and the new iraggi one with only two wires

also, in his paperwork it says something about upgrading ground wire from alt also. exact words here- The upgraded ground will go from the back side of the alternator housing (case) to the frame of the vehicle. Do not put this ground from the alternator to the body or engine block. Be sure it is on the FRAME of the vehicle. If your new iraggi alternator does not have a threaded hole on the back of the housing to connect the upgraded ground wire ring terminal to, use the mounting ear bolt that is closest to the back of the alternator housing. Then using this same wire size, upgrade the ground from your battery to the same location on the frame.

Not sure, as I haven't messed with many alts, But I would think that the bolt sticking out the back would be a ground, it would be dangerous for it to be a positive with no cover/cap on top of it.

None the less, Go ahead and hook the ground up, and the pos run to the batt.

Trace the wires back (from the stock alt) and see what leads to what

thansk for the help thus far, and now that u say it, that does make sense for it to not be a positive.

Yeah, I originally assumed it was positive, but I doubt that... would be crazy unsafe

anyone else?

aftr lookin at the alt after further inspection thus far, it says attach hot wire to alternator charging post, which i wud guess is that threaded rod. there is a plastic spacer in between that and where the terminal will rest as u can see in the pic.

wow, I'd go crazy with some liquid elec tape all over that thing

I ust bought one from him a few months ago.All I had to do was ground one of those wires and run the other to my field terminal on my external regulator.Your factory plug should plug right in though.And the ground I just used a ring terminal and sandwiched it between the alt and the block when bolting it down.View attachment 26500236View attachment 26500237

Here's a couple pics

could maybe you explain just a little more clear, not to be mean, but im not that mechanically inclined. so that bolt you have in that first picture you posted, is that the ground or thebattery power?

That first pic is his ground.

I'd say that it is the post, hook that to the battery.
