I just drove up to Fargo yesterday for the Nintendo Fusion concert featuring Finger Eleven, Revis, Cold and Evanescence (good music, short 40 minute performance with bad lip syncing from Amy Lee). Round trip was about 265 miles and I averaged around 75 mph and I got 21 mpg, but that was driving with a dead alternator on the way back (stopped halfway home and bought a new battery to get me home to a spare alternator which went bad less than 10 miutes after I put it on)
Thats 4 alternators in 20,000 miles -pisses me off.
Anyhow, I have got to get some sleep so I can go to town on my car tomorrow looking for bad grounds or whatever is causing the alternators go poopie. I already put a new battery ground cable harness in today (while I was swapping the alternator) as the old one had about 4 inches of bare wires right under the ECM and coils.
