Two Brothers Racing Suzuki LTZ400 Dyna FS Ignition - Manual (Page 3)

Troubleshooting the Dyna ignition is simple. If the bike will not start or run at all, reinstall the stock ignition. If this fixes
the problem, then the Dyna ignition should be returned to Dynatek for testing. If this does not fix the problem, then the
problem is somewhere else on the bike. Follow the troubleshooting procedures outlined in your bike shop manual.
If the bike runs, but poorly, put the stock ignition back on the bike. If this fixes the problem, reinstall the Dyna ignition. If
you are using non-stock plug wires, plug cap, ignition coil, spark plug, or stator, replace them with OEM units. Then follow
the procedures in the calibration section to set the Dyna ignition up to work with your bike. If calibration doesn't fix the
problem, the ignition should be returned for testing. If the problem persists when using the stock ignition then the problem
is external to the Dyna ignition. Note: The Dyna FS ignition for the LTZ400 uses the 12-pole “rotor rotation detection”
signal for accurate RPM information. If this signal is lost, the ignition will resort to TDC firing at all RPM. The engine
will feel sluggish and won’t want to rev-out. Follow the test procedures outlined in your bike shop manual for the Signal
Coil to pinpoint the problem.
WARNING:
Installation of a grounded tether kill switch to the ignition coil signal will
damage the CDI and void the warranty.
12V DC-CDI (LTZ400/KFX400/etc.): Use a normally closed tether kill switch connected in series with the
+12V input to the ignition. When the tether is removed, it should disconnect the +12V power to the ignition.
LTZ400/KFX400 +12V POWER INPUT: BLACK/ORANGE at the ignition module.
The RUN/STOP SWITCH is another +12V input into the ignition module. Either wire (ORANGE/WHITE or
ORANGE) can be disconnected to remove +12V from the ignition.
