Starting cap

[cowboychuck]

Will take a look tomorrow- till then... does the machine have a control box with contactors, transformer, etc.? Picture of that would be good also
Used to own a 1984 633csi, good freeway car
Had to let it go

everything in the box is wired right per a wiring diagram, I used to own a 1980 633csi got rid of it about 4 years ago but I still got my 650i best open highway car I have ever driven 135mph so far then the wife starts to get scared

OK try this: Install your new cap. Disconnect the one yellow wire as shown and insulate the end with tape or heatshrink tubing.
Wire motor as per diagram.
Connect 240 volt power to R and S (leftmost terminals in control box; don't forget the ground wire)
If the rotation is backwards turn off power and swap the two red motor wires.

Edit: correct for phase swap as per the cover diagram in post #25

If motor just hums or spins slowly we may have to backtrack and ohm out the motor wires 1 thru 4 to ID the windings

sorry, I forgot to give you that info, 1 and 2 are connected and 3 and 4 are connected 1.0 ohm on both, so your diagram is correct I assume

OK, should work then as drawn. There is a slight chance that they still might be out of phase but swapping 3 and 4 would remedy that
The factories sometimes do things backwards but fortunately not often
Edit: check drawing for update

uh just found the motor wiring cover, i still dont understand this but i do understand your drawing

Aha! Those stinkers. You'll need to swap 1 and 2 (I'll correct the drawing)
The motor cover drawing shows the basic phasing connection to power for the 2 main windings
The start circuit isn't shown- not sure why.
With import stuff one has to expect goofy, incomplete data sometimes

Bingo, that did the trick, Its spinning now thanks for all of your help I think Im gonna try and turn something now
