HelloSailor et al...
Thanks for the suggestions. It seems the problem with our Link 10 was twofold. Foremost, the original wiring
wasn't done properly and what was done was so with over sized wire that could not be properly connected to the device to make secure connections. Since our last post, Rick Young--a member
of this board and the designer
of much of the Xantrex equipment
we all use--has given me quite an education on his gear
. Among other matters, the differences measured by the equipment
are so tiny that a variation induced by nearby electromagnetic influences--which the twisted wiring
apparently defeats--can have significant impact on the results reported by the equipment. Garbage in, garbage out.
Being able to take accurate measurements with a Fluke, or other meter, are all well and good, but inefficient. When we go aboard the yacht, I simply want to be able to look at an instrument panel and see the state of our batteries, which the Link 10 and Link 1000 will do admirably if they are properly installed.
Subsequent to getting the yacht in the water
, Electrician 2.0 reported that while the Link 10 then seemed to be working properly, the Link 1000 was reporting erroneously and he suspected a problem with the device. While I doubted that, I sent it off to Xantrex and was informed, yesterday afternoon, that one or more of the chips was, in fact, fried--damage most commonly caused by voltage spikes. As the tech explained, they have a good reason for including a directive to connect the wiring entirely before inserting the fuses
. Fortunately, the repair and recalibration are only $85.00. Upon my arrival home last evening, I recieved an email
notice that the unit was enroute back to us which is pretty spectacular given that they only received it on Monday afternoon. Needless to say, that the re-installation will be done exactly as provided in the instruction manual won't be a Fluke!
Later we will be undertaking all of the tests and checks that Rick, EngNate and others have suggested and implementing the fixes and practices suggested, where appropriate. (There's no sense getting the advice of experts if one doesn't plan to use it.)
The contributors to this thread, and this entire board, have proven a valuable resource for which I am most greatful. Hopefully at some point I can offer some advice in my own area's of expertise--which clearly isn't electrics--to someone else in need and pay the courtesy I've received forward!
