Looking for Stator Testing Procedures and if any, Switch Box Testing Procedures. I basically have no spark. But it will, when I have my spark tester installed, get one spark upon initial crank over. Soon as I turn the key and crank the starter it will throw spark once. Continue to crank and nothing. Switch box was replaced 4 years ago but I know that really doesn't mean anything.

Oh...also with regard to stator testing please try to include the cranking RPM voltages as I have a DVA tester.
