PerTronix Ignitor II 9ML-182 - Manual (Page 2)

WIRING INSTRUCTIONS
1. 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.
2. Attach the black Ignitor II wire to the negative coil terminal. Attach the red Ignitor II
wire to the positive coil terminal. (See Figure 3)
A. 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),
disconnect 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.
B. Alternative Installation: The
Ignitor II can also be installed in
applications retaining the ballast
resistor or resistance wire.

POWER & GROUND TESTS
It is imperative that the power and grounds be checked as part of the installation
procedure. After installing the Ignitor module and the distributor and with the
distributor in the engine, use a digital multi-meter to measure the resistance from
the aluminum plate holding the module to battery (-), the net resistance must be
less than 0.2 ohms. (Set meter to lowest ohms setting). The net resistance is the
meter reading minus the resistance of the meter leads. If the net resistance is
greater than 0.2 ohms, the source of the faulty ground must be found and fixed.
Usually the source of the bad ground is easily found by holding one probe on an
original location and moving the second probe toward the static probe. Where the
resistance drops identifies the source.
Maximum resistance from Ignitor plate to battery negative terminal. 0.2 ohms
EXAMPLE:
Resistance from Ignitor plate to battery negative (-) terminal.
0.4 ohms
Resistance of meter leads 0.2 ohms
After subtracting meter lead resistance, your net resistance is: 0.2 ohms
VOLTAGE TEST
1. (Do not disconnect wires from Ignition coil). Place ignition switch in the “off” posi-
tion.
2. Connect a jumper wire from negative (-) terminal of the coil to a good engine
ground.
3.Connect the voltmeter red lead to the positive (+) terminal of the coil and the black
lead to a good engine ground.
4.Turn the ignition switch to the “on” position and note voltage reading on the voltme-
ter. Quickly read the voltage and turn ignition “OFF”. Leaving ignition “ON” for an
extended period could result in permanent damage to the Ignitor.
5. SEE CHART BELOW FOR SPECIFICATIONS.
Note: Low voltage can be caused by poor connections, poor contacts in the
ignition switch, ballast resistor, and or a resistance wire in the wiring harness
(Factory Installed).
Minimum Maximum
Ignition Switch “ON” 8.0V N/A
Cranking 8.0V N/A
Engine Running N/A 16.0V
beginning with the correctly stamped screw hole. Line up the two screw holes
in the mounting plate with the UNILITE module screw holes. Use the provided
screws to hold the mounting plate in place, tighten mounting plate screws.
11. Install the rotor-magnet sleeve assembly onto the distributor shaft.
12. Insert wires through the hole in the distributor housing, and pull the wire grommet
into place. Make sure that the wires do not interfere with any moving part.
13. Install the distributor cap, and make sure all plug wires are attached securely.
14. See Wiring Instructions.
9ML-182 ONLY DISTRIBUTOR DISASSEMBLY
1. PRIOR TO INSTALLATION TURN IGNITION SWITCH OFF OR DISCONNECT THE
BATTERY
2. Remove distributor cap and rotor from distributor. Note: Comp 9000 distributors
require the removal of cap adapter. Do not disconnect spark plug wires from cap.
Examine parts for excessive wear. Replace as needed.
3. Disconnect the UNILITE ® wire harness from the coil.
4. Remove the two screws holding the UNILITE module in place, and remove module.
5. Clean all grease and dirt from the breaker plate.
IGNITOR II INSTALLATION
Remove this material
for module clearance
Figure 2
Remove this material for
module clearance.
Note: Shutter wheel must be removed from rotor.
The magnet sleeve needs to be installed onto the rotor, replacing the shutter wheel.
A. The shutter wheel is glued to the rotor, flex shutter wheel to loosen the rotor from
the shutter wheel, do not twist.
B. Tip: Install Rotor and shutter wheel assembly onto the distributor shaft, once the
rotor is installed onto the distributor shaft, push down on shutter wheel until it slides
off the rotor.
6. Once the shutter wheel is removed from the rotor, Comp 9000 Distributors Only:
Install provided spacer before installing magnet sleeve onto rotor, align groove in
rotor to the magnet sleeve, slide the magnet sleeve onto the rotor, make sure the
number ML-182 is facing up. Some magnet sleeves may fit loose, glue may be
applied if necessary.
7. Note: Do not install magnet sleeve-rotor
assembly until after the ignitor is installed into
distributor.
8. Comp 9000 Distributors Only: Modify cap
adapter to clear Ignitor (See Figure 2).
9. The Ignitor can be installed in clockwise or
counter clockwise positions. Determine the
rotation of your distributor rotor and use
figure “A” or “B” to install Ignitor.
• FOR CLOCKWISE DISTRIBUTOR
ROTATION USE FIGURE “A”.
• FOR CLOCKWISE DISTRIBUTOR
ROTATION USE FIGURE “B”.
10. Fasten the Ignitor plate to the distributor
• Attach the Ignitor II black wire to the negative coil terminal. Attach the Ignitor II red
wire to the ignition side of resistance, or any 12 volt ignition power source.
3. Check to insure that the polarity is correct, and that all connections are tight.
4. Re-connect the battery.
5. Perform the Power and Ground tests. Refer to the Power and Ground test
procedure.
6. Start the engine and allow it to reach normal operating temperature. Check igni-
tion timing, and adjust to the desired setting.
