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

2. DO NOT USE WITH SOLID CORE SPARK PLUG WIRES.
3. Some modifications to the original distributor is necessary.
4. The Ignitor II ignition can be used in conjunction with most ignition coils rated at
0.45 ohms or greater.
5. All external resistors must be removed to achieve optimum performance from the
Ignitor II ignition system.
6. The Ignitor II is compatible as a trigger for most electronic boxes.

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, point, and condenser from the distributor. The Ignitor does
not require any modification to the distributor. Therefore the point, condenser and
hardware can be used as backup.
5. Clean all dirt and excess oil from the breaker plate and point cam.
IGNITOR INSTALLATION
1. Part Number 9LU-165, See Figure 1, place Ignitor over eccentric screw, rotate
if necessary to line up holes on breaker plate. See Figure 1. Secure Ignitor with
screws provided.
2. Part numbers 9LU-143 & 9LU-144, see figure 2, Install Ignitor over point guide
pin, line up point screw hole and secure with screw provided.
3. Part number 9LU-163 & 9LU-164, Ignitor II 9LU-163 is designed for NON-
VACUUM ADVANCE disitributors and Ignitor II 9LU-164 is designed for VACUUM
ADVANCE distributors. Install Ignitor over point guide pin, line up point screw hole
and secure with screw provided.
4. All Other kits, remove module from the adapter plate, Install Ignitor adapter plate
to the breaker plate using the screws provided. NOTE: 25D and 22D distributors
will use both mounting screws, 23D distributors will use one flat head mounting
screw. Place the Ignitor module on the adapter plate studs. Secure module to
adapter plate with the nuts provided.
5. Install magnet sleeve over the distributor shaft, onto point cam. Rotate the sleeve
until a slight locating position is felt before applying pressure. Press down firmly
insuring sleeve is fully seated.
