bonding system somewhere. I used your meter and came up with some interesting readings. The battery negative, eng. block and prop shaft were all between .029 and .054 (in range). Everything else which includes all the thru hulls and cutless bearing housing were between .856 and .870 mA (out of range). That's pretty close to even but all out of the protected range. I'm going to have to track down the open as soon as I get back into the condo. I didn't log the readings I took 7 or 8 years ago and, of course, I lost the paper I had them written on. I'm kicking myself for not transferring them into the log like I should have. I know the damn paper is around somewhere within 38 feet of me but you know how that goes. I'd like to compare the two and see if something shows up which might help locate the problem.
