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

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.... - Tim - |

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. Regards Oldeng |
