coil. If you have red and yellow OEM primary wires, use ACCEL #140003. If you have red and white OEM primary wires, use ACCEL #140005.

  • Question
    Why is my Mallory electric fuel pump fluctuating in pressure and jumping all over?
    Answer
    There are many things that could cause this issue. The top offenders include using the wrong size fuel pressure regulator, not using a return line, or having a return line that is too small. Other causes could include using too many 90° degree elbows, an improperly sized fuel pump is the wrong size for the engine Horsepower or using a return line out of the pump.

  • Question
    Does Mallory sell an electronic distributor conversion kit to do away with my points set up?
    Answer
    YES, there are two (2) choices of kits to choose from when purchasing our conversion kit. First, you will need to know what kind of distributor you have now. If it is a Mallory, we will need the Mallory Part number #. The kits are called "E-Spark" conversion kits or "Unilite" conversion kits.

  • Question
    What is the Replacement Ignition Module and pick up coil for my Mallory HEI distributor?
    Answer
    There are two types of Mallory HEI Distributors: 75 series and 85 series units. The 75 series HEI uses a Module with a Rev-limiter - Module Part #699. The 85 series HEI uses the Module Part #607.
    NOTE: Pick-up coils for the HEI distributors are NOT available as replacement parts.

  • Question
    What’s the part number for replacement cap and rotor on my Mallory Comp 9000 distributor?
    Answer
    The Comp 9000 distributors is an older design that we sold prior to the UNILITE. The replacement cap and rotors are available for sale and must be bought to match the distributor part number #. If you contact us with your distributor part number we can match the cap and rotor to his Comp 9000 distributor.

  • Question
    Where do I need to connect the 3 colored wires (Red, Green and Brown) on a Unilite distributor?
    Answer
    The Green wire connects to the Negative (-) coil terminal. The Red wire connects to the Positive (+) coil terminal, and the Brown wire connects to a good engine ground. The brown wire must be ground to the engine.

  • Question
    What coil should I use for my Mallory Unilite distributor, and/or Mallory Hyfire CD ignition box?
    Answer
    All Unilite distributors need coils with a minimum amount of 1.4 Ohms primary resistance. Coils are 12 volts; however, they do have different amounts of primary resistance, which is measured in Ohms. You can still use a coil with less than 1.4 Ohms, but you must install a Ballast Resistor (Mallory #700) between the coil and the distributor, install on Red wire coming out of the Unilite distributor. It is Important to know that the Unilite distributor will work initially on the engine with less than 1.4 Ohm, BUT NOT FOR LONG. It only takes a short period of time to burn up the module using a coil with the wrong resistance.
    When you select a coil for any High power CD ignition box like the Mallory Hyfire CD boxes, the Mallory Hyfire CD boxes MUST always use a coil with LESS than 1 Ohm of primary resistance.

  • Question
    Do I use a ballast resistor with ACCEL Super Coil #140001?
    Answer
    Yes, you will need a ballast resistor when using ACCEL Super Coil #140001 with a Unilite or MBI distributor. To use with a points style distributor, additional resistance is needed to get to 3.0 OHMs.
