Terminal 2 is a teardrop shape with 2 in it and the red wire is attached to it. What is the number in the teardrop under the red? If it's 5, then there are parts missing......like the terminal that sticks through small slot at 5.
Is there a 5 close to the black wire? I don't think the black wire is in the right spot. Could easily be wrong though.
Okay I just decided I'll give Grainger a call and see if maybe they can send me another one in the meantime I'm going to post thread on another motor I need help with, this one's an antique and it's a bit of a basket case
