I first replaced my battery last week after doing a jump on a friend's van. (Stupidly, I had done it with both cables on my battery and not the negative grounded on the chasis, as I knew was better, yet tried that way after it didn't seem to be charging the van).
It seemed before and after the new battery was installed that the alternator worked- the lights would get brighter with higher rpm like they ought to normally.
Then, after about 300 miles, while driving, the lights get way dim and it decides to just die. My gf gives me a jump, three times to get home (the correct way), the last time we figured out that we had to charge it 30 min to get home that last 10 miles.
So, the battery is brand new Autolite from Kragen (it was free, under warranty). I am now wondering that this incorrect jump I performed last week has fried my alternator and/or voltage regulator (and why did it take so long to come about?). I am also wondering if there may be other possible causes or effects from this same issue- like if I replace the alternator will I expect to see more problems down the line with other electrical parts? Certainly this new battery is ok still, no? Could this be a fuse or fuse link instead of the alternator?
Also- does the Legacy have a generator AND an alternator? If so, could the problem be in the generator?
Thanks in advance for any help!
