COMMON QUESTIONS AND ANSWERS
(The Lobe Sensor Ignitor II does not use a magnet sleeve)
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

12-VOLT NEGATIVE GROUND INSTRUCTIONS
1 PRIOR TO INSTALLATION TURN IGNITION SWITCH OFF OR DISCONNECT THE
BATTERY.
2 Remove distributor cap and rotor from distributor. Do not disconnect the spark plug
wires from the cap. Examine parts for excessive wear. Replace as needed.
3 Disconnect the point wire from the negative (-) side of the coil.
4 Remove and retain the point wire, point and condenser. Installing the Ignitor does
not alter the internal configuration of your 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.
6 Install Ignitor II onto breaker plate:
• PART NUMBER 91168LS & 2163LS,
Position the Ignitor plate over the point pivot
pin and eccentric adjustment screw, rotate eccentric screw as needed to line up
screw hole to breaker plate. Confirm that the Ignitor plate is flat and fits without
modifications. Fasten the plate into place using the original point screw.
• No air gap adjustment required.
• PART NUMBERS: 9LU-146LS, The condenser may be
soldered to the breaker plate on some distributors. Flex
the condenser back and forth to remove the condenser.
Position the Ignitor plate over point pivot pin and line
up hole on adapter plate to screw hole on the breaker
plate. See figure 2.
Confirm that the Ignitor plate is flat
and fits without modifications. Fasten the plate into
place using the original point screw.

3. The Lobe sensor Ignitor II is designed specifically for the application and distributor
numbers that are listed in the application guide. Any modification to this component
will void the warranty.
4. The Lobe Sensor Ignitor II does not require a magnet sleeve to trigger the module.
5. The Ignitor II ignition can be used in conjunction with most ignition coils rated at
0.45 ohms or greater.
6. All external resistors must be removed to achieve optimum performance from the
Ignitor II ignition system.
7. The Ignitor II is compatible as a trigger for most electronic boxes.
