Mallory Ignition Mallory MAX-FIRE AND E-FIRE ELECTRONIC DISTRIBUTORS - Manual (Page 2)

OLD DISTRIBUTOR REMOVAL
Step 1
Disconnect the trigger wire from the coil
negative (-) terminal.
Step 2
Locate the spark plug wire on the original
distributor cap that the engine timing is set
from. See a service manual for these locations.
Mark the distributor cap and the distributor
housing, in line with this spark plug wire position
on the distributor cap.
Step 3
Turn the engine crankshaft in the direction of
rotation until the timing mark lines up with the
top dead center (TDC) mark on the timing tab.
See a service manual for these locations.
NOTE: Removing the spark plugs may make it
easier to turn the crankshaft.
Step 4
Remove the distributor cap from the distributor.
Do not remove the spark plug wires or coil wire
at this time. The rotor blade should point to the
mark made on the distributor housing (from
Step 2). If it is not, turn the engine crankshaft in
the direction of rotation one full turn (repeating
Step 3) until the timing mark lines up (again)
with the TDC mark on the timing tab.
NOTE: Once you are finished with Step 4,
DO NOT turn the crankshaft until the new
distributor is installed.
Step 5
Note the direction the rotor is pointing. Remove
the distributor hold down clamp and remove the
distributor from the engine.
DISTRIBUTOR INSTALLATION
Step 1
Prepare the distributor by removing the
distributor cap.
Step 2
Place the distributor in the engine with the rotor
pointing in the same general direction as the
original distributor.
NOTE: The distributor must be fully seated into
the engine. It may be necessary to turn the oil
pump drive, or turn the engine crankshaft in the
direction of rotation two full turns until the timing
mark lines up (again) with the TDC mark on the
timing tab, to allow the distributor to seat fully.

Step 3
Rotate the distributor housing in the
opposite direction of rotor rotation until the leading
edge of the blade portion of the trigger wheel is
centered in the Hall sensor pickup gap. This will
generally put timing close enough for starting
purposes. Put the distributor hold down clamp
in place and tighten slightly, leaving it loose
enough to turn the distributor. Make a mark on
the distributor housing where the rotor points.
Step 4
Install the distributor cap. Remove the spark
plug wire on the original distributor cap that the
engine timing is set from, and install it onto the
distributor cap post above the mark on the
distributor housing where the rotor had pointed.
Continue installing each remaining spark plug
wire, one at a time, from the original distributor
cap to the distributor cap in the same sequence.
NOTE: It may be necessary to purchase and
install distributor boots and terminals for the
spark plug wires to correctly fit the distributor cap.
DISTRIBUTOR WIRING
There are three harnesses coming from the
distributor body:
4-PIN SQUARE CONNECTOR – this is the
data connector for the PC or external handheld
programmer. It is only used when adjusting the
distributor with an external controller or PC.
3 PIN FLAT CONNECTOR – this is the power
connector.
BLACK WIRE- connects to the vehicle ground
(engine block). Make sure the surface is free of
dirt, grease and paint.
RED WIRE- connects to the 12 volt ignition
wire from the key switch (there should not be
any ballast resistors or loom resistance wire in
this wire). Refer to a service manual’s wiring
diagram to determine the correct wire. Make
sure the wire supplies 12 volts when the switch
is in the start position and the run position.
WHITE WIRE- this wire is NOT USED with the
22 Series E-Fire inductive storage distributor. It
is used as a 12v square wave tach output with
the 12 Series MAX-Fire. Verify the series you have
by the first 2 digits of the distributor part number.
2 PIN FLAT CONNECTOR–this is the coil connector
ORANGE WIRE-connects to the coil + terminal
BLACK WIRE-connects to the coil – terminal
