I did get something cobbled up that seemed to work nicely. Fwd worked, stop worked, reverse worked, and stop worked, several times. So I thought I'd test the lockout by trying to reverse before it had a chance to stop from about 20 rpm, by clicking stop, and immediately clicking reverse. Blew something in the controller itself, motor doesn't run, and an led that flickered to indicate an scr trigger was occurring now remains dark at all commanded speeds. It also has a control signal present tally led, and that one goes on & off as expected. And that puppy is a very complex, not a lot of integrated circuits in it, bit of 20 year old tech, and didn't come with drawings. I'll pull it back out tomorrow & do some cold checking. But I may be forced to go get another controller off ebay. Where's that Murphy guy?, I have a box of 30-06 Ackley Improved shells with his name on it.
