Was driving this weekend and noticed that I wasn't running at 14v, rather around 12 ish. I knew I had an old battery, a 2007 I kept for a jump batter for the mower when it wasn't charging so I didn't think much about it. Seems that my alternator had died and run the battery dead. I had to get dad to come and jump me since I was only 3 miles from home when it quit. I guess its a good thing AAA pays for a battery replacement. I got my A/C gauges and vacuum pump in today but did not have time to diagnose the A/C which is not very cold at idle and on the cheap gauge had about 80 psi on the low side. My guess is if I change the compressor(which seems to run non stop with A/C on), the orfice tube, and the drier, vacuum it down and check for leaks, then another hour or two, that it will take care of my A/C problem.
