hi jef
van electrica are fine ...the volton combi relay i am using is a relay which auto switches on the charge on the batteries only when the van has started so as not to draw current back all the charging seems to be working fine ie the different voltages and switching is working.
its just the relay melted.
its wired cos when iused a thinner wire the wire got hit and fuse melted then put a thicker wire in and the relaydecided to melt.
i know its simple for me to buy another relay like the one tony showed but the thing is whats stopping that one from doing the same.
i went to a auto electrician and he want 200 to wire up the lot thats wit my own battery and relay?
so thats a no no

Shawn as I said if your van electrics are fine, then some thing is pulling to much current through the wire, and by adding a thicker wire is just like adding a larger fuse, some thing is going to burn or catch fire, reading what your saying I would suspect you have a faulty battery, take your battery and get it tested, should only cost a couple of quid and some places do it free. or if you have a good spare put this on and see if every thing runs fine but keep a very close eye on it.
I strongly recommend you get it all tested.
£200 is way over the top, I'm sure the guy's on here don't pay any thing near that price.
Tips: if you suspect an electrical fault, do not increase cable or fuse sizes, this can lead to fires.
Does the wire between the battery and the relay get hot?(your working battery not your van battery) if yes then this is a sure sign of a faulty battery drawing to much current. if the answer is no, then the fault lies in the relay it self.
