MAGNETIC BREAKERLESS
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.
If equipped with vacuum advance, place the
distributor in the engine with the rotor and vacuum
chamber pointing in the same general direction as the
original distributor.
If the old distributor did not have a vacuum chamber,
place the distributor in the engine with the rotor
pointing in the same general direction as the original
distributor did, and point the vacuum chamber in a
direction that will allow movement for timing purposes.
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 nearest tooth of the
reluctor is pointing directly at the center of the metal pole
on the magnetic pickup. 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 distribu-
tor boots and terminals for the spark plug wires to correctly
fit the distributor cap.
WIRING PROCEDURE
Make sure that your vehicle is equipped with an
ignition ballast resistor (or loom resistance wire) in the
wire between the ignition switch and the coil (+)
terminal. One easy way to find the ignition ballast
resistor is to check the service manual for your vehi-
cle. Example: Vehicles with a Ford TFI or Delco HEI
require adding an ignition ballast resistor in the wire
from the ignition switch. If you find your vehicle is
not equipped with an ignition ballast resistor, install a
Mallory Ignition Ballast Resistor Part No. 700 in series
in the wire from the ignition switch. There are three
wires coming from the distributor that must be con-
nected using the distributor wire harness furnished
(see Figures 1 and 2).
RED WIRE: If you are using loom resistance wire, connect to the
coil (+) terminal.
If you are using a ballast resistor, connect to 12 volt
side of ballast resistor.
GREEN WIRE: Connect to the coil (-) terminal.
BROWN WIRE: Connect to engine block ground. Clean away any
grease, oil and paint from the mounting surface
before the connection is made.
NOTE: If a HYFIRE ® Electronic Ignition Control or other
aftermarket ignition control is being used, connect the
distributor according to the instructions supplied with the
ignition control.
ADDITIONAL CONNECTIONS
Vacuum advance applications: Connect original
vacuum hose to the distributor vacuum chamber. Replace
hose if cracked, damaged, or if it is not long enough. If
the previous distributor was not equipped with vacuum
advance, connect a vacuum hose to a ported vacuum
outlet on the carburetor.
Tachometer operation: Connect wire or wires as
recommended by the actual tachometer manufacturer.
STARTING ENGINE
CAUTION: Be sure all tools, wires and miscellaneous objects
are clear of moving engine parts and extreme heat before
staring the engine.
Step 1
Recheck all wires and connections to make sure they
are correct. Check and clean, or replace spark plugs.
If replacing spark plugs, use types recommended by
the engine manufacturer.
Vacuum advance applications: Disconnect the
vacuum hose to distributor vacuum chamber at the
carburetor and temporarily plug this carburetor fitting.
Step 2
Connect a timing light. Find the area with the best view
of the timing marks.
Step 3
Start the engine. If it fails to start, rotate the
distributor in small increments clockwise or
counterclockwise until engine starts. Do not exceed
more than ten degrees of distributor housing rotation
in either direction.
Step 4
Set timing as recommended by engine manufacturer,
then tighten distributor hold down clamp. Make sure
timing is still correct. If timing has moved, repeat this
procedure.
Step 5
Vacuum advance applications: Reconnect the
vacuum hose between the distributor vacuum
chamber and the carburetor.
