IGNITOR INSTALLATION

NOTE: 9HO-181 IS FOR CLOCKWISE ROTATING DISTRIBUTORS AND 9HO-183 IS 1.
FOR COUNTER CLOCKWISE ROTATING DISTRIBUTORS.

Remove distributor cap and rotor from distributor. Do not disconnect spark plug wires 2.
from cap. Examine cap and rotor for wear or damage. Replace as needed.
Remove brown and red wire from Ignition coil. 3.
Disconnect and remove the original sensor and external igniton module. 4.
Clean all dirt and excess oil from the breaker plate and reluctor.5.
Install the Ignitor II adapter plate into the distributor. Fasten the plate into place using the 6.
provided screw.
Install module over studs and down onto the adapter plate. Use the provided nuts and 7.
lock washers to secure the module in place.
Mount sleeve over distributor shaft, onto reluctor. Rotate the sleeve until a slight locating 8.
position is felt before applying pressure. Press down firmly insuring sleeve is fully seated.

Insert wires through hole in the distributor housing and pull wire grommet into place. 9.

CAUTION: Care must be taken to insure wires do not interfere with moving parts.

Re-install rotor and distributor cap. Make sure all spark plug wires are securely attached. 10.

See wiring Instructions.11.

COMMON QUESTIONS AND ANSWERS

The Ignitor II ignition can be used in conjunction with most ignition coils rated at 0.45 1.

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 Ignitor II wire to 2.

the positive coil terminal. (See Figure 1)

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 connected

to the positive coil terminal, back to the fuse

block. Bypass this wire with a 12-gauge

copper stranded wire.

(WITHOUT EXTERNAL RESISTOR)

FIGURE 1

B. Alternative Installation: The Ignitor II can also

be installed in applications retaining the ballast resistor or resistance wire.

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. 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. 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 star t 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. The Ignitor II is compatible with coils having a

resistance of 0.6 ohms or greater.

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.

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.

Check to insure that the polarity is correct, and that all connections are tight.3.

Re-connect the battery.4.

Start the engine and allow it to reach normal operating temperature. Check ignition 5.

timing, and adjust to the desired setting.

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.
