This looks like a typical issue with the interact 1 mk 2 spindle.
My spindle fan turns on OK when you press cycle start.
I program S100, M03, press cycle start, hear the contactor, but the spindle wont start.
I've replaced the cap underneath the medium sized xformer on my MTI-1 board, along with two resistors and two diodes.
I get the INS TRIP light after I give the spindle on command.
I've got the bport maintenance manual, but I'm certain it doesn't cover the issue I've got here.
Any help would be greatly appreciated. The machine is in otherwise very good shape.
I've seen that George has put out the KTK drive maintenance manual to others in the past, I would really appreciate a copy of these materials, it appears to have helped pretty much everyone before.

Also, does anyone know of a good way to test phase rotation? Im running on a 20 hp RPC, i've already tried swapping some leads, but with no result yet. It would be good to know a test procedure to KNOW that i've got the phase rotation correct.
thanks guys.
