MrMeanGreen Posted January 5, 2009 Report Share Posted January 5, 2009 Sometimes (not all the time) while driving the GTP, there's interference from the speakers in relation to the engine RPMs (whirring sound and the music, very slight). This is only when the radio is on, and again, only sometimes. All grounds in the engine bay are attached and accounted for. Quote Link to comment Share on other sites More sharing options...

Guest Removed Posted January 5, 2009 Report Share Posted January 5, 2009 sounds like the alt...have someone check the diode ripple on it.. the diodes inside start to fail and it will produce a signal thru the radio newer 3.8 right? Quote Link to comment Share on other sites More sharing options...
Qtr_pndr Posted January 5, 2009 Report Share Posted January 5, 2009 All of my GM products have that same whine. Quote Link to comment Share on other sites More sharing options...
MrMeanGreen Posted January 5, 2009 Author Report Share Posted January 5, 2009 I own three and this is the first one that did it. None of the dozen GMs I've owned previously ever did it. My dad's Mustang does and did since new. I'll have the alternator tested. Yeah, '01 3800 Series II. Quote Link to comment Share on other sites More sharing options...
Benner Posted January 5, 2009 Report Share Posted January 5, 2009 Off topic somewhat, your car still running okay. Is it ticking at all? Quote Link to comment Share on other sites More sharing options...
AJ Posted January 6, 2009 Report Share Posted January 6, 2009 Is it ticking at all? yes, another one bit the dust. Quote Link to comment Share on other sites More sharing options...
MrMeanGreen Posted January 6, 2009 Author Report Share Posted January 6, 2009 This one only ticks for a few seconds after sitting a couple of days. If driven everyday it doesn't. Quote Link to comment Share on other sites More sharing options...

MrMeanGreen Posted January 6, 2009 Author Report Share Posted January 6, 2009 I just looked it up. My defroster works with all grids, and it does it with the defroster off. Quote Link to comment Share on other sites More sharing options...

MrMeanGreen Posted January 6, 2009 Author Report Share Posted January 6, 2009 I got in the trunk and checked the wiring to the amp and speakers, although the car hasn't done it in the past two days. Quote Link to comment Share on other sites More sharing options...
