THEFT DETERRENT

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 - 5 mountain time.
LED
The LED will flash for every trigger signal from the distributor or crank trigger. You can take advantage
of this when statically setting the timing when false triggering the box to troubleshoot. Also, when the
engine is not running, the LED will be On when the key is in the On position.
