IMPORTANT: Before starting the installation of the UNILITE ® Ignition System, make sure that the 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. You can test your stock ignition system voltage while the
engine is at idle at the coil (+) terminal. If the measured voltage is within 1 volt of battery voltage, an ignition ballast resistor must be
installed in the wire from the ignition switch. 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. Failure to use an ignition ballast resistor will result in the
eventual destruction of the UNILITE ® Ignition Module. Exception: If your vehicle is equipped with a HYFIRE ® Electronic Ignition Control or
similar aftermarket ignition control, use ignition ballast resistors and wiring procedures as stated in the instructions for the particular
ignition control.
GENERAL INFORMATION
IGNITION COILS
The UNILITE ® Ignition System is designed to work with most stock ignition coils
and aftermarket high performance ignition coils. For optimum performance,
use a Mallory PROMASTER ® Coil Part No. 29440 or 29625, or Mallory
Chrome Electronic Ignition Coil Part No. 29216.
SPARK PLUG WIRES
To prevent false triggering and the possibility of premature ignition failures, use
suppression-type spark plug wire. We recommend spiral core ignition wire,
such as Mallory PRO SIDEWINDER ® Ignition Wire.
SPARK PLUG GAPS
For street applications, use your engine manufacturer’s specifications. For
racing applications, start with your engine manufacturer’s specifications, then
experiment with and closely monitor various gaps to achieve maximum
performance.
ELECTRIC WIRING
Unplug the distributor wire harness before welding on the vehicle.
OPTIONAL ACTIVE POWER FILTER PART NO. 29351
Voltage spikes (voltage transients, power surges) are associated with “noisy”
electrical systems from electrical defects such as worn alternator brushes,
corroded or oxidized electrical connections and similar electrical problems.
This device protects the UNILITE ® Ignition Module against voltage spikes.
