you said new batteries with a full charge.

close it or depending on the type of switch tie it closed and try?
if thats not it check all emergency exit switches like windows and roof hatches.
the roof hatches are notorius almost like if you ever open it then the hatch needs to be replaced.
if all of that checks out and you still get a click when you turn the key.
block/chock your wheels have someone inside turning the key and tap on the starter with a hammer while the other person is holding the key in the start position.
check the cable ends from battery to starter/signal and ground for cleanliness.
and you could also pull the starter and have it tested. its a heavy little thing so dont be under when the last bolt comes out but dont want to drop it either.
i assume you have a vandalock system on your bus?
do you have child check buttons front and back that have to be pushed,have you clipped any orange wiring???
