    Altenators

    Seem to have the same problem when my 3B S2 fires up after a long rest,basically the car has been parked up for a long time but when it starts driving the vehicle should boost the battery up a bit so that it can start perfect after a while but no the battery keeps losing power,is it me or are the alternators rubbish?I know of another ABY S2 that has same problem?
    Looking for an S2 ABY

          I had this recently.....
          if its not battery.....check both engine and battery earth straps for corrosion at mount points...

          then try changing the voltage regualtor on the back of the alternator...then maybe try a different alternator?

              The exact problem is not clear to me.
              It does start after a long standing? Then after a short drive it doesn't anymore?

              I had (with my 3B) that it didn't start anymore after a few days of standing (even when a started it without driveng now and then).
              Turned out the emergency siren on the alarm was broken and kept drawing power from the battery!
              No power, no glory!
