yes i was monitoring danb's progress on the diesel geni , i thought the conclusion was a short at the connections.or perhaps interfearance with the 120 volt circuts . the eddy current phenominon is a little beond my understanding but if it's a factor perhaps running a coolant through the conductors would be a cure . this tubing is just 1/8" dia. the size would limit the number of turns but the current carrying capacity would be large. my multi meter is kind of lame, when measureing resistance it has .3 ohms across the leads and no way to adjust to zero . but measureing the resistance of 25', it reads .5 .hmmm? the surface would need to be coated with the proper material. i've got lots of epoxy paint but that might not do the trick.
