Whilst working on the car I noticed I got a mild electric shock when my face touched a metallic part it the car. I turned off the battery conditioner and it stopped. Should this be happening?

[VXT Tim]

The shock or rubbing your face on the car?

IMO neither should happen

 

 

 

Mine is on charge all the time and i have never been shocked touching any part of the car.

[oakmere]

I thought everyone did this? If I touched it by hand I didn't notice much but whilst climbing into the wheel arch my face made contact with the brake disk and got that tongue on a 9v battery feeling.

My conditioner is a cetek and I have never had a problem
You wernt touching it with anything wet were you 😃

The charger only gives out a very low voyage 13/14 v and you can't feel that, more likely to be a little static possibly .

dodgy ground loop between the ring main and the car

[oakmere]

Yes sounds the most likely.

mines exactly the same, usually when my head touches the rear diffuser

Are you plugged into 240v or 415v ?!

[Hammy of hamhouse]

Check the plug wiring carefully and that the live / neutral on the supply are not reversed on the socket. Check the earth is ok too !

[oakmere]

It's not just me then Vocky! I will check the wiring on the mains side. It goes via an extension cable which may have a faulty earth. Forgot the multimeter tonight so will check tomorrow. I have never noticed this untill recently so assume it is a fault of some kind.

And besides metal parts on the car are likely to be ground anyway. If you got a shock some dodgy wiring somewhere.

1stly electrically for the car the world would have ended and secondly even if that was the case it wouldn't give you a shock. Yes the car is 12v but when connected by a potentially dodgy mains setup I to the ctek you might be offsetting the 'ground' of the car to give you a shock, it not killing the car as its still only a 12v system

Unlikely I would have thought of mixing live and neutral would have affected the output. 

[higgins]

having live and neutral reversed is of no consequence as it is ac. problem is with the conditioner.

[deano01]

Can you post a video clip of this happening please.

Really.... Really..... And you of all people think that's true. Oh my. The charger is dc, its powered from the mains. The dc going into the battery will have the ground derived from the mains, now if there is something screwy with your home mains say having a bias in the neutral then you could raise the car ground to something which would tingle. Ether the charger is naffed or the mains has an issue.

[turbobob]

Seriously? If the mains is anyway connected to ground I'll eat your balls. 

 

Chances are its a switch mode power supply. Or it is old school then bridge rectified. The ground will be isolated from the mains. Most appliances will still work of live and neutral are swapped. It just becomes less safe. 

[higgins]

its the charger, nothing to do with the mains

 

[slindborg]

So, pray tell, where does the charger derive its '0v/ground' from then...... Do we atleast agree its not that the 12v and ground have been swapped magically
