Thank you - I first replaced the small alternator cable (D+) without the large one (B+)
and did not notice any significant current draw. I then replaced the large alt cable (B+) as well, and did not notice any large current draw. I did the magnetic test and did not feel any attraction. I then inserted the ignition key and turn to position 2 (but did not attempt to start the car) to look at warnings and hear buzzing from relays etc. At this point the alt is energized (by the magnet test). I then turned off the ignition, withdrew the key, but found the alternator still energized. So this is presumably the sink for the current. I have already replaced the regulator in the alternator having suspected a charging problem when I first had flat battery. Where should I go from here?
p.s. have ordered a current probe. I inspected C2 in the footwell and did not find any issues there. Where is the alternator controller if it's not the alternator itself?
thnx
