12-VOLT NEGATIVE GROUND 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.
Q. How can I receive additional help?
A. Check our web site for current trouble shooting tips and up to date technical
information. Log on to www.pertronix.com. You may also contact our tech line at

FOR PART NUMBERS:
9ML-162, 9ML-186A & 9ML-182
GENERAL INFORMATION
1. IMPORTANT: Read all instructions before starting installation.
2. DO NOT USE WITH SOLID CORE SPARK PLUG WIRES.
3. The Ignitor II ignition can be used in conjunction with most ignition coils rated at
0.45 ohms or greater.
4. All external resistors must be removed to achieve optimum performance from the
Ignitor II ignition system.
5. The Ignitor II is compatible as a trigger for most electronic boxes.
9ML-162 & 9ML-186A DISTRIBUTOR DISASSEMBLY
1. PRIOR TO INSTALLATION TURN IGNITION SWITCH OFF OR DISCONNECT
THE BATTERY
2. Remove the distributor cap, and rotor. Do not disconnect spark plug wires.
Examine cap and rotor for wear or damage. Replace as needed.
3. Disconnect the point wire from the negative (-) terminal of the coil.
4. Remove the point wire, points, and condenser from the distributor.
5. The Ignitor does not require any modification to the distributor. Therefore the
point, condenser and hardware can be used as backup.
6. Clean all dirt and excess oil from the breaker plate and point cam.
IGNITOR II INSTALLATION
1. Remove the Ignitor II module from the adapter plate, place the Ignitor adapter
plate over the point pivot, align adapter plate to screw hole on breaker plate. See
figure 1. Use the provided screw to hold the plate in place.
2. Install the Ignitor II module onto the adapter plate. Use the provided nuts and
washers to fasten the module in place. Do not overtighten.
3. Place the magnet sleeve over the distributor shaft, and onto point cam. Press
down firmly to insure magnet sleeve is fully seated.
4. Place spacer ring onto the bottom of the rotor.
5. Install the rotor and spacer ring onto the shaft. The rotor will only fit one way.
Press the rotor down firmly.
6. Air gap between module and magnet
sleeve is not adjustable.
7. Place the grommet into the hole in the
distributor housing. Pull the excess wire
out and insure wires do not interfere with
moving parts.
8. Re-install the rotor and cap. Make sure all
spark plug wires are securely attached.
Warning!
DO NOT USE WITH SOLID
CORE SPARK PLUG WIRES.
9. See wiring Instructions.
