12v socket mystery

[brian62c]

Hello all,

 

Daughter's Citigo 12v socket popped its fuse so her dash cam is out of action, much to her distress.

I've replaced the 20 amp fuse 46 - which was clearly broken - but no joy.

It's not the dash cam itself as I've tested that in my Octavia and it works.

It's not the socket either, as I've swapped that into my car and it works.

Any suggestions please? I'm no great technical/electrical wizard btw 🙄

TIA

Have you swapped the fuse or has it blown again?

 

Is there any voltage behind the 12V socket?

 

Do you need the ignition on?

 

Thanks. AG Falco

I agree with AGF.
Also, it's possible that something has come loose in the cigar-lighter style plug for the dash cam, but didn't show up when you tried it on your car - or could be that the sprung centre contact is faulty (really common), OR something metallic like a washer has dropped into the socket (check fuse again).

What year is the car?

Did you mean to write fuse 36?

[brian62c]

It's 2016 (16 plate).

 

The post I found about which fuse for the 12v socket said 46. Don't tell me I should be looking at 36! 😳

[Breezy_Pete]

Have a look and see if 36 is bust.

Swapped fuse 46 and it hasn't blown again - but the dash cam still isn't working. 

Don't know about voltage - haven't got a meter.

Tried with and without the ignition on - no joy.

Also tried a different dash cam - nothing doing.

For sure they don't seem like the most robust of items but I have tried them back and forth several times and with the sockets swapped from car to car.

No foreign bodies inside either socket.

I'm on it .....

[brian62c]

Okay, fuse 36 is a smaller size and only 10a so I'm guessing not right for the 12v socket. It's also completely intact.

[Breezy_Pete]

Oh, OK, if you're sure you've got the numbering right.

LHD/RHD confusion often arises from single diagrams in Owner's Manual?

Fuse 36 comes up as licence plate light when I look it up?

Should be 2nd one from left, bottom row?

 

[TMB]

Sorry, looking at Fabia. Wrong car 😋

[Breezy_Pete]

Hmm, diagram I'm looking at may be wrong one, what does your fusebox look like?

Not like that apparently 😏

46 is bottom row sixth from right.

[Breezy_Pete]

And 36?

 

[brian62c]

Breaking news: It's bloody working now!!!

 

Tried both cameras again in the Citigo. Spare worked, original didn't so swapped the little clear cylindrical fuse in the end of the plug-in bit with a spare cable I had - and that worked as well!

 

It does need the ignition switched on (just so the dash lights up) - which my Octy doesn't - but I definitely tried that before and it wouldn't play ball.

 

Baffled, to say the least 🤔

36 is possibly second from left bottom row - but it's a little 10a fuse.

[Breezy_Pete]

All's well that ends well.

Yep, Citigo is a rare exception to the 'permanently live ciggy socket' situation on most VW group cars

[Breezy_Pete]

Looks like there's a gap in the erWin Skoda circuit diagram coverage of Citigo. Document I have (where it's fuse 36) only goes up to late 2015, the only other one on there seems to be 2019 onwards. Odd.

 

[brian62c]

Well, all I can say is apologies for wasting everyone's time - and thanks for the suggestions and moral support.

It's clearly good to talk 😊🤪

There may well be a relay involved, which possibly has slightly worn contacts; that might explain intermittent function, maybe.

I did wonder about that kind of thing, thanks BP 🙂
