PerTronix Ignitor II 92842 - 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), 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.
B. Alternative Installation: The Ignitor II can also be installed in applications retaining
the ballast resistor or resistance wire.
• 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 operat-
ing temperature. Check
ignition timing, and adjust
to the desired setting.

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
• Part number 91843:
•
Remove module from adapter plate before proceeding. Install Ignitor II
adapter plate using the same screw holes the points used. Be sure Ignitor
plate is lying flat. Secure the Ignitor plate using the screw provided.
• Place the Ignitor II module on the adapter plate studs. Secure module
with the lock washers, 8-32 nut and allen screw provided.
• Install magnet sleeve over distributor shaft, onto point cam. Rotate sleeve
until a slight locating position is felt before applying pressure. With mag-
net sleeve lined up on point cam, press down firmly insuring sleeve is
fully seated.
• Part Numbers 91863 & 91867A:
•
Remove module from adapter plate before proceeding. Install Ignitor II
adapter plate using the same screw holes the points used. Be sure Ignitor
plate is lying flat. Secure the Ignitor plate using the screw provided.
• Place the Ignitor module on the adapter plate studs. Secure module with
the lock washers and small patter 8-32 nuts provided. DO NOT TIGHTEN
NUTS COMPLETELY AT THIS TIME.
• Use the plastic feeler gauge provided to set the air gap between the
module and the magnet sleeve. Note: If the plastic feeler gauge is not
provided, use a regular feeler gauge to set air gap, the air gap can be set
anywhere between 0.010” to 0.050”. Once the proper air gap is achieved
tighten module securely to adapter plate.
• Install magnet sleeve over distributor shaft, onto point cam. Rotate sleeve
until a slight locating position is felt before applying pressure. With mag-
net sleeve lined up on point cam, press down firmly insuring sleeve is
fully seated.
5. Note: If the original ground strap was removed (vacuum advance, retard
type distributors only), it must be re-installed to properly ground breaker
plate to distributor housing. Insert the Ignitor black and red wires into
opening in the side of the distributor housing. Verify the grommet is
seated properly.
6. Adjust wire length in the distributor through the grommet to insure ample
clearance. Make sure all wires are clear of moving parts.
7. Reinstall rotor and distributor cap. Make sure all spark plug wires are
securely attached. Warning! DO NOT USE WITH SOLID CORE SPARK
PLUG WIRES.
8. See wiring instructions.
