Again thanks for all the help. I will be performing a few more measurements this weekend to see if I can isolate the problem. I thought that the 180' of bonding wire would also serve as a ground, but since it lies mostly in sand, that may not be the case. I like the idea of a second bonding loop and an additional copper ground....
fyi, my pump, heater and swcg are all connected to the bonding wire. if i recall correctly, my autopilot says that it must be connected to a bonding wire..and my heater had a nice yellow sticker with big letters saying it had to be bonded all have water going through them and are electrical, so i wasn't going to argue
