Bypass connector
The Bypass Connector (standard ignition
bypass) fits into the mating plug of the
Ignition Control Harness to convert back to
standard ignition. This will allow the vehicle
to run on the standard ignition and bypasses
your Nitrous 6 ignition. If you use the
Bypass Connector, use ignition
ballast resistors designed for the particular
distributor and coil in the wire from the
ignition switch. Use the Power Plug to
convert back to standard ignition. Also,
if you are using a Mallory Fuel
Injection/Tachometer Adapter (Part No.
29074), disconnect it (and its diode if used)
as part of converting back to standard
ignition. The Bypass Connector (standard
ignition bypass method to convert back to
standard ignition) does not work with
magnetic pickup distributors or crank
trigger ignition. • Inspect the primary coil wire connections.
Because the NITROUS 6 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 connections 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
NITROUS 6 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.
If everything checks positive, use the
procedure below to test the ignition for
spark. Mallory also offers an Ignition Tester
(PN 28357) that allows you to check the
entire ignition system while it is installed in
the vehicle. This tool also checks operation
of RPM limits, activated switches, and shift
lights.
