spark plugs. 3) Drilling or cutting of any kind into the module 4)
Incorrect wiring of the module. 5) Use of module on systems with
defective charging systems. 6) Use of defective or incorrect coils
7) Directly shorting the coil output wires to +12 VDC. 8) Physical

LIMITED WARRANTY
Power Arc Ignition Co., Inc. warrants to the original retail
purchaser of a Power Arc IDS ignition that it will, free of charge,
repair or replace at its own option, the product if returned to
Power Arc Ignition Co., Inc. within 6 months after purchase and if
found by Power Arc Ignition Co., Inc. to be defective in material or
workmanship. This warranty is not transferable by the purchaser
and shall be voided: if alterations not authorized by Power Arc
Ignition Co., Inc. are made in the equipment or if the serial
number or date of manufacture has been altered, defaced or
removed. Nor does this warranty apply: if the equipment has
been subjected to accident, misuse, improper hookup, damaged
by flood, fire, or act of God, or has been used on circuits or
voltages other than those indicated in its instruction manual. If
the equipment is found to be defective in materials or
workmanship the equipment will be returned and Power Arc
Ignition Co., Inc. will pay the return shipping (this does not include
next day shipping, second day shipping, shipments outside of the
continental U. S. A. or shipments outside of the U.S.A.). All
warranty work outside of the U.S.A. must include prepayment of
return shipping. Customs, duties or tariffs are not covered by this
warranty. If the equipment is found to be defective but is due to
customer misuse (as described in warranty) Power Arc Ignition
Co., Inc. will notify the customer and if the customer wants the
defective equipment returned Power Arc Ignition Co., Inc. will
return the equipment C.O.D. freight. If the equipment is found to
be in operational order when returned to the factory Power Arc
Ignition Co., Inc. will return the module with a $30.00 service
charge plus freight and C.O.D. Charges. Any module returned
under the warranty must include note of explanation of failure and
be accompanied by a dated bill of sale. Power Arc Ignition Co.,
Inc. warranty obligations are limited to those set forth herein and
no other obligations, expressed or implied, are assumed by
Power Arc Ignitions Co., Inc. Some states do not allow the
exclusions or limitations of incidental or consequential damages,
or allow limitations on how long an implied warranty lasts, so the
above limitations or exclusions may no apply to you. This
warranty gives you specific legal rights, and you may also have
other rights which vary from state to state.
SPARK PLUG WIRES
Choice of spark plug wires is an important consideration when
using an electronic ignition system. Use ONLY Resistor
(CARBON CORE) or Approved Spiral Wound Spark Plug
Wires& Resistor Spark Plugs. Solid or Spiral unapproved
spiral wound wires will damage the ignition module and
void the warranty!
SPARK PLUGS
You must use a resistor spark plug with electronic ignitions.
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:
Spark plug Multi-Spark 0.025-0.032
The higher the engine compression, the
more voltage required to fire the plug, and the narrower the plug
gap should be.
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.
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.
Many things effect spark plug gap settings:
Multi-Spark:
Compression Ratio:
RPM:
Encoder (rotor) Installation and Cam end play
Cam end play should not exceed 0.020”. The encoder disk
should be fall the constraints of the optical pickup triggers.

WARNING: Do not touch coil output wires Orange or White to
+12. DO NOT use Solid or Spiral wound suppression spark plug
wires of less than 800 Ωper foot. DO NOT bundle module
control wires with HV spark plug wires. DO NOT use with
lithium ion batteries. Failure to observe these precautions will
damage Ignition & Void the Warranty.
1. Turn the ignition/kill switch OFF. Remove and replace the existing
ignition coil with a Power Arc Coil MC-1 or appropriate coil.
2. Remove all components from the ignition cam cover (points plate
and flyweights), exposing the cam shaft end.
3. Insert ignition in place of the original points plate, with wires in
best position to exit. Insert the Ignition hold down standoffs &
tighten.
4. Connect Red wire of module to switched (+) Positive from
ignition/kill Switch. Connect the coil + terminal post to the (+)
Positive battery terminal via a fuse placed close to the battery
positive terminal.
5. Attach the Blue & Brown wires to (-) Negative for normal stock
operation.
6. Hook the green wire to the tachometer trigger wire if used, if not
used Isolate.
7. Insert the encoder adapter through the center hole of the ignition .
Rest the optical encoder wheel centered on the Encoder Standoff.
Place the stainless shim washer on to the step washer, push
through the center of the Encoder Disk into the Encoder Standoff.
Using the existing flyweight screw or bolt apply pink 222MS Loctite
to the screw and insert the hex head screw through the center of the
adapter and lightly tighten (see diagram below).
8. Connect Black (-) Negative wire of module to the Frame or the
battery Negative.
9. Rotate the engine to TOP DEAD CENTER of either cylinder. If
your engine does not have a cylinder Top Dead Center timing mark,
it may be necessary to use a piston stop, dial indicator, degree
wheel, or other appropriate method. Make a mark on crank to crank
case for later reference.
10. Put transmission in neutral, then power on to the ignition
module. Rotate the optical encoder in the opposite direction of cam
rotation until the static timing LED lights and stop. Holding the
optical encoder to prevent it from moving, tighten the adapter bolt. If
encoder rotates when tightening causing LED to go out, fine tune by
loosening module screws and rotating the module. Recheck top
dead center to make sure the timing has not moved.
11. Connect the Orange Coil Trigger to (TRIG) of the coil.
White wire is not used on a twin cylinder engine.
12. Replace the spark plug wires.
13. Turn the ignition/kill switch ON and start the engine.
