Finding electrolysis at the dock

We never have had a DC connection, but when the ground was fixed, the zincs stopped going away. Huh? DC to the dock? I presume you meant AC!? I don't think you mean "brass" propellors. Indeed, bad translation in my head! ;-) But still, unpluging the shore power line when not needed can do only good and is a quick fix while the dock issues are addressed. Jean Dufour Montreal, Qc |

Finding electrolysis at the dock
"geneb321" wrote in message ... There is an excellent article on testing for grounding problems between shore power and boat at: http://www.yandina.com/electrolysis.htm I don't recommend following the instructions at that web site. Creating a potential safety hazard so that you can eliminate galvanic corrosion is not a good trade off in my book. You would also have to eliminate just about every piece of 110 volt gear (TV, ice maker, battery charger, etc.) or come up with elaborate ways of isolating them. Rod |

Finding electrolysis at the dock
Thanks for the input from everyone. One thing that is puzzling here.
Each slip is a separate home run to a meter. None of the slips are interconnected. Each is independent. If this is the case leakage from other bots on the ground shouldn't affect my zincs. We are looking for a source that is outside the AC connections. At least that is what I beleive. "geneb321" wrote in message ...

Our marina has a problem at some slips with stray current. Some of the boats are loosing zincs at a fast rate while others are not. Looking for some help in trying to resolve this and what kind of equipment will I need. Thanks. Chuck |

It will matter... if voltage is introduced to the water (from other
boats, bad dock wiring, etc) then it will flow to the fastest way back to ground... all the grounded metal (boats, etc) around it. Chuck Baier wrote: Thanks for the input from everyone.

Rod I suggest that somebody develop an induction system similarto that that was to be used with electric cars. No direct electrical connection to the boat so we eliminate thjis problem. |
