Mopar1973Man 5,581 5 Vehicles Posted September 13, 2010 That points to the issue that your alternator might have a bad diode creating AC waveform. What you doing is covering up the AC noise using tin foil. So I would suggest you have the alternator bench tested for diode function. Because even 1 bad diode could leak AC into the power.
