I think I maybe having problems with something on my van slowly draining my battery (Battery problem post) I'm thinking of fitting an isolator switch I'm pressuming this is a fairly simple task, Does anybody have any tips?
yes i fitted one in the battery box,it is not hard to do and cost about £5 for the switch.i fitted one because of the mover switch that had been placed under a seat!!!!!.buy some battery jump leads to obtain the thickness cable required and some large eye connectors and a connector crimper.only a heavy duty switch will do.your 12V RED lead from the fuse box goes to one side of the switch and a new RED 12V lead goes to the battery positive.check your alarm does not need a supply from the battery. www.ukcampsite.co.uk/redirect.asp?redir=http://www.towsure.com

That is exactly like the isolator I used. In my caravan, the battery box and cable entry from it is under one of the front seats.
There was quite a bit of cable slack, so all I did was cut the red cable coming from the battery then strip the two ends and connect them to the isolator. If I remember rightly, I also made a bracket for the switch so that I could fix it to a nearby timber batten.
Simples ......
If you decide to get a small solar panel to keep the battery topped up in storage (I have a 5W panel), you'll need to strip about an inch of insulation from the black cable coming from the battery box. You can then connect the solar panel's black croc clip to the copper you've just exposed and the red one to the battery-side isolator terminal.
If you position the CAR VAN rocker switch at the mid point (ie off) you may resolve the problem. In the other positions there is a relay engaged which will drain the battery in a couple of months. (It can be heard clicking in and out)
I undid the leadfrom the battery and as I dab it on the battery terminal I got a very small spark. When I switched off the DC switch on the control panel, there was no more sparking. Sparking like this means there is a current flowing.
as an alternative you could fit quick release clamps on the battery as you only remove the black/blue cable but do not let it touch the body of the van.only takes seconds to fit once the clamps are added.
You could fit quick release clamps, but then you would have no ready means of attaching a small solar panel to keep the battery topped up when in storage. You'd still have to remove the battery for occasional charging - at maybe monthly intervals.
