COMMON QUESTIONS AND ANSWERS
Q. The vehicle will start, but then die. After waiting it will start again. What is wrong?
A. 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. The engine will not start or runs rough. What is the problem?
A. 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. How do I check for a “Low Voltage Problem” or determine if I am getting adequate voltage?
A. 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. 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.

Wiring Instructions
The Ignitor II ignition can be used in conjunction with most ignition coils rated 1.
at 0.6 ohms or greater. For optimum performance purchase and install the
Flamethrower II high performance coil.
Attach the black Ignitor II wire to the negative coil terminal. Attach the red
2.
Ignitor II wire to the positive coil terminal. (See Figure 2)
A. Recommended Installation: Many vehicles came equipped with ballast resistors
or resistance wires. 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
•
connected 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. (See Figure 3)
Attach the Ignitor II black wire to the negative coil terminal. Attach the Ignitor •
II red wire to the ignition side of the resistance, or any 12 volt ignition power
source.
Check to insure that the polarity is correct, and that all connections are tight. 1.
Re-connect the battery. 2.
Start the engine and allow it to reach normal operating temperature. Check 3.
ignition timing, and adjust to the desired setting.
