UPDATE: So umm right after the alternator installation, I noticed that at night my high beams no longer functioned, and the standard beams would sometimes flicker or dim out. I went to advance the next day and had my charging system tested, which their little machine said it passed. I took out the headlight bulbs and the high beam filament was burned up bad. I bought some silverstars yesterday, slapped 'em in.
Today I have no regular beams, but my high beams work and my battery and brake light are coming on at random, more so at idle it seems. Again, if I'm at idle and I blip the throttle, the lights go off. What's happening here? Was the last alternator good and I have a faulty alternator harness? Who has an alternator harness they went to sell me if so?
