if one of the eight diodes is shorted, the fuse blows. your alternator has a Y stator with the neutral point used. check the field coil for resistance. also, check your field coil for current draw while out of the alternator. to do this, connect an ammeter in series with a fused wire. the fuse must be the same amperage rating that of the fuse that goes to the field coil. if the fuse blows, the field coil may be shorted. when you do this procedure, make it quick to prevent polarizing the field coil rotor.
as posted on one of my replies, the 15 amp fuse connected to the charging circuits blows. that could be it.

field coil has zero ohms on all three terminals. no short to ground (or core).

regarding the field coil current draw test, i dont have an ammeter for now. not sure if the 10amps on my dmm will withstand the draw. i think i'll pass on this. baka mamickey mouse ko pa itong alternator.
