My older craftsman inductive with power from the car's battery worked very good when there was not an MSD involved, but did not work very good on MSD. It had a tendency to jump around a lot. So I bought the MSD self-powered. It works very well with the MSD, steady as a rock. And the self-powered feature is very handy so I don't have to hook it to power when the battery is not under the hood.

Most lights won't function correctly with a multi-spark ignition. The adjustable lights aren't accurate when trying to use to check total timing with the engine RPMs up.
Old non-adjustable Ferrets, old Sears/Craftsman/Penske inductive lights (2134, 2138), and any of those sold by MSD will. Adjustable lights should be avoided. Plenty of the old Sears lights on ebay, and occasionally, an older MSD chrome light or even a Ferret 81 show up. Or you can pop for a new MSD copy of the Ferret, MSD also does a battery powered unit. I think they are still made in the USA

If the results don't match the theory, change the theory.
