on the monitor. You can select which alerts to show and how often. The alert is for Low Battery.
Fault: Program the number of counts that occur for a Low Voltage alert.
BrownOut 0: This is the count of low voltage resets. This should always be set at 0.
WatchDog: The count of Watch Dog resets. This should always be set at 0.
TEST
Can be set to spark On for normal operation. Set to spark Off to disable the output as an antitheft
setting.
TROUBLESHOOTING
Every MSD Ignition undergoes numerous quality control checks including a four hour burn-in test. If
you experience a problem with your MSD, our research has shown that the majority of problems are
due to improper installation or poor connections.
The Troubleshooting section has several checks and tests you can perform to ensure proper installation
and operation of the MSD. If you have any questions concerning your MSD, call our Customer Support
Department at [phone], 7 - 6 mountain time.
TACH/FUEL ADAPTERS
If your tachometer does not operate correctly or if you experience a no-run situation with your foreign
vehicle you probably need an MSD Tach Adapter. The chart below lists common tachometers and if
an Adapter is necessary.
NO-RUN ON FOREIGN VEHICLES
Some foreign vehicles with fuel injection systems may require an MSD Tach/Fuel Injection Adapter
to run with an MSD 6-Series Ignition. This is because many of these systems use the same trigger
source to operate the MSD, the tachometer and the fuel injection. This results in a voltage signal
that is too low to accurately trigger the fuel injection. To fix this, an MSD Tach Adapter, PN 8910, will
remedy the problem on the majority of vehicles.
Note: Toyotas and Ford Probes will require the PN 8910-EIS Adapter.
