So how does this cancel calls? It doesnt seem to show this.

I had a quick look at those prints and they do look like they are hard wired, but it is a little confusing as to how they cancel. From what i see they...

Have you tested the isolated motor phase resistances and insulation resistance?

If it consistent in both directions your stop contact and your selector may have moved or it got moved. Ideally you'd want to do a compounding check o...
