I had a overheat problem in my wiring and would like to know a few things before I repair it.<br />1. I take it that the AC and the DC system are two separate systems. Does this include the grounds? Right now there is a common buss bar where all of the AC grounds terminate but there is one heavy ground wire that goes from this bar to the engines. Is this correct or are we mixing the two systems?<br />2. Does the ground for the genny goes to the AC or DC grounds? <br />3. I have this device called a "zinc saver" and there are no instructions on how to wire it. There is a terminal on both side of this device. I was told that the AC ground goes on one side and the DC ground on the other. Does anyone know if this is true and if so does it matter which side the AC goes to?
