Brett, my 08 E-150 just had an alternator rebuilt. 1 of my diodes was bad & was draining my battery very slowly. It died earlier in the week & had to jump it (left my 4 ways on for an hour & a half, my fault) & i put it on my battery tender over night & is usually green in a few hours. It was yellow (charging) when i went it to start it. It started right up, but i went later in the day to a place that rebuilds alternators & they did a test. It passed the load test running & right after running. He went & grabbed the diode tester & it failed. He said it was quite common & could rebuild it within a day.
Got it installed & my scangauge showed my alternator was putting out 14.4 volts & 14.2 volts with my hi-beams, 4 ways, led flashers, defrost & blower on high.
My battery is 2 1/2 years old & i think it's 850 cca. I'm not sure, but till this past week, i really haven't had any issues.
