Ok, this is kind of a complex situation. Ill do my best to discribe this ****. Firstly, for the last week or 2, my radio will come on and go off randomly, in no certain pattern. But it works fine with the engine off. Secondly, my windows, fan motor and headlights all pulse the my engines idle (it has an erratic(sp?) idle and jumps from 1000-1500rpm). When I roll up the windows you can hear them speed up and slow down, and overall they are much weaker and slower than ussual. Fan motor also makes the pulse noise, along with headlights dimming and brightening at idle. When Im driving at higher rpms it does fine. Im thinking these problems are both related to one another. Im thinking its an alternator or ground problem. What does this sound like to you? Its been like this for over a week and my battery still charges, so it makes it even harder to figure out. Ive never been good with electrical system trouble shooting. Thanks in advance

87' T2 if that makes any difference to anyone
