Turntable problems

Well, the turntable went back in okay and runs around fine.  The loco runs fine on it too…

but it won’t zero.  That means you can’t set the programming to work.  Instead it does this when it should rotate clockwise to the zero point:

The sensors look fine and clean:

rim sensor

Bridge sensor

Central feeders

I spent a morning turning the power of and off and checking the wiring and the feeders etc. I got nowhere…

It does look pretty though even if it is kind of useless…
