FAQ:
Q: What kind of regulator does an Isuzu alternator use?
A: The alternator connections are very simple. The standard Isuzu alternator has an integral regulator which makes it even easier to wire up. Check Fig. 9 on page 6D-14 of the FSM for detailed wiring.
Q: What’s the difference between a Toyota and an Isuzu NPR?
A: I’m ok with the adapter bracket to mount the NPR, and with the wiring, but the pulley is a complete mismatch from the Toyota. Toyota is a large V belt, and the Isuzu is a dual tiny V belt….and the shaft is smaller than the Toyota shaft, so just swapping the pulley over is a bit more complicated.
Q: How many amps does a Toyota Hitachi alternator have?
A: The Toyota is a 35 amp or 40 amp externally regulated unit. The Hitachi is a 70 amp internally regulated type. I’ve got the wiring changes figured out.
Q: Where do the wires go on an alternator?
A: Basically, you have three wires going to a round connector on the back of the alternator plus a heavy black wire (B) going to the output stud also on the back of the alternator.
