Wiring Problems
I have a new 2001 Hunter 320, and have encountered many wiring problems and substandard workmanship, so I don't think anything would surprise me on wiring now. I had the bilge pump wired to the switched side of the battery switch, and LOTS of bare wire where splices were placed. The only other thing that is wired directly to your batteries (or should be according to the prints) that you didn't mention, is the battery charger. Jumpers are placed in between banks 1, 2, & 3, and one should be removed for each bank that is installed. If they are not taken out, all your battery banks will be wired together no matter what position you battery isolation switch is in. Once you are sure that your banks are not tied together, try turning off all the breakers to isolate the drain (if you haven't already.) Then try removing the wires from the isolation switch and checking again. You can get to these by pulling the vertical panel on the inside of the settee behind the switch (two screws on the bow side). Use caution that you remove the ground wires from the batteries or the ground stud before you start pulling the hot leads or jumpers. Put the ground back on after pulling a hot, and recheck for a drain. Good luck, and let me know if you find any bare wires that I haven't found yet. Steve
