Techwest Racing shows a test for MSD ignitions as shown"
"" How to check Your Msd Ignition Box For Damage For the Racer who feels they have a failed MSDŽIgnition, there is a simple test that TechWest Racing Services can walk you through to confirm a true failure of your MSDŽIgnition.

First you will need a Volt/Ohm meter (this check can be performed with an analog or digital meter as well). The type of meter will not change the outcome of the test performed. Set your volt/ohm meter on the 1k ohms scale, then position the MSDŽIgnition in approximately the same orientation as mounted in the vehicle. This is done to ensure that the MSDŽIgnition is relatively in the same position as when the failure occurred. Next take either lead and attach it to a bare metal area on the MSDŽIgnition. The second lead needs to be hooked to the Large Red wire that provides your main 12vdc input. In an Undamaged MSDŽIgnition the needle will stay in the home position (ie. max Ohms for scale chosen). A Damaged MSDŽIgnition will show a reading of 3k ohms or lower.

The readings mentioned above are the result of our experience with repairing customers MSDŽIgnition systems. If you plan on testing your MSDŽIgnition while it is still mounted in your vehicle PLEASE remove the LARGE RED wire (ie. main 12vdc). Failure to do this will result in possibly damaging your meter while performing this test on your MSDŽIgnition.""

What do you think?
Removing the BIG RED wire from the battery and checking continuity in the box? How would this hurt a meter?

Thanks
