Correction to the above (blurry schematic)…..contacts IV&I/II

Contacts I to VII info:

Contacts I&II make as do contacts IV&I/II when mains unit Z131 is fitted.

Contact III is battery -ve and Z131 (mains unit) -ve.

Contact V is battery +ve.

Contacts IV&VI make when battery unit (Z215) is fitted.

Contact VII is Z131 (mains unit) +ve.

So far as my eyes can tell...
