Title: Electricuted by Car while tuning. Post by: eakinsj on October 01, 2016, 07:32:59 AM So last night I was changing the tie rod on my 2.7 and I though oh I can flash my tune while in changing the tie rod.
So I go grab my computer which has a terrible battery life. I plug the charger in and hook the compter up and I get the tune flashing. I reach in to start adjusting my tie rod and felt a shock on my left hand. I figured I just pinched a nerve or got stabbed by a piece of steel or something. So I reached it again. This time on my other arm I touched the fender and got shocked. So I went and grabbed my continuity tester and found that somehow the whole car was charged with a.c. power. And I mean the whole car. Any where with bare metal would electrocute you. Now I'm assuming it is an issue with my laptop but I am not sure. The tune flashed fine and car runs great. Just posted this to see what people think. And to warn them you're car could be trying to kill you. Title: Re: Electricuted by Car while tuning. Post by: vwaudiguy on October 01, 2016, 07:36:04 AM Was this car on a lift?

Title: Re: Electricuted by Car while tuning. Post by: eakinsj on October 01, 2016, 03:11:43 PM Yes. Blows my mind I just don't understand, how it is even possible. You would think 110 a.c. would fry the motherboard of the pc.

There is a filtering cap between the two sides. It's normal to feel a slight "nibble" if on any low impedance body part (sweaty hand/finger) due to capacitive coupling, but not a shock. Sounds like yours is leaking or isn't grounded properly.

Title: Re: Electricuted by Car while tuning. Post by: gman86 on October 03, 2016, 02:19:52 AM But for both to have failed? I suspect it's said "nibble" I was talking about. If true AC was in the vehicle electrical system, I suspect it would hurt some stuff. I've seen upto 90v float between the -ve output of a PSU and the supply earth. The problem is, there's absolutely zero current available so any sort of load drops that voltage to pretty much 0. Title: Re: Electricuted by Car while tuning.
