Hi list,
Quite by chance I noticed that the '5V' LED was lit on one of my
busbars, and which I knew did not have a source of 5V connected to it
(i.e. no AD5). Measured the voltage on the 5V rail, was 12V, not 5!
Traced it back to one of the ribbon connectors with a 10-way ribbon
in a 16-way socket - the 5V connection (which should of course been
unconnected!) had pierced the edge-most wire in the cable right next
to it, thus sticking 12V on the 5V rail. Erk! Sure glad I spotted
that before a major module reshuffle I plan soon - wouldn't have
wanted my A-190 connected to that bus!!

So, keep your eyes peeled!
