I've search high and low and can't find an answer to this. Ive swapped voltage regulators and alternators and it's the same. No charge, 12.2 or whatever the charge left in the battery is, and I've used more than one. I've got a battery light on flickery, it almost goes out when revved but not quite. Tests I've found on here say the two larger blades on the alternator are battery power and the smaller should be one volt less key on not running, nothing key off, I've got 1.3v key off 2.3 key on. Then I have full proper charge voltage 14.4 at that terminal with it running. Could it be another bad voltage regulator?
