Electrolysis When on a Mooring

I purchased a 1981 Whitby 42 last summer. I kept the boat on a mooring with almost nothing powered except for the bilge pump. My propeller hub zinc was completely consumed in 5 weeks. Any ideas how I can test for current leakage? Where should I start to look for the source? The only other odd thing I observed was that my Kiss wind generator turned very slowly all summer. In the fall I disconnected the wind generator to prepare to pull my mast and the generator turned much faster. I suspect that the generator is mis-wired. Could this be related?

This occurred within a few week span. Cause was a bare bilge pump wire in a damp bilge.

I would guess the bilge pump to be the most likely cause as well. Check all connections and re-do any iffy ones - if not all - and heat shrink. Keep all connections above the water level if possible.
