I really think this tread got lost in the do it this way no this way shit that was going on in the first like 8 pages. That previous page was probably the most informative besides the first page. Looks like mike got the thread back on track....as usual

I used an S13 alt. and the 710 v pulley swapped over. Not perfectly... I had to make up a spacer/washer so the pulley wouldn't rub the alt. case, but it's been in an running for a couple of summers now. Make sure the belt is snug when charging... it takes a bit of torque to turn them and the belt will squeal. If a D21 alt is available I guess that would be easier.

and did you get the plug that goes into the alt out of a truck from the junk yard?

. I'm using the plug off of a 125 amp quest alternator wired as datsun mike shows above minus the t connector,I soldered and heat shrinked it to the the cars harness.the plugs are the same other than wire gauge which I don't see as an issue sense they are not carring high amprage.

My son (FAT510) replaced his 79 internally regulated with a 92/93 pathy alternator ( looks exactly like the one you pictured) and it hooked up exactly like the original one did,, meaning the little wire went to dash light and big wire went directly to battery,,, in a round-about way of course,,  but still.

 

(edit) his was single V grove belt style

 

The big question is what in the hell is on your shorts man?

so from what your saying i can run it like icehouse described or threw the t plug like mike describedi think ill bolt it up and make temporary connections to see if it works then finalize everything when i have it how i want it

I have a 90 amp alt on my 8o kc with an L20B. I used the v6 alt off of a d21 4x4. Easy to adapt pig tail if you save plug-end from donor. I 'machined' the water outlet flange  with a 3" Craftsman belt sander. Also cut a small clearance 'window' on top of alt housing..tight quarters but it fits. Paid $30 for a used alternator...better than new or rebuilt. EASY!! Fast..even the first time. WORKS!! CHEAP!P1050188.jpgP1050189.jpgP1050191.jpgP1050190.jpgP1050210.jpg

Pathfinder alternator on a L-18.

Bottom mount.

The Pathfinder alternator has 10MM holes on the bottom mount,  I got 8MM to 10MM sleeves in the holes, and used the mount's 8MM nuts. 

If you can drill a straight 10MM hole through the mount, you could use the long 10 MM bolt off the Pathfinder you got the alternator off of.
