Yesterday i noticed that the Hicas light was coming on when driving prior to this the battery light was coming on until i gave her a rev and drove her for a bit, then when i turned her off she wouldnt start i managed to get her jump started and just got her home with the car cutting in and out, this morning i went to start her and started fine and i drove her for a bit and she was still fine then the battery light and hicas light started again, is this the alternator??
