Thanks for the reply. Its doesn't really bother me, but I worry a little about corrosion as per the earlier comments in this thread and fire risk. My concerns may be unfounded though.

Steps I have no idea how you came to be worried about the earth/bonding  of the garage? the stainless steel in the jetski is described as providing the leaking voltage. 


As Cteks are double insulated they dont use an earth pin in the plug.

The voltage on the negative ( @ battery)is different to  the voltage of the ground your standing on  (potential voltage) Disconnect +ve and -ve from jetski circuits when charging if it bothers you...

Cant rem (without going out to the boat) if my ctek on the a/c side has a ground wire.. There is only +ve and -ve DC on the battery side , and dont know if the -ve is actually connected to a ground (if exists ) inside the ctek.

Don't know if it's relevant, but the power point is on the ceiling of the garage.


 Hmm so its all the time, a continuous tingle...
Garage.. assume metal...
 If not sure how to, get an electrical to check that the garage circuits, walls, anything metal is actually grounded correctly.
And side note: if had ANY work done on house or garage by an electrician, by law he must also check the grounding.
 That is how important grounding metal parts is..
 But so often they dont.

No and it's more sustained than static, as in it goes on as long as you make contact.

If one gets a tingle off a household tap or metal are, it usually means that there is a bad grounding connection between the item, switch board/ and the grounding pole / strap in the ground.

No.

My wife sometimes on some cars can get an very audible 'crack' and a kick like off the solar anti cat/ dog electric fence around the veggie garden.
Yet at best over decades at best on very rare occasions I may get a very faint kick.

Yes.

Correct, no isolation switch on the ski.

Guess the next logical move would be to try it with the battery in situ, but disconnected from the ski. Although, I'm not sure how useful that information will be given my lack of electrical knowledge.

I have little understanding of things electrical, but I ran a wire from the ski to the garage floor thinking it would solve the problem, but it doesn't. No drama, just wondered if anyone had any more thoughts?

The charder is a switch mode power supply, not an old double isolated transformer.
It is quite possible that a reference voltage to earth (and neutral), will be present.
If things are damp, and yoh have a small cut etc in your hand, you will feel 5 volts.
Crikey, you certainly feel 9 volts off an alarm battery on your tongue. Not dangerous, but never the less, you can feel it.]]> Fri, 30 Apr 2021 17:28:37 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=124840&PID=1807851&title=ctek-charger-getting-a-small-shock#1807851 <![CDATA[Ctek charger- getting a small shock : I&#039;ve never had this but I...]]> https://www.fishing.net.nz/forum/forum_posts.asp?TID=124840&PID=1807712&title=ctek-charger-getting-a-small-shock#1807712 Author: ofthesea

I've never had this but I only touch the terminals while in the boat and typically the tyres are dry on dry concrete.
Are you outside the boat and earthing yourself, that would explain things.
A but like getting out of a vehicle without holding the door and getting a shock when you close the car door
