Yesterday I had a strange noise comming from around the A/C clutch,
sounds like it could be a bearing going out on the pully (noise goes
away when clutch engages), now today went to run an errand and it would
not start, after finally getting it to start, would not stay running,
check engine light came on when trying to start (said no bus in
odemeter) and check gauges lit, amp gauge was around 12-13 volts, turn
on A/C goes to 9 volts. Checked with volt meter 13.84 volts w/o air,
16.64 w/air. Any Ideas? TIA 99XJ

Serpentine?
If so probably too loose to keep the alternator running enough to keep
the battery charged. Could be one of the idlers jamming and keeping
the serpentine from turning but that tends to take an awe inspiring
amount of drag and tends to leave the belt rather polished in a hurry.
