How was the alternator tested? Removed and tested in a bench setup, or some measurements while the engine was running?hi I have a 2002 outback the brake battery and abs lights go on and off while driving the alternator tested good battery is new
After checking and re-grounding, I have used dielectric grease to help keep out moisture and corrosion. CRC grease is my favorite. I will be checking all the grounds on my new-to-me 03' Forester.Like raster said, check grounds. On my older cars, I add ground wire from the alternator case to the battery ground strap bolt.
