No-Run on Foreign Vehicles
Some foreign vehicles with fuel injection
systems may require a tachometer/fuel
injection adapter to run with the NITROUS 6
Ignition Control. Often, the same trigger
source is used to operate an ignition,
tachometer, and fuel injection. This results in
a voltage signal that is too low to trigger the
fuel injection. A tach/fuel injection adapter
will usually solve this problem.
Inoperative Tachometers
If your tachometer fails to operate with the
NITROUS 6 installed, you may need a
Mallory tach adapter. Before
purchasing a tach adapter, try connecting
your tachometer trigger wire to the yellow
wire of the NITROUS 6 Ignition Control. This
output produces a 12 volt, square wave. If
the tach still does not operate, you will need
a tach adapter. Two different tach adapters
are available:
PN 29078 - If you are using the magnetic pickup
connector (green and violet wires) to
trigger the NITROUS 6, you will need
this adapter.
PN 29074 - If your tach was triggered from the coil
negative terminal (voltage trigger) and
you are using the green wire to trigger
the NITROUS 6, you will need this adapter.
Green Wire Trigger
When using the white wire to trigger the
NITROUS 6 Ignition Control, install a switch
to the green wire and the other side to
ground. When the green wire is grounded,
the vehicle will crank but will not start.
Magnetic Pickup Trigger
When using the mag pickup to trigger the
NITROUS 6 Ignition Control, install a switch
across the magnetic pickup violet wire to
ground. When the violet wire is grounded,
the vehicle will crank but will not start.
TROUBLESHOOTING
This section offers several tests and checks
you can perform to ensure proper installation
and operation of the NITROUS 6 Ignition
Control. If you experience a problem with
your NITROUS 6, first check for proper
installation and poor connections. You can
eliminate many problems by checking these
items. If you have any questions concerning
your NITROUS 6 Ignition Control contact the
Mallory Technical Service Department at
216-688-8300, option 5.
Tach/Fuel Adapters
If your tachometer does not operate correctly,
you probably need a Mallory tach adapter.
Consult the Tachometer Compatibility List
at right for common tachometers and
compatible tach adapters.
