Can you share with me how I can test my MSD 6AL box? I have also installed a MSD timing control box on the car as well.
Thank you,
Rod

The way to test the MSD Unit, you will disconnect the white wire from the yellow on the timing control.
Disconnect the coil wire at the distributor cap and lay 1/4 from ground, this is where it will spark.
Turn the ignition key to the "ON" position, do not crank, make sure there is 12 volts at the small red wire of MSD.
Take the white wire of the MSD 6 Unit and touch and release from ground, every time you touch and release from ground it will spark at the coil wire.
If you do not get a spark, swap the coil with a different coil, it doesn't have to be new, as long as it is a good working coil.
Do the same test, if you get a spark then it was a bad coil, if you still do not get a spark then you know it is a bad MSD unit, but double check that all connections are good and tight.
Thanks,
