I am in the process of upgrading my charging system to support the installation of a FAST EZ-EFI 2.0 system. I purchased an AR Engineering bracket kit to mount a Denso alternator and I am doing the bulkhead connector bypass with an 8 gauge charging wire and 12 gauge fusible link. Yesterday I came across this Denso altenator mounted in a mid-80's Jeep. It has the double V-belt pulley I need and is rated at 75 amps, which sounds about right, but I'm not sure how to wire it. All the info I find on the web refers to Denso alternators with a charging wire and an additional 3 wire plug. Will this alternator work with my charging system and electronic external voltage regulator? And if so, can anyone tell me how to wire it up?

Some see the glass as half empty, some see the glass as half full. I just drink straight out of the bottle.

I don't think that will work with a voltage regulator. I'm pretty sure these are internally regulated.

The Denso kits I sell use an internally regulated Toyota alternator.

The alternator in your picture is a factory style alternator which uses an external voltage regulator. So you wire it up like a factory alternator. Those big Denso alternators came on lots of cars and trucks in the 80's so it shouldn't be too hard to find a wiring diagram in a FSM.

2 small terminals wire up just like the older stuff, just need ring terminals on the wires vs push on.

definitely externally regulated
