A320 Master Caution attention-getter
When the master caution button lights up in yellow, but on one side displaying only CAUT (lower part of the button) and on the other side only MASTER (upper part of the button), without any sound or ECAM warning, what does that mean??
As I remebmer from few years back, it meant something like FWC doesn't function normaly or has some misbehaviour but I cannot find the reference anymore.

It is not burned bulb, I checked and I had it few times before
As I said and Chris Scott also obviously knows about this, it's something with FWC misbehaviour but I don't remember exactly what and there is no reference in FCOM. I think that it's in AMM but I don't have it
If I remember corectly, FWC1 is wired to supply Master Warning and Master Caution upper bulbs on CM1 side and lower on CM2 side. FWC2 does the opposite.
I would appreciate a reference

IFixPlanes - not quite....
AMM 31-00-00
For a more exact description, you have to infer the connections from what's in the Trouble Shooting Manual 31-53-00. The top globe of the Captain's MASTER CAUT is troubleshot with replacement of FWC 1 and for the lower globe replacement of FWC 2. Vice Versa for the CM2 station.
AMM 31-00-00
the two FWCs and the two SDACs are identical and are configured in such a way that all the master warnings and cautions are still operative in case of one FWC and/or SDAC failure.

No - quite right!
If you read my posting carefully, you will notice that we write the same thing in different words.
(but i have to admit, that i leave out the word "part")
