While on vacation last summer my alternator pulley retaining nut worked loose and I spit the pulley off in the middle of nowhere! I was able to limp it in to a little town that fortunately had a NAPA store and luckily they had a replacement alternator, but since I had lost my old pulley we had to scrounge around for a pulley that would fit to get me going again. Ever since then I have only 8-10 volts at idle but at anything above 1200 rpm it charges like it should, at around 13.8 volts. I have had the system tested twice and we can't find anything amiss other than the low voltage at idle which leads me to think that the pulley is too big and the alternator doesn't spin fast enough at low rpms. This should be a simlpe fix if that is the problem. Anyone else have some thoughts on this?
