FAO people that are good at wiring

It could be a broken bit inside, you tried twisting it around etc? Im sure its somthing simple.

Yep tried that Ive even tried swapping the cig lighter from the saloon over just to check that thas not at fault, which it isn't, and ive checked the polarity many times and thats all good as well.

[AlexW]

So you're sure there is power getting to the block? or not? you checked all the wires?

put a bulb over it and if it works try seing if the live and earth are the other way round on the plug from the original ciggy one

[Steve]

It didnt originally have the wiring for a cig lighter so I pinched it from the clock, as the clock doesnt work. But ive connected a known working clock up to it and thats fine same with the cig lighter that works fine off of it.

But the in car charger or anything else that ive tried don't work on it. Thats what doesnt make sense about it, it works on some things but not on others!

[AlexW]

could be its not supplying enough amps/volts.

[Steve]

I had thought that but tbh wiring is a bit beyond me, I am ok with simple stuff but not sure on this one. Is it just a power and an earth it needs? if thats the case I could just wire it to run off something else.

[AlexW]

As far as i know, although i would put a fuse in.

Edit: Thought i would take a look in the haynes, it dont tell me the fuse amp it should have

[mowgli]

I reckon that the actual innards of the lighter must be worn or corroded, so the lighter works, but nothing else will. the 12v power stuff connects in a specific way & the lighter simply gets shoved in till it stops.

could be its not supplying enough amps/volts.

same thoughts
it will be just a pos neg but i'd put it on a simple switch with live fused closest to wherever you take it from
