New 12v socket has killed 2 USB adaptors [Resolved]

Can you see where the wires go to, to see where it’s earthed at

 

[Sackmycook]

This is one of the others that works fine...

Unfortunately not

 

[Niknak]

Try probing the connector with that screwdriver and again touching the end ( o er ) and touching the body earth point, did you wire this in ? Nothing like using a common wire colour for earth

 

[Sackmycook]

Not my work I can assure you !
My son assures me my museum piece is not serviceable

 

[Niknak]

What about the screwdriver !

 

[Sackmycook]

is it worth swapping the wires on terminals or is that asking for trouble?

 

[Dellmassive]

an interesting collection of wire colours there.

you need a multimeter to tell you way around the wires go.

you can try swapping them over . . . (they have to go one way or the other right =] )

 

[Sackmycook]

Standby.....

 

[Niknak]

I wouldn’t personally I’d check,

You might be lucky and it work

 

[Dellmassive]

I wouldn’t personally I’d check,

agreed . . . but im thinking if that socket blew two USB plugs . . . then its very possible the feed is reversed. . .

so making an assumption that the wires are crossed.

and thinking he either needs to pay for someone to look at at . .

or pay to buy a multimeter . . . and fix it himself.

i wonder if writing this has given him enough time to test it?

 

[Sackmycook]

Ok....bear with me.
Swapped the wires....it works now but the other 12v now don't !
What does this tell me !! Be gentle

 

[Dellmassive]

so the only thing you done was swap these to over?





....



id shut the doors, lock the van.

then open and reset the points to see what's working.


.

 

[Niknak]

Do the others work when this one is in use I wonder if someone has broke into the wire somewhere

 

[Pete C]

I don’t think that there is much more that we can do remotely. It needs someone on site to look at it.

After swapping the 'faulty' socket wire back to how they were, it stopped working again, as I expected however the working socket also stopped working.
As @Dellmassive suggested, powered down and locked doors.
Put it all on again and it's back to how it was, faulty in rear, fine in mid-cab.

Will give the converter a bell in the morning, thanks for all your fine efforts guys

Next would be test with a multimeter - can you borrow one?
Too slow. Yours is a better plan.

Nice to see the converter tested their work

 

[Sackmycook]

Terminals wired wrong way around.....all sorted amicably by converter with free LED steplight bulb installed. Thanks for all the advice. Multimeter added to Xmas wish list

Screwfix have a nice cheap multimeter - I keep mine in the van on the basis if I carry it, I won’t get any electrical faults!
