Could be a bad connection or an open secondary (unusual). If it buzzes, the
primary is energized.

Are you talking about the actual transformer, or a power supply? People
often call a power supply (AC in DC out) a transformer, but techs are
talking the actual AC to AC part inside that drops the voltage down to
12 or so.

Just getting the full info....

I think the O.P. might be talking about an invertor (dc in ac out).

I would think he's talking about the charger for the battery but you
could be right of course.

yes, if you tell us the necessary info.

It could be any of the following:-

1, The 240 volt primary winding could be U/S
2, The 12 output winding is burnt out
3, The 12 volt fuse has blown

Try to get the manual for the van, it should contain a circuit diagram, if you can get a manual it is pretty easy to follow.
