PerTronix Ignitor II 91164 - Manual (Page 2)

WIRING INSTRUCTIONS
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), dis-
connect 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 con-
nected to the positive coil terminal, back to the fuse block. Bypass this wire with a
12-gauge copper stranded wire.
The Ignitor II ignition can be used in conjunction with most ignition coils rated at 0.45
ohms or greater. For optimum performance purchase and install the Flamethrower II
high performance coil. See back page for coil recommendations.
• DO NOT USE SOLID CORE SPARK PLUG WIRES.
1. Attach the black Ignitor II wire to the negative (-) coil terminal. (See Figure 3)
2. Attach the red Ignitor II wire to the positive (+) coil terminal. (See Figure 3)
3. Check to insure that the polarity is correct, and that all connections are tight.
4. Re-connect the battery.
5. Start the engine and allow it to reach normal operating temperature. Check igni-
tion timing, and adjust to the desired setting.

not tighten these kep nuts at this time.
13. Install Ignitor module in the same holes where the points were. NOTE:
Dual point distributors require the module to be mounted in the place
of the leading point. Use the screws that held the point assembly to the
breaker plate. Screws should be finger tight at this point.
Caution - BE sure that magnet ring is seated against the advance mechanism
plate and the module is seated against breaker plate. The shaft must be
seated in the lowest position when measuring gap.
14. You will be trying to get an air gap between approximately 0.010” at the
low end and no more than 0.060” at the high end. With the distributor
shaft pulled down, rotate the shaft and make sure the magnet ring does
not rub against the Ignitor module. If it happens to rub against the Ignitor
module, carefully bend the Ignitor module bracket down until it does not
rub. Bend with pliers at the bracket so as not to loosen the rivets. If there
is a gap, rotate the distributor shaft and measure the largest air gap
between the face of the magnet ring and the face of the Ignitor module. If
you have an Oldsmobile, and the largest gap is more than 0.060”, go to
step #14. Otherwise, continue with the next step.
15. If the gap is greater than 0.060” record what it is. The gap is adjusted by
installing thin washers over the 6/32 studs between the magnet ring and
advance mechanism plate. It is necessary to remove module, rotor, and
ring to do this. The washers are 0.032” thick. From the gap measurement
recorded, Calculate how many washers are needed to bring the lowest
part of the magnet ring to approximately 0.010” from the Ignitor module.
Install washers on each side. if you have an Oldsmobile, go to step #14.
Otherwise, go to the next step.
16. Now push the distributor shaft up and rotate. If the highest point between
the Ignitor module and the ring is greater than 0.060”, you will need to
place shims between the gear and distributor housing to prevent the gap
from going over 0.060”.
17. Reinstall magnet ring, rotor and module. Secure in position. Double check
gap. If readjustment is necessary, follow the above procedure.
18. Instal the rubber grommet from the kits hardware into the large hole on
the bottom of the distributor housing.
19. Place both the red and black wires carefully through the grommet.
20. Attach terminals to the ends of both wires. You may cut wires to your
desired length if they are too long.
21. Reinstall distributor in vehicle, making sure rotor is in same position as
when removed.
22. Place distributor cap on distributor. All spark plugs wires should be
seated securely.
