MAGNETIC BREAKERLESS
DISTRIBUTOR INSTALLATION
Step 1
Remove 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 en-
gine crankshaft in the direction of rotation two full turns until
the timing mark lines up (again) with the TDC-mark on the tim-
ing 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 distribu-
tor. Make a mark on the distributor housing where the rotor points.
Example (Dual Pickup), see Figure 1:
Step 4
Install the distributor cap. Remove the #1 cylinder’s spark plug wire on
the original distributor cap 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
SERIES NOS. 84 AND 32 (SINGLE PICKUP)
There is a female connector with two wires coming from the distributor:
• Connect the distributor wire harness to the female connector and
route the harness two wires to the electronic ignition control.
• ORANGE-WIRE-(MAG+): Connect to the magnetic input
(MAG+)-terminal or wire on the electronic ignition control.
• PURPLE-WIRE-(MAG–): Connect to the magnetic input (MAG–)
terminal or wire on the electronic ignition control.
SERIES NOS. 81 (DUAL PICKUP)
There are two separate female connectors with two wires coming from
the distributor:
• Connect the distributor wire harness to one female connector and
route the harness two wires to the electronic ignition control.
• ORANGE WIRE (MAG+): Connect to the magnetic input (MAG+)
terminal or wire on the electronic ignition control.
• PURPLE WIRE (MAG–): Connect to the magnetic input (MAG–)
terminal or wire on the electronic ignition control.
• Connect the other distributor wire harness to the other female
connector and route the harness two wires to the other electronic
ignition control.
• ORANGE WIRE (MAG+): Connect to the magnetic input (MAG+)
terminal or wire on the electronic ignition control.
• PURPLE WIRE (MAG–): Connect to the magnetic input (MAG–)
terminal or wire on the electronic ignition control.
NOTE: Refer to the electronic ignition control instructions for
remaining power connections.
Tachometer operation: Connect tachometer wire or wires as recom-
mended by the actual tachometer manufacturer or electronic ignition
control manufacturer.
STARTING THE ENGINE
CAUTION: Be sure all tools, wires, and miscellaneous objects
are clear of moving engine parts and extremem heat before
starting 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.
Step 2
Connect a timing light. Find an area with the best view of the timing
marks.
Step 3
Start the engine. If it fails to start, rotate the distributor in small incre-
ments (either clockwise or counterclockwise) until the engine starts.
Step 4
Set timing as recommended by the engine manufacturer, then tighten
distributor hold-down clamp. Make sure timing is still correct. If timing
has moved, repeat this procedure.
