Split Charging Relay

[windysurfer]

I'm in the process of changing my 240v fridge to a 3 way fridge.

I currently have a split charge relay fitted to charge the leisure battery.

I have just bought a "Combi Master" split charge relay, which is really for use with a trailer socket, but I'm a bit unsure of the wiring.

It has 6 connectors numbered 6 to 11

6 - H/Duty 12v
7- Earth
8 - 12v Ign
9 - Fridge 12s
10- Batt Tr 12s
11 - Batt Chg

I've read the distructions but just want to make sure I've git it right before I start.

6- 12v + on van battery
7- earth
8 - can I use the blue wire which come from the alternator currently used on my exsisting set up?
9 - to fridge
10 - don't think I need it ( for battery in trailer in instructions)
11 - to my lesuire battery

does this sound right?

cheers

just had a look how my current relay is wired up and noticed it has 5 pins on it.

Checked the 5th unused one and I get 12v when the engine is running.

Now to sort out the gas supply

you need
12v supply from MAIN battery
12v signal from blue wire from alternator
12v feed to fridge
-12vdc (neg) from vehicle body or battery

fridges shouldnt be connected to leisure battery, or their power is 3rd hand.....
