130amp ford alternator swap
Last Updated: Feb 24, 2015
so i ended up getting an alt. from a 95 ford windstar minivan. stock at 130amp i read a thing in another thread and off to the pickapart i was
so i grabbed the new alt, and a pigtail for the plug. the mounting points do look totally different between the ford and mazda alts if you look at them in the same aspect. now imagine flipping the ford alt upside down hmmmm, drill out the threads on the bottom, run the bottom bolt through there. then run a long bolt through the top section with a nut on one side for the tensioner arm.
mazda 55amp left, ford 130amp right
notice the thick bottom on the ford one
can just barely see the 130A in the middle
v belt pulley i grabbed from an old ford truck alt will i was at pickapart
new pulley (only need a single, but this was all i could find, supposedly the mazda one works on these)
ground off about 3/8" of material so the belt would line up with the inner pulley
i had to grind off about a 1/4" from the pulley side of the mount for the top
make sure you connect the middle wire from the plug over to the field. screwed this up the first time following the other directions, didn't work. works good now
i made a little splice wire to run the choke for now on 12v+, not the proper way to do it, but it'll do for now
heres a wiring diagram for this style of alt
im also running this big mother of a battery so i'll never have a shortage of power. plus im running 2 gigantic compressors for my air system and now the lights don't even dim when they come on

Very handy how-to!!! I have one of these laying in a box around here so I will probably do this!
JUST to be clear...as the pic is blurry.... on this part:
"make sure you connect the middle wire from the plug over to the field. screwed this up the first time following the other directions, didn't work. works good now "
you ran the middle wire from the FORD 3 wire plug to the small single wire plug just next to it?
NOTE ON PULLEY.......I got an alt off a 2001ish Taurus and the Mazda pulley is 1. Too small and 2. requires some sort of spacer to lift it off the alternator. I have drilled out my pulley holes BUT am havin issues finding a spacer.
have the alt wiring and accessories. question is does any one know how to take the internal regulator out? i want to use an external adjustable regulator.
i used to work for an alfternator/starter rebuild shop and in this pic
the white box at the bottom of the alternator that the pigtail plugs into is also the regulator... where is says motorcraft
thought someone may find these parts useful first one wai part num f794bnc a to b circuit conversion adapter. 2nd transpo external voltage regulator part num 91102r remote adjustable voltage regulator 12 to 18 volts.
this is so easy i cant believe this has not been done many times over. better than the one wire gm any day.also you can use the mazda pully and there was a spacer on the mazda pully that i used worked fine.
