I’ve pulled the end plate off the starter motor this morning and note
1. The end plate can only go on one way due to the stud connection hole and a notch in the end cover which lines up with a mark on the main casing.
2. Note that the brush gear can be partly rotated and clamped by two screws accessible from outside the end cover.
3. The flat screw that attached one brush to the casing was loose, not tightened up.
4. The brushes are brand new, indicating that someone, not me has been inside the motor. A tiny bit of wear is showing compatible with the few times I’ve run it backwards.
5. The lead clamped to the casing looks wrong, facing the wrong way? So will try to turn it round and see if it can reach to the other brush holder.
6. Will also check if the flying lead from the field coils can reach the other brush
If 5 and 6 check out I’ll reassemble and try putting power on it and seeing what difference the adjustable ring plate makes , which by the way carries both brushes in a fixed relationship to each other
Here goes!
If 5 &6 don’t check out , a rethink is required?

On close examination the earthing lead cannot be turned round as it
would foul one of the long securing bolts.
But I’ve realised though that I can turn the brush mounting plate 180 degrees
and that looks to suit the earthing lead so now will go out to the garage
And check the flying coil lead can reach the other brush.
I’ve a feeling this will solve the puzzle!!
Update coming soon!
