Q) I have often wondered what the difference is between the red and yellow and the red and white wires on the HEI Super Coil. My friend said that one is more powerful than the other, is he correct? A) Actually, your friend is not correct. These two coils are very similar in appearance, perform identically, and can be installed in any integral coil distributor, but are of opposite magnetic polarity. This was done to match the high tension coil to the magnetic pick-up coil. The mis-application of these coils can cause hard or no starting, and/or backfiring while cranking.

Q) I have a late model LT1 Corvette and installed your 300+ custom fit kit. I must say what a difference! Especially the tremendous surge in power! But now my tach will not work properly. What can I do? A) On late model LT1 Corvettes, if the tach does not work properly you will need to remove the tach filter from the factory wiring harness. The factory tach filter will be located behind the drivers side head of the motor, or above the bellhousing behind the intake manifold. It will have one white wire running in and out of it, and usually looks like a small, square black box. Bypass the tach filter by clipping the filter out and reconnecting the wires and the tach should work.

Q) How do I install an HEI distributor in my '69 Chevelle and do away with my point type distributor? A) This is a very popular swap and simple to do if you follow a few guidelines. Install the HEI in place of the old distributor and connect the spark plug wires maintaining correct firing order sequence (ACCEL 8.8 spiral core recommended). Install the ignition coil into the distributor cap. There are two types of HEI coils, use the one with red and yellow leads (ACCEL #140003). The three wire connector from the base of the distributor plugs into the coil leads in the distributor cap. There will be two remaining connectors in the cap, (one from the coil's red wire and the other from the coil's yellow). Connect twelve volts from the key switch to the red lead (sometimes labeled "BAT") and the yellow lead which is for a tach signal if needed. CAUTION: Older vehicles used resistor wire or a ballast resistor to feed power to the ignition coil. This must be removed or bypassed. The HEI distributor requires a full twelve volts or damage to the control module will result. Maintain the engine's original initial timing and re-gap the spark plugs to .045".

Q) I just purchased an ACCEL super coil. Do I need to use the ballast resistor supplied? A) It depends on which ignition system its being used with. When using a single or dual point distributor, coil positive should be supplied with 8-10 volts with the key in the "run" position. Check it with a voltmeter and use the resistor only if necessary. Less than seven volts will result in a weak spark, and over ten volts will burn the points. Nearly all electronic ignitions require twelve volts (no resistor). This includes HEI, ACCEL, 41000 and 51000 series, and enhancer box systems (ACCEL 300+, Mallory HYFIRE®, MSD) an exception to this is the Mallory Unilite distributor when wired directly to the coil (no spark box). This required 7-9 volts supplied to coil positive. When using the supercoil with stock Chrysler or Ford Duraspark systems, use the ballast specified by the manufacturer.

Q) I am looking to upgrade my stock Chrysler coil. Can I use a super coil with my factory Chrysler electronic system? A) Yes, however ACCEL makes a coil matched to the Chrysler ignition box. Use coil #140305 for street applications and #140306 for drag race only.
|
|
Q) Drag race coils have more output voltage than a coil designed to be used on the street. Why can't I use a drag race coil on the street? A) While it is a higher output coil, it does create a lot of heat. It will burn out after extended periods of use. Drag Race coils are designed for shorts bursts of high energy and don't respond well to extended drive time.

Q) A friend tells me stainless steel/copper core ignition wires are the best. Is this true? A) While they have almost zero resistance and are excellent conductors of high current, they have no RFI suppression ability. This makes them impractical for use with nearly all electronic ignition systems, including HEI. Radio frequency interference (RFI) is induced into the atmosphere by high voltage passing through the solid core wires. This in turn has a "scrambling" effect on electronic modules, control boxes, rev limiters, radios, data acquisition systems, cell phones, computers, and garage door openers. Spiral core wires have the conductor wrapped around a fiberglass core, which has a canceling effect on RFI. Stainless steel solid core wire is only usable on point- type race engines, or some top fuel applications. For the lowest resistance wire with the highest current capacity, ACCEL 300+ race wire is the only serious choice.

Q) My electronic supercoil #140008 makes a "buzzing" noise. Is there something wrong with it? A) No. It is normal for the #140008 coil and also the 300+ box (#49320) to make this noise. The coil is not in oil, and transmits the noise through the housing. If the noise is unacceptable, either mount the unit in a different location or use a #49012 vibration mount kit.

Q) What are the advantages of the U-Groove spark plug design? A) U-Groove began production in 1969 and is the most copied feature on a spark plug today. Most spark plug manufacturers simply widened gap settings to increase the kernel of flame to burn the leaner fuel air mixtures. A negative effect of wider gaps was increased voltage required to fire. The U-Groove allows expansion room to allow a larger flame kernel while reducing voltage required to fire by maintaining the tolerance between center electrode and groundstrap. Reduced fouling potential is a function of the increased number of sharp edges on the ground electrode. A sharp edge collects fewer foul-causing deposits than the flat surface of a conventional electrode. The initial discharge of current from the center electrode is always from the outer circumference because the electrical energy is carried on the outside of the wire that is the center electrode. The U-Groove also "traps" some of the fuel air mixture directly in front of the initial kernel of flame eliciting faster starts and increased throttle response.

Q) What are the pros and cons of indexing spark plugs? A) Indexing spark plugs has not proven to make measurable performance difference. In the old days it was sometimes necessary to overcome erratic tolerances in cylinder head manufacturing.

|
Q) My 300+ box makes a clicking or buzzing sound. Does that mean its bad? A) The buzz from the 300+ is normal. It is a capacitive discharge ignition (C.D.I.) and when powered will emit an audible clicking which will change to a buzz as RPMs increase. This buzz can be particularly bothersome if the box has been mounted to the firewall or other steel body component. Using a rubber insulator or ACCEL Vibration Mount Kit (part # 49012) will absorb the vibration and quiet the noise created by the buzzing box.
|
|
Q) I just installed one of your 300+ Ignition Systems on my car. It runs just fine but the box makes a clicking noise, is there something wrong with it? A) The noise you hear is normal, the clicking sound is the capacitor inside the unit discharging each time a cylinder fires. To eliminate this you can use an Accel #49012 Rubber Mount Kit to isolate the box from vehicle.

Q) When do I need to use a ballast resistor with your coil? A) Anytime the primary resistance of a coil is below 1.0 ohms. You can check this by going from the positive and negative terminals on the coil using an ohms meter. Use of a ballast resistor is not required when running a CD box such as the ACCEL 300+ series or any of the Mallory HyFire systems.

Q) Do I need to run a ballast resistor when using your ACCEL 300+ ignition box? A) No, you do not run a ballast resistor when using our 300+ ignition box.
|
|
Q) Is your ACCEL 375+ control module a stand alone ignition box? A) No, the 375+ control module is a add on to the 300+ ignition box. The ACCEL 375+ Multi-Function Accessory control unit's harness plugs directly into the 300+ Ignition Control box harness, allowing the custom software and dual RISC microprocessors to fully interface with each other. This provides unparalleled capabilities and high-speed processing resulting in seamless performance. Now you have a system that has a two-step, timing retard, tach display, boost timing retard and map sensor capabilitites.
