Scottfab,
I stand corrected. It has been a while since I graduated - yes, it is microfarad. My first enclounter w/ alternator while was in 1980 when I installed Mitsubishi electronic head unit w/ 4 channel, 100 W Mitsubishi amp in my first Corvette - 1979 L48 car w/ mighty 185 horses. I rewired hi-fi unit a dozen times over in 12 months period trying to rid the system w/ the whine. Eventually, one of the installers I was talking to suggested running a capacitor. This solved my issue. I ran into a same problem w/ my 94 Z. All I know is it worked. $5 and 10 minutes is worth a try. Ground loop isolators solved my popping issue as well. |

Update: It needed ground loop isolators. Once those were placed inline, it took care of all the popping issues as well as alternator whine. It seems like a kludge to me, but the system sounds good now. Thanks for all the ideas and help!

AND they would have actually plugged it into a Bose system and found the noise issues. It comes as no surprise to me that just running a single ended source into a differential amp input would have issues. Apparently this is what the harness tries to do. Pretty fly-by-night if you ask me.

And alternator whine is back. It came back last night while just driving around. It doesn't pop when turning on or off though. Can these ground loop isolators go bad? I'm worried the alternator is on its way out but hoping for just needing to replace those isolators.
