Please check this wiring schematic
Right...I need to install the electrics for my van after ripping them all out due to incompetant previous owners.
I've read loads of stuff and think I've got there, but would like one of you experts to cast your eye over this and tell me I'm right/wrong/in-different!
I've added fuse and cable sizes where I think I know them, but any suggestions would be appreciated.
thanks
Paul

Re: Please check this wiring schematic
What is the box which looks like it might say 'Relay' on it that seems to connect the split charge relay, the fridge, the 240V and 12v fuse box ...... ??

Re: Please check this wiring schematic
That's the relay which was in my fridge circuit originally. I thought that would enable switching from main battery whilst driving to leisure/mains when stopped.......but like I said, grease and spanners is more my thing

Agreed. This bit around the fridge relay is a little confusing.
If your fridge is a 3-way fridge, then the 240V supply can go direct to the fridge via an RCD, no relay required (You can always put a switch in-line if you don't want to use the RCD as a on/off switch).
The fridge relay is normally used for the 12V feed, to switch a direct 12V feed from the starter battery to the fridge, using the ignition as a trigger voltage. This stops the fridge draining the starter battery when the ignition is not switched on. Looking at the schematic there is a single output to the fridge (12v or 240v ?), but 3 inputs into the relay (Leisure Battery via the fuse box, Split charge, and 240v mains), I don't think this is correct. Generally a relay is used to switch a high current source on/off using a much lower current trigger. The relay trigger would need to be earthed on one side to allow the relay to close, thus passing the higher current (Assuming it's a normally open type relay)
I think most people avoid using the leisure battery for the fridge because of the high current it'll draw, flattening the battery very quickly.

Re: Please check this wiring schematic
This is kinda similar, but uses a manual switch to to control the trigger voltage.
The thick red line is the high current supply.
The thin red line is the low current trigger.

Re: Please check this wiring schematic
Thanks for the clarity. I knew that bit was suspect, hence the question marks around there

Re: Please check this wiring schematic
Depending on the fridge model, you may need a permanent 12v supply to power the ignitor when running on gas. That is very low current so can be connected directly to either battery.

That looks great Mocki....might be my eyes or a wobbly hand, but I can't read the text. Any chance of a better pic....or some glasses for me
Thanks

Re: Please check this wiring schematic
Occasionally, in deep midwinter when it is cheap enough or free.... Or to chill the fridge down prior to loading up for away , at home!kevtherev wrote:Do you ever use hook up Steve?
Up Untill the solar panel installation I did need to top up the battery's if we were not driving much , but Nothing in the van runs on mains other than the charger and PSU and the mains part of the fridge . Everything is 12v , couldn't see the point of having two of everything .....

Re: Please check this wiring schematic
Not used hooky since the solar panel was fitted Steve.
Even before then it was similar to you.
