Mike, I was thinking that myself about the sockets not mating properly but don't think that's the case. I fitted a brand new socket yesterday which I was told was better than original because there was much more metal inside the socket and should therefore give a better connection.... however, this didn't work either..

I'm going to go down tonight. How do I test the voltage with a meter with an appliance plugged into the socket? where do I touch with the earth and positive?

Cheers

I'd try using a volt meter and testing the voltage coming into the back of the lighter. Then I would take some junk 12v lighter adapter, cut the cable about 1 ft. back from the connector, split and strip the sides. then test Those connections to see if you're still getting 12v.

This is what I was attempting to say in my last post.

Well, after all that I tried taking the socket fuse out to see if it looked ok.... it did. I put it back in and..... Bob's your uncle! problem solved! both sockets are now working perfect! must have been a bad connection with the fuse...

Thanks everyone for the advice!

Cheers

Isuspect the fuse had oxide on its contacts that acted as a resistor limiting current and causing a voltage drop when you plugged into the socket. Removing and reinstalling wiped off the oxide.

When I was doing a more compputer hardware related role many years ago, we had to common unseat and reseat cards in servers and pc's for the same reason.

The light bulb in your charger will work no matter which way the current is flowing through it. Your device however, will not. It certainly does sound like the polarity is reversed to your outlets.

Actually most lights in portable devices are LEDs and they are polarity sensitive.
