Everyone who has ever worked on the wiring of an older boat has
encountered a connection coated with green grunge that needs to be cleaned up and/or re-terminated. I just found a link to an interesting tip that sounds just like what is needed: http://www.instructables.com/id/How-to-perfectly-clean-wires-in-minutes/ It uses household chemicals like salt, vinegar and baking soda; and is said to act in minutes. In the comments section someone also mentioned using ferrous sulphate solution, (the one used to etch Printed Circuit Boards). I think that was available at Radio Shack at one time but I'll try the salt and vinegar recipe first. |

It has a mild acid in it. Wherever practical, you should replace the corroded wiring with tinned copper marine wire. |

Isn't the problem and solution the same as with corroded battery connectors in cars? Baking soda and water and coat the terminal and the connector and let it fizz. Wait a few minutes and the pour on some water to wash away the gunk? === With battery connectors you just need to neutralize the acid build up. That's where the baking soda does does its job. With old wires you first need to remove the oxide layer before you can make a good connection. That requires a mild acid which then gets neutralized with baking soda to stop the reaction from progressing. Harold's point regarding replacing the entire wire with a new run of tinned copper is perfectly valid but frequently very difficult, especially on a larger boat. |

We were having lunch at the Monkey bar yesterday and someone was talking about the iguana and monitor lizard invasion. Have you seen them in your neighborhood? |

If so, stop by and say hello. Maybe we can round up Gregg also. The Monitors are mostly down in the SW end of town near the Spreader Canal as I understand it. We're in the SE just off the river between the two bridges. I've never heard of Iguanas here but we do seem to have a bumper crop of Geckos this year. |

You could relay it to me through Mr. Luddite if you want |

One G Greg The Monitors are mostly down in the SW end of town near the Spreader Canal as I understand it. My wife ran into a 4' monitor in a house she was building in Crown Colony (South Ft Myers). She whacked it with a broom and it ran away. I think the iguana are up in the north end of the Cape, coming in from Boca Grande where they are thick. We're in the SE just off the river between the two bridges. I've never heard of Iguanas here but we do seem to have a bumper crop of Geckos this year. Do you mean Anoles? (the regular lizard you see running around the yard) Geccos are the ones you see at night with the big toe pads, usually very pale white. The main enemy of the anole is Herons and Egrets. If you have a lot of them hanging around, you won't have as many lizards. A Cuban tree frog and a black snake will take a lizard too. We had a black snake in our screen cage for a while and the first indication was that we did not have another living thing in there. This guy http://gfretwell.com/wildlife/Black%20racer.jpg http://gfretwell.com/wildlife/Black%20Racer%202.jpg I was kind of sorry to have to evict him but Judy said he had to go One of those suckers made itself at home in the pool screen area of the house we had in Florida. I tried coaching it out using the pool skimmer pole. Damn thing attacked it. Finally got him out though. Another time we came home from the store and I pushed the button for the garage door opener. As it was opening I noticed a black racer under our other car in the garage. I hate snakes. Then there was the time my younger son who was visiting from the Navy came in the house and told me about a snake that was out in our yard. We looked it up in a snake book I had and he recognized it as a Coral snake. But there's another non-poisonous snake that has similar black, yellow and red rings called a scarlet king snake. He and I took the golf cart out to see if we could find it and determine what it was. I took a CO2 pellet gun along, just in case. We found it. Sure enough, it was a Coral snake, the poisonous one. I damn near cut it in half just below the head with 12 shots from the pellet gun, standing 12 feet away. Even I was impressed. I used to have a picture of it somewhere. I think H*a*r*r*o*l*d has seen it. We also found a big rattle snake coiled up at our front door one day. I shot it with the pellet gun but all it did was **** him off. Went to Walmart the next day and bought a Winchester shotgun. (had to wait 3 days to pick it up though). We also had those damn pigmy rattle snakes around, plus an alligator in the little lake behind the pond and a family of Armadillos living under the horse barn tack room. Hmmmmm.... thinking maybe Massachusetts isn't so bad after all. |
