Message: <blockquote data-quote="metalheadjoe" data-source="post: 8822056" data-attributes="member: 581422">The reason you have voltage on the ground terminal with the cable disconnected could be because it's a series circuit: Power goes from positive to amp to negative (according to conventional theory anyway). The difference in potential is what makes electricity flow. If you don't have a ground connected, power makes its way through the amp to the ground terminal but does not have anywhere to go from there, so the potential is between the amp's ground terminal and battery negative.I've never tested this. I'm merely theorizing.</blockquote>
