I have bought a new conversion from someone not au fait with all of it (had it done to sell). Everything works off the mains supply, but I don't know if the leisure battery works, or kicks in. It has a fuse type box mounted labelled 'F&S' with what looks like two mains fuses switches and a third single switch in a similar style with on and off positions. Would this one switch it between running off the battery or the mains? I can email a picture. Otherwise, where else should I look for switches, there appears to be no others. Thanks. Sev

Rather difficult to say without at least a picture (see here for putting pictures up), but that sounds like a Consumer Unit, which has a single isolation switch and two MCB's (Miniature circuit Breakers) which will control / protect the 240 volt circuits. You do have a standard 13 Amp 240 volt socket mounted somewhere ?
What and how the 12 volt L/B and its circuits are controlled is another matter altogether. You may (or occasionally may not) have a Relay that controls the charging of the L/B from the alternator, often refered to as a Voltage Sensitive Relay (VSR) and that will automatically control charging of the battery whilst your driving. Some installations also have a 12 volt charger / supply that is driven from the 240 volt supply and will charge your L/B whilst connected to a Hook-Up, usually this sort of set-up will have several other switches and fuses labelled in some way. If the conversion was a DIY job then rather difficult to say, if it was done by one of the Conversion Companies then you might get the best info from them.

Thanks for the advice, it does have an external power hook up, i know who the converter was so i will endeavor to speak to them. I an has been helpful too. Thanks for now. Sev
