Location: PA | Hi - my trailer has electric charge whenever it's wet. I get shocked when I touch the exterior. This only seems to happen during and after it rains. I'm taking it into the dealer today to have it looked at. Is there any advice I can give the service department in case they can't duplicate the issue (they've had this problem with other issues in the past).
Thanks for your help |

Location: North Carolina | Your trailer has an immediately dangerous fault. IF the service department can't find the cause and even if they do find something ... There is no guarantee what they find is the root cause. Get a GFCI to plug between your trailer and the electrical supply. There is NO normal electrical current flow to the frame of the trailer. Ground or no ground. |

Location: Minnesota | A friend of mine had the same problem. They found where a screw from the LQ installation had accidently nicked a 110 wire. Over time, the vibration wore through the insulation on the wire and was actually leaking onto his trailer. This actually took about six years to occur. His trailer is a steel frame with aluminum skin |

Location: Northern CA | Funny this came up- I have a little Nissan truck that I just bought about 3 months ago. It is a '91 and every single time i go to get out of it, It shocks the crap out of me. I have tried different shoes ,clothing etc. So I have come to the conclusion that something is not grounded properly. I took it in to a mechanic. He put new grounds on EVERYTHING and then even put grounds on stuff that didn't have 'em. It still is shocking me!! It isn't as bad as it was before, but is still happens. Any ideas??? I live in Northern Ca. Not a whole lot of wind but some breeze occasionally. |

Sounds like you're building a static charge as you drive. Try spraying static-gard on the seat (especially the back where you touch) of the truck. |

Location: Tenn/Ala. | For those that didn't re-read the thread. Buy & use an electrical tester! You can get them at Lwes, Home Depot, etc. for less than $10. We've seen this problem many times, and most are caused by a faulty receptacle where the trailer is plugged in. The LQ is basically just 1 large 30 amp appliance. If the hot & nuetral are reversed in the receptacle, this situation will happen. Yes, it can be the coach itself, but usually not.

Location: western PA | If it is not caused by the condition RTSmith described, it may be a combination of two problems. One is a hot wire touching the metal shell or grounding area of the trailer. As was mentioned, this can be caused by the shorting through insufficient insulation. The second cause can be a poor ground from the trailer, through the shore cord to the receptacle. I've seen people use the house hold three to two plug adaptors on the poles. By doing so, there is no ground circuit and an invitation for an accident. To continue using the trailer while encountering this situation, can be dangerous and the cause should be discovered, before any further usage is contemplated. Gard |

Location: PA | My plug-in tester didn't show any errors. This happens only when I'm plugged into 110. I use a RV surge protector on the cord from my trailer to the receptacle (sp?). The trailer is at the dealer. I'll let you know what they find. |

Location: Tenn/Ala. | As you've deduced (sp?), everything points to the trailer. There is a true test for what you've described that I've always heard called a Hi-pot test. One applies 1080 volts to the hot pin of the shore cord, and checks for bleed over to the ground and/or nuetral legs. If there is a nicked wire, it will generally show up this way. The certified LQ installers do it as part of RVIA & TR Arnold compliance. It does take a special tester to do this. We have one here at our service facility if it can be of any service to you. Drop me a note if you need any more info. Richard@SelectTrailer.com

Location: PA | The service department can't find anything wrong with the trailer. They want to examine the shore cord as a last option. |

Location: Where the wind comes sweepin' down the plain... | You said that your tester showed good. Was that at the plug or at the surge protector? Use it to test at three locations and you can determine if it is ground or not. Test at the main outlet. Test at the surge protector. And test in the trailer. |

Location: PA | The interior plugs all tested good. The electrical source at my home tests good. I can't test the campground source since I'm no longer there. But since this happened at two difference sources, I'm thinking its the trailer. |

Do you have a 30 amp shore cord or a regular 120 volt extension cord? A regular plug GFCI that will plug between your extension cord and the utility will cost about $30 A 30 amp GFCI will cost significantly more, but so is a funeral. |
