MULTI-SPARK
SINGLE OR DOUBLE FIRE
ELECTRONIC IGNITION SYSTEM FOR
HARLEY-DAVIDSON MOTORCYCLES

 SPARK PLUG WIRES
Choice of spark plug wires is an important consideration when using an electronic ignition system. You must use carbon core resistor spark plug wires. Solid or Spiral wound wires will damage the ignition module and void the warranty!

SPARK PLUGS
You must use a resistor spark plug with electronic ignitions. Stock spark plugs are resistor type plugs and will work. Spark plug gap should be limited to as small as possible, while still maintaining performance.

A wide spark plug gap can cause the following problems: Hard cold starting, misfires during rich or lean fuel conditions, and reduction of upper rpm range.

Initial settings for spark plug gaps are:
Single plug Multi-Spark 0.028-0.032
Dual plug Multi-Spark 0.025-0.030

Many things effect spark plug gap settings:
Compression Ratio: The higher the engine compression, the more voltage required to fire the plug, and the narrower the plug gap should be.
RPM: The higher the rpm's the less time the coil has to charge to break over voltage or complete saturation. A narrower spark plug gap will help high rpm stability.
Multi-Spark: To maintain a good secondary spark within a wider rpm range it is wise to run a narrower spark plug gap. It is better to precisely place two stable, consistent sparks than to fire one wider spark that may cause misfires in rich or lean conditions, or from any of the above reasons.

For your information/Tech Tips
When using the Quick Time Method the typical start-up (static timing) is set at 5° BTDC, the ignition starts a 5° then after approximately 3 revolutions of the crank the ignition advances to 25°. As set from the factory the ignition will advance to 35° at 2100 RPM's. If the static timing is set a 0°, then after approximately 3 revolutions of the crank, the ignition advances to 20°. As set from the factory the ignition will advance to 30° at 2100 RPM's.

starting: if you experience kick back on the starter you are too far advanced at startup, retard the module CCW or check the advance SET adjustment to see if it is set at 2100 RPM's or higher.

If the engine starts hard & idle is low you may be too far retarted at startup and may need to advance the module CW.

If you experience pinging in the midrange,  raise the VOES set point to 5-5.5" lbs or retard the module.

                       INSTALLATION INSTRUCTIONS
WARNING: DO NOT TOUCH COIL OUTPUT WIRE ( BLACK) TO +12 VDC. DO NOT USE SOLID OR SPIRAL WOUND SUPPRESSION SPARK PLUG WIRES, USE RESISTOR WIRES ONLY. FAILURE TO OBSERVE THESE PRECAUTIONS WILL DAMAGE MODULE & VOID THE WARRANTY.
IMPORTANT: Disconnect battery ground during installation. Do not hook up the coils until the very last thing.
     1 Remove all components from the ignition cone cam cover area, exposing the cam shaft end. Install the rotor cam shaft end, aligning the notch on rotor with cam notch & attach with supplied washer & screw. If you have a stock module leave it mounted in place, but disconnect it from
the coil, tachometer and ignition switch wire.
     2. Pull ignition wire through wire hole & rock ignition into cone. The STATIC TIMING LED at top & quick time arrow pointing forward at hold down screw. In the case of a sportster everything is rotated 90° clockwise with LED facing forward and hold down screws in the vertical position.
     3. Insert the rear lock down screw, point the timing line on ignition as shown in the Quick Time method centered of the front lockdown screw, insert front lock down screw & tighten both.
     4. Hook ignition positive (red) wire to the ignition supply, usually at the coil positive (center terminal) is best with the kill or ignition switch wire.
     5. Hook the white ignition wire to the tach trigger wire of motorcycle (usually pink) if used.
     6. Hook the greeen front cyclinder trigger wire to the front coil   the brown wire to the rear cylinder coil. If you wish to use the ignition in the dual fire mode with a dual fire coil, connect the green & brown wires together and hook to the coil trigger (see dual fire wiring diagram).
     7. Hook the Blue  VOES wire to VOES switch. It is recommended that you use a VOES switch if one was on your motorcycle or you should add one if you have a high performance, heavy bike or have wide engine load variations. If you did not have a VOES ground the blue wire.
     8. Reconnect battery ground.

QUICK TIME METHOD:
Place timing line as shown in drawing below so that it points to dead center of the front hold down screw. The timing will be set at approximately 5° BTDC static 35° total timing. If pointed approximately 1/16" below (clockwise) of dead center of front hold down screw. Timing will be set at approximately. 10° BTDC static 40° total timing..
In the case of a sportster everything is rotated 90° clockwise with LED facing forward and hold down screws in the vertical position.

TOP DEAD CENTER TIMING METHOD:
Turn the engine over to the TDC mark of the compression stroke on the fly wheel. With the power on (+12 VDC ), rotate the trigger plate all the way clockwise. Next, rotate the trigger plate (CCW) counterclockwise until the red LED static timing light on the #1 (front cylinder) trigger just begins to light. Lock down the trigger plate hold down screws. Recheck engine TDC mark to make sure no movement has occurred. Peg #1 will be set at approximately 8° BTDC. Additional adjustments may be made to meet your engines specific requirements.

USE ONLY RESISTOR (CARBON CORE) SPARK PLUG WIRES & RESISTOR SPARK PLUGS.

DO NOT USE SPIRAL WOUND SUPPRESSION OR SOLID TYPE
SPARK PLUG WIRES!

STOCK SPARK PLUG WIRES ARE
CARBON CORE WIRES & WILL WORK.

IF THIS IS NOT DONE IT WILL DAMAGE THE IGNITION MODULE OR COIL.

COIL HOOKUP GUIDELINES
1. Use only resistor plugs & resistor plug wires even when grounding outputs on two output coils for single output use.
2. Do not touch the green or brown output wires to +12 VDC.
3. A total of 2.8 ohms is the minimum allowable coil resistance.
4. Do not hook up coils with power (12 VDC) applied to the coils & ignition module.
5. Be sure the coil used does not require a ballast resistor, if it does, it must be used.
6. Make sure not to run wiring near high heat areas of the motorcycle, as the exhaust system.
7. Use only new or known to be good coils.
