COMMON QUESTIONS AND ANSWERS
Q. The engine will not start or runs rough. What is the problem?
A. Perform Power and Ground Checks. Check all connections to insure that they are
tight, and in the proper location. Check all grounds; if a distributor ground wire was
removed make sure that it was reattached properly. Make sure that the red Ignitor II
wire is supplied with a full 12 volts. The Ignitor II is designed to sense high current
levels, and shut off before damage occurs. Check all wires for shorts, correct polarity
and that the ignition coil’s primary resistance level is acceptable.
Q. . The vehicle will start, but then die. After waiting it will start again. What is wrong?
A. Perform Power and Ground Checks. The Ignitor II may have a “Low Voltage Problem.”
If the voltage supplied to the red Ignitor II wire is insufficient, the system may run for a
period of time, and then shut down as the voltage drops due to engine heat. The period
may vary from minutes to hours depending on available voltage and wiring condition. To
remedy this condition refer to steps 2-4 of the wiring instructions.
Q. How do I check for a “Low Voltage Problem” or determine if I am getting adequate
voltage?
A. Perform Power and Ground Checks. Also, to quickly test for a “Low Voltage Problem”
or for adequate voltage, remove the Ignitor II red wire from the coil positive terminal.
Attach a jumper wire from the battery positive terminal to the Ignitor II red wire. Try
to start the vehicle. If the vehicle star ts with this test refer to steps 2-4 of the wiring
instructions for further information.
Q. How do I check my coil for primary resistance?
A. Remove all wires from the coil. Set the ohmmeter to the lowest scale. Attach one
lead of the meter to the positive coil terminal. Attach the other lead to the negative coil
terminal.
Q. May I modify the length of the wires?
A. Yes, you may cut the wires to any length your application requires. You may also add
lengths of wire if needed (20-gauge). Make sure that all wire splices are clean and the
connections are tight.
Q. Will the Ignitor II work with aftermarket capacitive discharge boxes?
A. Yes, the Ignitor II is compatible with most CD boxes in the same respect as points.
Use the CD box wiring instructions for point systems and treat the Ignitor II black wire
as a point wire. The Ignitor II red wire should be attached to the 12-volt power source.
Q. Will the electronic shift assist in an OMC boat work with the Ignitor II?
A. The Ignitor II will work with all OMC stern-drive applications, when our “diode fix” is
used. If you’ve purchased a kit that didn’t include the “diode fix” diagram, call our tech
line.

WIRING INSTRUCTIONS
1. The Ignitor II ignition can be used in conjunction with most ignition coils rated
at 0.45 ohms or greater. For optimum performance purchase and install the
Flamethrower II high performance coil.
2. Attach the black Ignitor II wire to the negative coil ter minal. Attach the red Ignitor II
wire to the positive coil terminal. (See Figure 3)
A. Recommended Installation: Many vehicles came equipped with ballast resistor or
resistance wire. To achieve optimum performance from the Ignitor II ignition system, we
recommend removal of these components.
• To remove a ballast resistor, (normally white ceramic blocks 3 to 4 inches long),
disconnect all wires on both ends of the ballast resistor. Remove the resistor from
the vehicle and splice the
disconnected wires together
at a single point.
• To remove a resistance wire,
trace the coil power wire,
which was previously con
nected to the positive coil
terminal, back to the fuse
block. Bypass this wire with
a 12-gauge copper stranded
wire.
B. Alternative Installation: The
Ignitor II can also be installed in
applications retaining the ballast
resistor or resistance wire.

To Ignition
-
• Attach the Ignitor II black wire to the negative coil terminal. Attach the Ignitor II red
wire to the ignition side of resistance, or any 12 volt ignition power source.
3. Check to insure that the polarity is correct, and that all connections are tight.
4. Re-connect the battery.
5. Perform the Power and Ground tests. Refer to the Power and Ground test
procedure.
6. Start the engine and allow it to reach normal operating temperature. Check igni
tion timing, and adjust to the desired setting.
POWER & GROUND TESTS
It is imperative that the power and grounds be checked as part of the installation
procedure. After installing the Ignitor module and the distributor and with the
distributor in the engine, use a digital multi-meter to measure the resistance from
the aluminum plate holding the module to battery (-), the net resistance must be
less than 0.2 ohms. (Set meter to lowest ohms setting). The net resistance is the
meter reading minus the resistance of the meter leads. If the net resistance is
greater than 0.2 ohms, the source of the faulty ground must be found and fixed.
Usually the source of the bad ground is easily found by holding one probe on an
original location and moving the second probe toward the static probe. Where the
resistance drops identifies the source.
Maximum resistance from Ignitor plate to battery negative terminal. 0.2 ohms
EXAMPLE:
Resistance from Ignitor plate to battery negative (-) terminal. 0.4 ohms
Resistance of meter leads 0.2 ohms
After subtracting meter lead resistance, your net resistance is: 0.2 ohms
VOLTAGE TEST
1. (Do not disconnect wires from Ignition coil). Place ignition switch in the “off” position.
2. Connect a jumper wire from negative (-) terminal of the coil to a good engine
ground.
3.Connect the voltmeter red lead to the positive (+) terminal of the coil and the black
lead to a good engine ground.
4.Turn the ignition switch to the “on” position and note voltage reading on the voltmeter. Quickly read the voltage and turn ignition “OFF”. Leaving ignition “ON” for an
extended period could result in permanent damage to the Ignitor.
5. SEE CHART BELOW FOR SPECIFICATIONS.
Note: Low voltage can be caused by poor connections, poor contacts in the
ignition switch, ballast resistor, and or a resistance wire in the wiring harness
(Factory Installed).
Minimum Maximum
Ignition Switch “ON” 8.0V N/A
Cranking 8.0V N/A
Engine Running N/A 16.0V
