I've owned the boat 4 seasons now and when I purchased it there was corrosion or clean strikes on the rudders. Since then I've cleaned and rerun some if not most of the bonding wires throughout the boat. I've replaced the old fero battery charger and since last year installed a freedom 3000 inverter. Every year the corrosion has been getting worse. When I hauled last season I had white crust around the rudder zincs and clean hits on the rudders.
This year I launched an ran the boat 1 1/2 hours to my slip tied up and left for the day. Monday I returned at lunch time And noticed that I had white crust forming around my rudder zincs and I could see primer spots on the lower section of my rudders. I unplugged the boat and retuned later in the day.
I pulled out a test probe that I purchased from boat zincs .com and went through the directions. With the boat unplugged I was well within there perameters my reading was -936 mv. I recoded my reading and checked most of the gear and through hulls including the 4 bond straps that run the length of the boat. Everything checked out perfect. I had no change in my readings everything was still at -936 mv. I plugged the boat in and still no change. After turning On and off everything in the boat I finally got a change when I started the port main. When I opened the throttle a bit the reading changed even more.
I believe the problem is the alternater. I then checked and reconnected the 3 main ground connections to that engine. The green bond wire the yellow negative to the starter and the yellow negative to the alternator. Nothing fixed the readings. So after that long winded post here's my question. Should I have the alternator rebuilt? Should I swap port and starboard and see if the problem follows? Has anyone had a similar experience? Thanks
