[QUOTE="helotaxi, post: 3476748, member: 550915"] It was an article by Dave Nousaine and is based on flawed theory. He's using a tape pickup to "detect noise." All he is "detecting" is the flow of current, not noise. Of course the flow of current is highest at the battery neg, it all has to go through there. The battery is still doing its filtering job; it's still in the circuit and still wired in parallel. In the same article he talks about using the tape head to "find a quiet ground" on the chassis. All you'll find by doing this is find a shitty ground. If there is no current flowing in that part of the chassis, there's a reason: it's not well connected to ground either because the welds holding that panel in place aren't very conductive or the matrix of the metal is flawed effectively isolating that area with a high resistance fault in the metal.
