GENERAL INFORMATION
The features of the HYFIRE
®
6EZ and HYFIRE
®
6EZ RPML are
the same, with one exception: the HYFIRE
®
6EZ RPML includes
a single stage RPM limiter. You can set various RPM limits using
switches that are accessible through the rectangular cut-out in
the end bracket. See page 4 of this instruction form for more
information about the rev limiting features of the HYFIRE
®
6EZ RPML.
Battery
The HYFIRE
®
6EZ Series Ignition Control operates on any negative
ground, 12 volt electrical system with a distributor. It will also
work with 16 volt batteries and can withstand a momentary spike
of 24 volts in case of jump starts. This system delivers full voltage
with a supply of 10-18 volts, and operates with a supply voltage
as low as 8 volts. If your application does not use an alternator,
allow at least 15 amp/hour for every half hour of operation. If you
crank the engine with the same battery or other accessories, such
as an electric fuel or water pump, increase the amp/hour rating.
Coils
The ProMaster
®
e
Performance Coil will deliver optimum
performance with your HYFIRE
®
6EZ Ignition Control. The stock
coil on the vehicle is also retained.
Spark Plugs and Wires
High quality, spiral wound wire and proper routing are essential
to the operation of the HYFIRE
®
6EZ Ignition Control. This type of
wire provides a good path for the spark to follow while minimizing
electromagnetic interference (EMI).
NOTE: Do not use solid core spark plug wires with the
HYFIRE
®
6EZ Ignition Control.
Routing
Wires should be routed away from sharp edges, moving objects,
and heat sources. Wires that are next to each other in the
engine’s firing order should be separated. For example, in a Chevy
V8 with a firing order of 1-8-4-3-6-5-7-2, the #5 and #7 cylinders
are positioned next to each other on the engine as well as in the
firing order. Voltage from the #5 wire could jump to the #7 wire.
This could cause detonation and engine damage. For added
protection against cross-fire, Mallory offers PRO SHIELD insulated
sleeving. Pro Shield is a glass woven, silicone coated protective
sleeve that slides over your plug wires. It also helps reduce
damage from heat and sharp objects.
MISCELLANEOUS INFORMATION
Sealing
Do not attempt to seal the HYFIRE
®
6EZ Ignition Control. All of the
circuits of a HYFIRE
®
6EZ receive a conformal coating of sealant
that protects the electronics from moisture. Sealing the HYFIRE
®
6EZ will not allow any moisture that seeps in through the
grommets to drain and may result in corrosion.
NOTE: Do not install the HYFIRE
®
6EZ Ignition Control in any
vehicle that is originally equipped with a CD ignition control.

Welding
To avoid any damage to the HYFIRE
®
6EZ Ignition Control when
welding on the vehicle, disconnect the positive (red) and negative
(black) power cables of the HYFIRE
®
6EZ Ignition Control. It is also
a good idea to disconnect the tachometer ground wire
as well.
Distributor Cap and Rotor
We recommend installing a new distributor cap and rotor when
installing the HYFIRE
®
6EZ Ignition Control. Be sure the cap is
clean inside and out, especially the terminals and rotor tip. On
vehicles with smaller caps, it is possible for the air inside the cap
to become electrically charged causing crossfire which can result
in misfire. You can prevent this by drilling a couple of vent holes
in the cap. Drill the holes between terminals at rotor height, facing
away from the intake. If needed, place a small piece of screen
over the holes to act as a filter.
Hyfire
®
6EZ Diagnostic LED (Not available with rev limiting
ignition 6EZ RPML). On the end panel of your Hyfire 6EZ ignition
there is a small hole. Behind this hole is a red LED indicator.
The LED will flash when receiving a proper trigger signal from
the vehicle. If, after a normal power-up, the LED doesn’t flash
when cranking the engine, you should check your triggering
circuit for problems. If the LED flashes
when the engine is cranked, but there
is still no spark, the problem lies
somewhere else.
Hyfire
®
6EZ Cylinder Selection
Your HYFIRE
®
6EZ Ignition comes from
the factory set up for 8 cylinder
operation. If you want to use this
ignition with a 4 or 6 cylinder engine,
you must first remove the four screws
that hold the endplate with the LED hole. Once
the endplate is removed, you’ll see the end of the
circuit board. Look for the two-section switch. To select
4 cylinder mode, move the switch marked "1" to the "ON"
position. To select 6 cylinder mode, move the switch marked "2"
to the "ON" position. If both switches are "OFF", or both are
"ON", the ignition will run in the 8 cylinder mode. See Figure 1.

MOUNTING
The HYFIRE
®
6EZ Ignition Control can be mounted in any
position. If you mount it in the engine compartment, keep it
away from moving objects and heat sources. Do not mount
the unit in a closed area, such as the glovebox. When you find
a suitable location to mount the unit, make sure all wires of the
ignition reach their connections. Hold the ignition in place and
mark the location of the mounting holes. Use a 1/8" drill bit to drill
the holes. Use the supplied self-tapping screws to mount the box.
The ProMaster
®
e
Performance Coil can be mounted in any
position. We recommend placing it within 24" of the distributor
for ease of wiring.

The two heavy gauge wires (14 gauge) that deliver battery voltage
to the ignition:
Heavy Red
Connects directly to the battery positive (+)
terminal or to a positive battery junction. It
could also be connected to the positive side of
the starter solenoid.
NOTE: Never connect this
wire to the alternator.
Heavy Black
Connects directly to the battery negative (-)
Orange/Black
Plugs into the coil connector. These are the
Connector
only wires that make electrical contact with the
ProMaster
®
e
Performance Coil.
ROUTING WIRES
Route all wires away from heat sources, sharp edges, and moving
objects. Route the trigger wires separate from the other wires and
spark plug wires. If possible, route them along a ground plane,
such as the block or firewall, which creates an electrical shield.
The magnetic pickup wires should be routed separately and
twisted together to help reduce extraneous interference.
WARNING: The HYFIRE
®
6EZ Ignition Control is a capacitive
discharge ignition. High voltage is present at the coil primary
terminals. Do not touch these terminals or connect test
equipment to them.

TROUBLESHOOTING
This section offers several tests and checks you can perform to
ensure proper installation and operation of the HYFIRE
®
6EZ
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
®
6EZ Ignition
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
®
6EZ Ignition Control receives a direct 12 volt source
from the battery, there will not be any voltage at the coil
positive (+) terminal, even with the key turned on. During
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.
• 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
®
6EZ Ignition Control output
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.

INFORMACIÓN GENERAL
Las características del HYFIRE
®
6EZ y el HYFIRE
®
6EZ RPML son
idénticas, excepto que el HYFIRE
®
6EZ RPML incluye un circuito
limitador de RPM de una fase.
Se pueden establecer varios límites de RPM usando interruptores
que se acceden mediante la sección rectangular recortada en el
soporte terminal. Vea la página 4 de estas instrucciones para
obtener información adicional sobre las características de
limitación de revoluciones del HYFIRE
®
6EZ RPML.
Batería
El control de arranque serie HYFIRE
®
6EZ funciona en cualquier
sistema eléctrico de 12 voltios con tierra negativa que tenga
distribuidor. También funciona con baterías de 16 voltios y puede
soportar picos momentáneos de 24 voltios en caso de arranques
con conexión en puente provisional. Este sistema proporciona el
voltaje completo con suministro de 10 a 18 voltios y funciona con
un voltaje de suministro de hasta 8 voltios. Si su aplicación no
utiliza alternador, debe dejar por lo menos 15 amperios/hora por
cada media hora de funcionamiento. Si el motor gira con la
misma batería u otros accesorios, tales como una bomba
eléctrica de combustible o agua, aumente la capacidad de
amperios/hora.
Bobinas
La bobina ProMaster
®
Performance
e
Coil™ proporcionará el
rendimiento óptimo con el control de arranque HYFIRE
®
6EZ.
También se mantiene la bobina original del vehículo.
Bujías y cables
Los cables de alta calidad y bobinados en espiral, y el cableado
apropiado son fundamentales para el funcionamiento del control
de arranque HYFIRE
®
6EZ. Este tipo de cable proporciona una
buena ruta para la chispa y al mismo tiempo minimiza la
interferencia electromagnética (EMI, por sus siglas en ingles).
NOTA: No utilice cables para bujías con núcleos sólidos con
el control de arranque HYFIRE
®
6EZ.
Cableado
Los cables se deben colocar lejos de los bordes cortantes,
objetos en movimiento y fuentes de calor. Se deben separar los
cables que son consecutivos en el orden de encendido del motor.
Por ejemplo, en los motores Chevy V8 con orden de encendido
1-8-4-3-6-5-7-2, los cilindros 5 y 7 están ubicados uno al lado
del otro en el motor y en el orden de encendido. El voltaje
del cable 5 podría saltar al cable 7. Esto podría ocasionar
detonaciones y averías en el motor. Para obtener protección
adicional contra la interferencia, Mallory ofrece el forro aislado
PRO SHIELD. Pro Shield es un forro protector de tejido de vidrio y
revestido de silicón que se desliza sobre los cables de las bujías.
También ayuda a reducir los daños producidos por el calor y los
objetos cortantes.
INFORMACIÓN MISCELÁNEA
Sellado
No intente sellar el control de arranque HYFIRE
®
6EZ. Todos los
