It has a pair of humbuckers with Mustang style three way switches above each one. The switches are used to switch between humbucker mode (switch in central position) and single coil mode (switch towards the bridge for the bridge side coil and switch towards the neck for the neck side coil).
The bridge pick up, however, now only works with the switch towards the bridge. When I switch to both coils or the neck side coil I get silence.
I know close to nothing about these things but I've done a quick visual check and everything appears to be connected correctly and nothing seems to be touching against something it shouldn't.
Any suggestions as to what I should look at / test / hit with a spanner etc?

This shows both pickups / switches. The bridge pick up is the one at the bottom of the photograph.
