fridge relay ?

[dbz864]

Hi ive got a van which has a faulty fridge relay,the question is what type of relay are they,ive looked on ebay and there seems to be many different types,do maplins sell them?,electrics arnt my strongest strength.Ive always just started a fresh and in the past fitted them new intellengent thingys,but i was hoping just to swap it this time.It just works the fridge not a split charger.many thanks

Depends on the conversion I guess , but I would image it's just a bog standard 40 amp switching relay 4 config
Can you post a pic?

Is it the relay? My fridge stopped working a few years ago. The problem? An aluminium fuse that had corroded blocking the electric charge. I replaced this with a copper fuse and hey presto it worked fine again. Check it out. Take the fuse out, give it a gentle clean with a bit of wd40 and dry off, or fine sandpaper and put it back. Worth a try.

I can take pics but have lots of mither loading them on here,it does me head in trying so ive give up.The relay is defo shot as theres no output going to fridgey.The relay thats on is a a zig one,theres no numbers on the terminals at all,so me being a bit thick,dont know where to put the cables on to the new one.Any ideas,people?adam

Adam, send me the pictures to mocki@Club80-90.co.uk and I will upload them for you .

Failing that you will need a few mins with a multimeter to determine which is which

You will have a feed from the main battery , which will be live all the time
A similar size wire that is dead, that will be the feed to the fridge
A neg, which goes to chassis earth and a signal wire which only become live when either the ignition is on, or the engine is running .

Identify those and we can fix it!

Thanks Steve,i know where the cables come and go to,its just which terminals to put them on(on the relay),in the past the relays have had numbers like 30,80,87 etc(think there right),the old relay that isnt working hasnt got any numbers on.So when my new one comes im guessing itl have numbers on.Do you know which cable goes to what number(on relay).Sorry if this sounds nonsense and naive.adam

[Mocki]

Yes, it's like this
Perm live feed from battery to terminal 30
Live feed to the fridge from terminal. 87
Neg chassis earth to terminal 85
Signal switched live to terminal 86

Same as the split charge diagram but the fridge is the leisure battery
