I know some of you practically have the McMaster-Carr catalog memorized and thought you may be able to help.

I recently picked up, what I promise, is the most beat Profec B ever. That being said, it powers up with no issue.

For those familiar with the unit, the wire coming from the stepper motor has the plug attached. The wire coming from the head/control unit is cut with no plug.

Default, per my understanding, these had another wire that ran between the two with a plug at each end to connect the stepper motor to the head/control unit.

Anyone know what size the plug would be for the head/control unit wires and for the connecting wire?

Option B is just saying F it and cutting the plug off the stepper motor and running wires straight through.

Thought?

 

you do know they discontinued the original Profec B like 5 years ago?

 

Yep. Doesn't mean you can't find a plug somewhere that will work instead of just running straight wires. =)

It's a solid Boost Controller that a lot of people still use and love. You know that better than I. =)
