Chescold 12v wireing (lost the lead)

One would be power the other earth return, stick a meter both ways to check for a circut. My guess would be blue for power.

If the 240 cable is connected check that.

How will the 240 cable help, AC is very different to DC?

I don't have mine at home at the moment, as suggested abouve try with a multimeter. If I had to guess, I would also say blue.

If all else fails go into your local camping store (or maybe ring chescold) and find out.

cheers

All the 12 volt connection is supplying is a heater element, so I'm not convinced that polarity matters.

Just had a look at a newer one and both wires are the same. I tend to agree with Penguin that it doesn't matter as the heater element is only a resistance.

Why not try an email to Chescold/Electrolux to be sure.Fidei defensor

NO!!!

Don't just whack it together! Two reasons...

1. For 12V, the cabinet could be connected to the ground-side of the element. This would make sense for safety reasons as it would also be tied to the earth for the 240V side (which I think they are). If you get the + on the grounded case, it won't matter until you sit the fridge in a vehicle, in which case you will short the battery and such... on the 240V side, there are more dangers;

2. If this loop occurs, the neutral side of the 240V supply could make it's way to the chassis of the vehicle. If the 240V supply socket or anything else connected behind that supply is faulty, you could be fatally injured by being the earthing rod out of the vehicle.

Do it properly, if there is any doubt, then there is no doubt - Get it fixed or get creditable information to do it yourself.

Sheesh! I repair these fridges. Polarity on 12V doesn't matter. It is hooked up to a aheating element (resistor), so it doesn't matter. The cabinet isn't earthed on 12V. The wires run directly to the element.
