Ford: Install the diode inline to the wire
going to the #1 terminal.
GM: Install the diode inline to the wire
going to the #4 terminal.
GM 1973-83 with Delcotron Alternators
GM Delcotron alternators use an internal
voltage regulator. Install the diode inline on
the smallest wire exiting the alternator (see
Figure 4). It is usually a brown wire.
Most other applications: To eliminate run-on,
place a resistor in-line to the OFF-ROAD
small red wire to keep voltage from leaking
into the Ignition.
Ballast Resistor
If you have a current trigger tach (originally
connected to coil (+) positive) and use the
green wire of the Ignition Control for
triggering, you can purchase a Chrysler Dual
Ballast Resistor (1973-76 applications).
Engine Run-On
If your engine continues to run even when
the ignition is turned off, you are experiencing
engine run-on. Usually, older vehicles with
an external voltage regulator are suscep-
tible to this condition. Because the Ignition
Control receives power directly from the
battery, it does not require much current to
keep the unit energized. If you are
experiencing run-on, it is due to a small
amount of voltage going through the
charging lamp indicator and feeding the
small red wire (even if the key is turned off).
Early Ford and GM: To solve the run-on
problem, a diode is supplied with the
Ignition Control. By installing this diode
in-line of the wire that goes to the charging
indicator, the voltage is blocked from
entering the Ignition Control. Figure 4
shows the proper diode installation for
early Ford and GM vehicles.
NOTE: Diodes are used to allow voltage to
flow only one way. Make sure the diode
is installed facing the proper direction, as
shown in Figure 3.
