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...
