Thanks, Gas Path.
just to complicate matters there are also some errors in the AMM for C.B locations as well!
That's true. I've noticed that myself. The Wiring Diagram Manuals seem to be the most reliable (and they put the "AC STBY PWR-TEST-APU-BAT" CB at J18).
Hopefully someone can tell me where SQ puts theirs.
Cheers.
Ian.
