Halfords cool box

[thrifty]

Please be gentle, i'm new here.
I have a halfords cool box which I run off my 12v power supply on my wagon. Problem is shut the door on the cable, cutting the plug off. I have a new plug (with 8 amp fuse), but am unsure which way round to connect the plug.

Will it just blow the fuse if wrong way round? I can't open the unit to follow the wires into the casing to see which is which. On the cable, one of the cores has a black grove running the length of the plastic.

Help! I really need my "fridge" to keep my milk and beer cold. I can't live without coffee and beer!

Why don't you open up the old plug that has been cut off, as you have a new one it doesn't matter if you break it and find out how it was done before.

Great idea mate

you'll probably have a red and a black cable?
The red wire ( +) should go to the centre connection of the plug, and the black wire (-) should go to the side connections of the plug. Most plugs use soldered connections.

assuming you're on about a cigarette lighter plug?!

hope this helps

Unless it's been sealed after terminating and not screw terminals

Plug has gone after I shut door on the cable and drove down the road!

The cable is two black wires. Not a red and black.

does one of them have another colour running down the length of it?

 

[thrifty]

No, both cables are black. Even stripping back the plastic just has pain copper wires. Only difference is one of the black plastic outers has a groove running down it's length.

 

[thrifty]

No colours at all, black plastic outers over copper cabling. One core has a groove running the length of the cable.

^^^ yes sometime one has a white stripe down it.

 

[thrifty]

Definitely no stripe, red or white or otherwise. If it was wrong way round, would it not just blow the fuse?

 

[thrifty]

No both cores are the same

I spoke to a local sparky last night and he reckons it should be fine either way round. But he was drunk!
