January 4, 201115 yr Author Hey, the forums are back up! lol... Okay, I guess I misunderstood that somewhat. Either way, I believe I'm just going to go ahead and replace that alt. Figured I'd go with a lifetime warranty one from O'Reilly and call it good. Hopefully the voltage is right though, which I know is not always the case for some reason. Is it supposed to be 13.5V or 14V?
January 4, 201115 yr A good alternator should be able to maintain the output voltage between 13.5 and 14.8 volts while the engine is running around 1500 RPM and there is a good load on the electrical system.
May 25, 201114 yr Author Sorry for resurrecting this old thread, but there have been new developments where I thought this issue was resolved. Initially I thought I was having an unrelated problem (so I started a new thread) but as it turned out the alternator I had replaced went bad too. The story continues in this thread... http://www.ultimatesubaru.org/forum/showthread.php?p=1019447
