Electrical problem..radio..leisure battery..split charge

[happypixie]

hello..heres what happened:

i have a leisure battery, which only the fridge was wired into. then i had a cigarette lighter installed and asked for that to be put in it along with the lights in the van. i collected her and he said they were all in the same pot as it were and so he moved everything over to the leisure..the interior lights, cigarette lighter and even the stereo.

all was fine for a while, but then the stereo suddenly went off just after a change of the main van battery. it wouldnt come back on but all the lights and cigarette lighter was still working. i took it back and he changed the little black split charging relay which was faulty and the stereo came on again..woo..

however, a week later, the same thing has happened! the stereo is off..the other little bits are working...why is this happening? cant really afford to keep going back every week and paying 30 bucks

any help on this would be greatly appreciated

Well firstly the interior (van) lights, stereo and ciggie lighter usually run off the van battery via the same fuse - although there is no reason you couldn't put them on the leisure battery if you wanted to.

The leisure battery usually runs the interior (camper) lighting, water pump and heating fan (if fitted). The fridge should NOT be connected to the leisure battery or the van battery but should only become connected to the 12v van system via a relay when the engine is running so the alternator provides the power. The fridge draws too much current at 12v to be ran off the batteries.

Either the stereo is seperately fused or has an 'in line' fuse that's blowing from the sound of it..............can't see why you'd feed it via a relay

First off your fridge should not be connected to your leisure battery.....
It should be connected to your main battery through a relay that opperates when the engine is running.
A fridge will flatten the battery in a matter of hours.

It sounds like ther is a loose connection somewhere in your radio wireing. Does it have a permanant feed to keep radio station info? Has this been swapped over to the leisur battery too?
As this first happened after changing the main battery I'd check all the connections to that battery are tight and clean.
