I have a newish car and both myself and my wife get a shock each time we get out of the car, i know there used to be a strap that you could bolt onto the bumper of the older cars but of course the new cars are all plastic bumpers. Does anyone know of a good cure or product that would help? Thanks

Strap doesn't work! The metal in the car is drawing current out of your body like a big negative terminal. I noticed this happens in the summer a lot, it depends what footwear you're wearing and type of carpet is in there. I'm so used to it now, I hesitate before I close a car door.

I got this a lot with my '90 coon wags for a while. Put it down to a combination of plastic soled office shoes and synthetic seat covers. Doesn't do it now with the same shoes, same seat covers, only change is the amount of dirt on the driver's mat. Maybe that makes a difference. Can't see how though.

WANRING, basic and likely unfounded knowledge coming in fast!
No it shouldn't work, because the car is already grounded. What's happening is a charge from your body is actually crossing to the car because its grounded. You would be better tapping a metal pole in the ground before getting in, than wasting money on a strap that will just wear away.

I used To get this with one of my cars (can't remember what one) I found the best way round it was in the way you get out of the car
Hold on to the car (sill or B post) as you get out so you earth from a large area and not your finger tip

Duhh, of course. I got that completely backwards in my head. Still stands though I cant see how the car is generating static unless you've swapped everything for shagpile.

For the benefit of non New Zealanders "coon wags" translates into English as "Ford Falcon estate wagon".

Not just me who thought it was something to do with a racist reference to footballers wives and black guys then? LOL Anyway. The amount of curse word that gets sold because electricity is regarded as some sort of magic astounds me! So. Let's bust this wide open. Static is generated by many moving parts. You are physically pushing electrons around when certain materials rub. The planet earth has an electrical potential (typically, but not always, 0v, but its still a potential). When you push electrons around, you create a potential. Electricity, like water, or air pressure, always wants to equalise (that's why we get wind, or flowing rivers). Your nice shiny new car is doing a wonderful job of pushing electrons around through the various frictions going on, and your bottom is helping too with rubbing on the seat (especially when you " borrow" your wife's soft satin knickers cos its washing day and you are out of clean skids). When you get out of the car, all those electrons that have been pushed about creating a potential want to get to earth. They cant cos the tyres are in the way. When you get out of the car you create a much handier path of less resistance to the lower potential of earth (fudging a bit here because electron flow is actually reverse to conventional current, it doesn't flow from positive to negative. That's just a handy fib to make electrical circuits easier to understand). That's why you feel the shock. Putting straps between bits of car change nothing. The ONLY way you can discharge it is with something connecting the car to the ground like a bit of cable (remember those trailing bits of rubber you used to see hanging off the chassis?). Your chassis, by the way, is still earth as far as your car electrical system is concerned because if you have a static build up of, say, 10,000 volts relative to actual planet earths 0v, that applies to the whole car. So your chassis is at 10,000 but your cars +I've is actually 10,012v (or 10,014 if you wannabe clever and point out that its charging). Why do you not get a huge belt when you touch anything that is 10,014v live in your car? Cos your body is at 10,000v so the POTENTIAL is still 14v. But step outta your car so that your body is now 0v, that's where you get the static shock. Helicopters have a serious problem with static. The build up from the spinning rotors is of lethal potential. They drop a static line to ground when doing winch stuff because of this. Any minute now a smarty pants will come along to point out omissions and fudged details that I've deliberately left out.

I use either a bit of old thin chain or some scrap cycle cable inner. Tied onto the exhaust or back axle. They wear away over time but since it's scrap stuff it doesn't matter.
The alternative is to always be a gentleman and let the wife get out first.

Get hold of the door top first, then put a foot on the ground.

thanks for the ebay link but as i have a plastic bumper there aint much metal at the rear of the car to attach it to. My thinking is that if i attach it to the exhaust it wouldnt work as the exhaust is all rubber mounted, so ill have to find something metal at the back of the car or it wont work (thats if they work anyway) But i suppose they are cheap enough to try
