Just ordered an grounding strap for 99 Odyssey
Our 1999 Odyssey has been shocking the heck out of us all winter.
We've had this vehicle for a few years now and I never remember it being this bad. I just ordered a "stop shock" grounding strap from eBay. I'm hoping this will help a lot. I called all the local auto- parts stores and not one of them carried this item. Anyhow, have any of you had luck with grounding straps? Mike |

Drain straps were fairly common in the 60s to stop static popping in AM radios. I think carbon additives in tires mostly put a stop to that. I've used antistatic sprays on the driver's seat before, and it helps for a day or two. I even got tired of brushing my knuckle against the latch, so I just live with the ZAP. Mike |

Carbon has been added to tires since about 1920. Carbon is what makes tires black. Absent carbon, tires are WHITE. Carbon (soot) was added to automotive tires to prevent decomposition due to ultraviolet radiation. It had nothing at all to do with electricity. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

That is because you drain off the charge -as it is generated- by your butt sliding across the seat. Now,with the insulating shoes,try to not touch the chassis and instead brush your knuckles against the ground and see if you still get a shock;I doubt you will. > I live in the desert southwest where it's > really dry, and that dryness probably exacerbates the issue.

Lotsa static
If you want to fix the problem you will have to spend LOTS of
money....... for new tires! This problem was noticed in the 90's when toll booth operators were getting zapped big time when getting tolls from drivers. It was blamed on the newer compounding that included more silica in the formula instead of just using cheap carbon black for filer. Actually I hope the addition of just a strap solves your problem. -SP Mike wrote: > Our 1999 Odyssey has been shocking the heck out of us all winter. > We've had this vehicle for a few years now and I never remember it > being this bad.

I'm confused about the draining off the charge as I slide across the seat. I thought I was building up a charge when sliding across the seat. (These are 2004 Accord EX cloth seats. I have had the same issues with previous cars: '97 Civic and '91 Civic.) And yes, my point was that with the "insulating" shoes, I don't need to touch the chassis in order to prevent a shock, as there is none. When you refer to "the ground," as in brushing my knuckles against the ground (which is how I normally walk) ;-) do you mean the concrete the car is sitting on? I suspect you do -- I'll try that today. |

This surface charge imbalance, which leads to static electricity, can be generated by touching two differing surfaces together and then separating them due to the phenomena of contact electrification and the triboelectric effect. Rubbing two non- conductive objects generates a great amount of static electricity. This is not just the result of friction; two non-conductive surfaces can become charged by just being placed one on top of the other. Since most surfaces have a rough texture, it takes longer to achieve charging through contact than through rubbing. Rubbing objects together increases amount of adhesive contact between the two surfaces. Usually insulators, i.e., substances that do not conduct electricity, are good at both generating, and holding, a surface charge. Some examples of these substances are rubber, plastic, glass, and pith. Conductive objects only rarely generate charge imbalance except, for example, when a metal surface is impacted by solid or liquid nonconductors. The charge that is transferred during contact electrification is stored on the surface of each object. Static electric generators, devices which produce very high voltage at very low current (such as the Van de Graaf generator or Wimshurst machine) and used for classroom physics demonstrations, rely on this effect. -- Jim Yanik jyanik at kua.net |

Insulating shoes would RETAIN the body's charge,conducting shoes would drain it(if contacting a "ground");that's how an anti-static strap or shoe works in electronics repair(I'm an electronics tech),it has a resistor and connects to a earth ground to slowly drain off charges -as they are generated- by your clothes. They actually make shoes designed to drain static charges,you have to be on a conductive mat or surface.they make static draining floor coatings,too. I had to take a anti-static course every year as part of ISO9000 procedures for my company,wore anti-static lab coats,wrist AND heel straps,and tested every day to be sure they were working.I used to work on equipment sensitive enough to measure the charge generated when I moved just an arm or leg when ungrounded. > > When you refer to "the ground," as in brushing my knuckles against the > ground (which is how I normally walk) ;-) do you mean the concrete the > car is sitting on?

Regardless, today I wore my "bad" shoes and got out of the car without holding onto the door frame. I, uh, dragged my knuckles across the parking garage floor, and when I touched my car there was no shock. Pretty good! However, I tried the same in my home's garage, which has metal rods in the concrete. When I dragged my knuckles across THAT floor, I got a shock. |

I am going to approach it as if you are not. When he said "ground", he didn't mean the ground you walk on. He meant electrical ground. IE the body of the car. Hold the door frame, slide across the seat and exit the vehicle, maintaining contact with the metal the entire time. You will not build a charge. |

I wasn't joking, because that is what he intimated. For years I have done exactly what you describe, and it is foolproof. Jim seemed to have suggested a different method, and, having tried it yesterday, it apparently does work (as long as there's no metal in the concrete!). |
