split charge help

[mr.mono7]

Hello all,

After a bit of help with the split charge relay wiring on my 1983 Cathargo. I bought the van last November and I've been busy with the bodywork and getting shut of the rot and I'm now ready to start putting the interior back together ready for the summer. The van already has a leisure battery installed but the previous owner disconnected everything??

I've read up on how it all works so have a reasonable understanding but the way mine's wired seems to contradict everything I've read:

The van has a 70amp relay installed. I traced the wires back this morning.

The '37' output goes over to the starter battery via a 30amp fuse

The '30' outlet goes to the leisure battery - no fuse

The '85' outlet goes to what I think is the switched live from the alternator - spliced into blue wire behind fuse box

The '86' outlet isn't connected to anything?

I can easily change everything by reconnecting the spades at the relay but wonder if anyone had thoughts on how its wired currently?

Additionally, there's a wire that comes from a 40amp fuse in the main fuse box and is routed into the leisure battery area under the seat. Again, its been disconnected. Any ideas as to what this might have been used for? It comes from the 4th fuse from the left (noting van is left hand drive).

Hope someone can help then I can get this thing on the road in time for the great British summer!

Many thanks

Regarding 40amp fuse. Its 4th from the right, not the left.

Thanks

86 goes to ground.
Then it will work.

Ah, thanks. Will give it a whirl and hope it all fires up. Don't understand why someone would disconnect everything in the first place?

Any idea what the wire coming from the 40amp fuse might be for? It comes down through the same shrouding used to house the wire which runs from the relay to the alternator feed.

Who knows what has been removed before it was sold, aux sockets, heater ie propex.

No idea what was in, there's nothing in there now and I'm planning on keeping it that way really. Just gonna put the bed and rear storage back and and leave it at that.

Thanks for the info, much appreciated.
