Reply to "Alternator Light always on"

Mike H.; From your wiring schematic, you have 12v going to B+ on the alternator from the battery. To have voltage coming from D+ on the alternator to D+ on the regulator, then to the amp light, you must have voltage crossing from B+ to D+ within the alternator (short/open circuit). With a voltmeter have you tested if voltage exists between B+ & D+ with the various conditions you described? You may also check for continuity between B+ & D+ with no voltage from battery. If continuity exists, then B+ & D+ are connected someway within the alternator.
