I got a spilt charge relay to wire into a mk1 connect, i know there is a power cable with a plug already in the back with makes it handy, it has 2 wires on it a black and a red, does anyone know how to wire this to the battery?

I get i need to spice the wires but which one do I hook the the leisure battery?

Thought it best to ask instead of blowing fuses and god knows what else

Hi Ben

If you mean the 12V socket in the rear then the fuse is located behind the glove box marked "12v"  F46 15amp

I assume you could use this to power the Split Charger/Leisure Battery.

I've always run the pump direct from this power supply without fault, however I've no idea what "load" the cable is but I assume from the fuse it's probably at least 10amp.

No on the connect there is a redunant power source hidden behind the plylining has a plug on the end and it is live as ive tested it so it must be possible to cut of the plus and wire straight to the leisure battery via a fuse....there 2 wires i just dont know which wire i use for what.....cheers though

Yes. If you unclip the aux socket on the end of the wiring harness that is tucked up behind the horizontal middle frame, you will find that it has a black and red wire attached to it.

We spliced onto both of these wires and extended them to fit a split charge relay. Red = positive and black = negative.



The red and black wires on the left of the SCR are the positive and negative feeds from the supply socket.

The single brown wire on the right hand side of the relay is the supply to a 85amph leisure battery positive terminal.  We welded up a frame to secure the battery on the offside just in front for the rear wheel arch and bolted it to the floor.

We fitted a 15 amp fuse in the fuse box pointed out by John Willan. (The drivers manual lists the replacement fuse as 15 amps. I did see a photo of a fuse box which had a 10 amp fuse fitted and was curious at the time as to why this was.)  It has been in use for 4 1/2 years and never blown, even when the battery was flat and would draw maximum charge current.

The leisure battery negative terminal also needs to be earthed to the van's body or the SCR will not work.

Thats exactly in the info i was looking spruce cheers

You have the exact same relay as me too

Dead handy having the cable already in the back of the van ill get that job done tomorrow

Please remember to take the fuse out of the fuse box before you start. 

This SCR is near the rear doors mounted on the plyling in the van. To stop any drips of water (when putting the pole away) I made that cover out of a piece of plastic guttering. The SCR can be stuck into place with some double sided tape or I used a length of plastic that I slid between the electronic pc board and the out casing and screwed it together. This way it was easily removed.
