Re: SIX weeks and zincs are TOAST
How do you know the difference between AC and DC leakage, by looking at the zincs?
It had long been thought that AC did not cause any corrosion activity but that has been disproven, it does but it is so slow that you'd likely never notice. Leaking AC can kill you but unlikely it will cause any corrosion.
I've seen leaking DC cause propellers, shafts and rudders disappear within two weeks two weeks of an amateur "electrician" playing with his electrical system.
Galvanic corrosion is a much slower process.
The hysterical laughter you hear as you drive a way in your"new" boat ..... is the seller.
