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 distributor
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
vehicle. 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
connected 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 igni-
tion 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.
