PRESTART CHECKLIST

• The only wires connected to the new coil terminals should be
the orange connected to coil positive (+) and black connected
to coil negative (–).
• Power leads are connected directly to the battery positive and
negative terminals.
• Both coil wires are seated into place.
• The engine is equipped with at least one ground strap to the
chassis.
TROUBLESHOOTING
This section offers several tests and checks you can perform to
ensure proper installation and operation of the HYFIRE
Ignition Control. If you experience a problem with your HYFIRE
6EZ, first check for proper installation and poor connections.
You can eliminate many problems by checking these items. If
you have any questions concerning your HYFIRE
Control contact the Mallory Technical Service Department at
216.688.8300, Monday through Friday, 8:30 am to 5:30 pm
Eastern time.
Misses and Intermittent Problems
Experience has shown that if your engine is misfiring or hesitating
at higher RPM, it is usually not an ignition problem. Most common
causes include a coil or plug wire failure, arcing from the cap or
boot plug to ground or spark ionization inside the cap. Perform the
following checks:

• Inspect the plug wires at the cap and at the spark plug for a
tight connection. Visually inspect for cuts, abrasions, or burns.
The higher energy of the new ignition can create an arching
problem if the spark plug wires have deteriorated. This will
make the engine miss.
• Inspect the primary coil wire connections. Because the
HYFIRE
from the battery, there will not be any voltage at the coil
positive (+) terminal, even with the key turned on. During
® 6EZ
cranking, or while the engine is running, very high voltage
®
will be present and no test equipment should be connected.
WARNING: Do not touch the coil terminals during cranking or
while the engine is running.
® 6EZ Ignition
• Make sure that the battery is fully charged and the connec-
tions are clean and tight. If you are not running an alternator,
this is an imperative check. If the battery voltage drops below
10 volts during a race, the HYFIRE
voltage will drop.
• Is the engine running lean? Inspect the spark plugs and the
entire fuel system.
• Check all wiring connections for corrosion or damage.
Remember to use proper connections followed by soldering,
then seal the connections completely.
