Help with a 12 Generator rebuild finger pointing fiasco

[coolairX2]

So my 12v 356 generator bit the dust. I found a rebuild kit online that seemed to be exactly what I needed.

As I was pressed for time I dropped it and my genny at a local auto electric shop specializing or so I thought in generators etc.

Spent a lot of time reinstalling only to find the same red light and no juice coming out of the genny. I tested it by setting DF to ground and D+ to 12v and found it spins backwards ie counter clockwise. So I believe that is my problem.

The supplier of the genny parts claims the shop reversed the wires. But when I try switching wires D+ wire to ground and DF to 12v it doesn't spin at all.

The shop claims I must have gotten the wrong armature . The genny parts supplier seems to be knowledgeable in these Porsche generators so I tend to believe him.

Any suggestions for what the local shop might have done wrong?

did you follow the polarization procedure in the Bentley manual?

Yes polarization was done. Of course based on the current wiring it is polarized backwards. The vendor claims I can simply switch the wires and repolarize.
When I tried that nothing happened it did not spin at all.
