Hmm, the AC Delco 105 amp alternator lasted three and a half years with the battery before it went. This would be the second Napa Raylock rebuilt 140 amp to die in 4 months.
It did it again this morning, lasted for a couple minutes, voltage jumped up to 14.5 for about 30 seconds, then back down to 11.5 for several minutes, then back up to 14.8 (about a volt higher than normal
) and slowly went down over my 45 mile trip to work, but still never got within 2 tenths of where it normally is...
I don't quite get it.
