PerTronix Ignitor II 91247XT - Manual (Page 2)

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.

DISTRIBUTOR INSTALLATION.
1. Install the rotor.
2. Turn the rotor to the position that was noted prior to the removal of the
distributor.
3. Place distributor into block and fasten in place with the original mounting
bolts. Note: Do not force the distributor onto place. Check to make sure
that dive tang is properly aligned.
WIRING.
1. Feed the black and red Ignitor wire through the opening where the coil
was previously.
2. Insert the wires through the hole in the coil block off plate. Pull the grom-
met into place.
3. Install the provided distributor cap. This cap has been modified to accept a
screw in terminal.
4. Place the coil block off plate into possition. Use the provided screw and
washer to mount the plate to the distributor body.
5. Place the two shim washers and the plastic spacer onto the threaded
terminal and screw it into the distributor cap.
6. Attach the red Ignitor II wire to the positive coil terminal. (See Illustration
C.)
7. Attach the Ingition switch wire to the coil positve terminal.
8. Attach the black Ignitor II wire to the coil negative terminal. ( See Illustra-
tion C.)
9. Install the provided coil plug wire. W arning! DO NOT USE SOLID CORE
SPARK PLUG WIRES.
3. Static timing the distributor by positioning the plate so the the slide is
positioned in the middle of the adjustment slot. The adjustment nut should
be centered with the cap spring clip (See illustration B). Tighten the nut
once it is aligned properly.
4. Install the plate retaining ring. The flat portion of the ring should be placed
on the adjustment slot side of the distributor.
5. Install the Ignitor II module onto the mounting studs.
6. Tighten the module into place with the hardware provided.
7. Install the magnet sleeve onto the point cam.
8. Install the shim washer onto the distributor shaft.
9. Install the shaft support bracket. Spin the distributor shaft to align the
bracket and tighten in place with the 8-32 screws provided.
