WIRING INSTRUCTIONS
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.
1. Use the provided ring terminals to attach each of the black Ignitor wires to the
negative (-) terminal of each coil.
2. Attach each of the red Ignitor wires to the positive (+) terminal of each coil.
3. The module wires that exit the distributor at the “A” location should be attached to
the “A” coil and the module that exit the “B” location should be connected to the
“B” coil.
4. Check and insure that the polarity is correct, and that all connections are tight.
5. Reconnect battery and make sure all wires are connected.
6. The engine can now be started. Let the engine run for a few minutes and then set
the Ignition timing in the conventional manner.
7. Install snap ring, bearing and bearing support.
8. Install the rotor by aligning the dots on the shaft and rotor.
9. Install the distributor cap. Make sure all spark plug wires are securely attached.
Warning!
DO NOT USE WITH SOLID CORE SPARK PLUG WIRES.
10. See Wiring Instructions.
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 starts 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.
