Split charge / fridge questions

Post by **spod_rod** » 28 Aug 2007, 19:56

Hello again, more questions if everyones not already fed up of answering my queries!

Anyway, I've been checking my camping electrics and can't quite work them out (been on wiki and it's not listed there either).

Right I have a fridge connected to either the leisure battery or the charge circuit via the standard split charge relay (no issues there!)
I also have a second relay which has the following connections (but no function diagram on the side to show me what's going on): -

a +12V charge circuit
b Earth
11 12V driving battery
14 not connected
21 not connected
22 12V leisure battery

Does anyone recognise this layout?

Second leisure battery charging circuit?

Think your right, spent a few hours drawing out the circuits. The first relay allows the fridge to work on 12V if the fridge switch is on and the engine is running.
The second relay allows the leisure to link into the charge circuit.

Thanks futurecut

ours has 2 "split charge relays"

one is for the charging the leisure battery, the other is for the fridge 12v.

Yeah looks like that's what I've got. The only thing that threw my is that the person who wired it up has used 2 completely different relays - a standard 4 pin and a huge 6 pin relay??

maybe a case of using what they had to hand at the time?
