89-93 v6 70 amp alt to 94+ v6 130 amp alt swap article along with the big 3 upgrade
okay guys, i finally got around to it, so here goes,.
this is the beginning of my series of pics depicting a swap to a later model 1994+ v6 130 amp alternator in my 1992 thunderbird that was originally equipped with a wimpy 70 amp alt, we also upraded the Big 3 which is supposed to help with the dimming of the headlights with high wattage audio systems. props go out to my friend oscar, aka guitar maestro, who helped me wire the whole thing and donated not only his expertise, but also alot of 4 ga wire. here it is in it's normal habitat. we used redthunder's alt for the swap into sesshomaru.
here's the difference between the two alts, the wimpy early model 89-93 v6 70 amp alt is on the left, the better later model 94+ v6 130 amp alt is on the right.
here is the early (89-93) alt wiring harness.
here is the 94 alt wiring harness, notice the difference.
here is the extension piece that must be added to the bracket so the later model alt will bolt up to the early model mount.
here is the top view of the extension, this was made with a piece of heatshield that i had laying around.
here is the mod you have to do to the early alt harness to plug in the newer alt. you just cut the white with black stripe wire and install a small female spade terminal on the wire and plug it into the newer alt. you do not use the rest of this connector
here's how you plug it in.
this is the 5/16's by 6" bolt along with washers that were used on the bottom hole of the alternator.
here's where it goes, you may or may not need it depending on if the original bolt will fit through the hole on the alternator. if it doesn't you will also need the nut to go along with it. but according to oscar he didn't have to do it on his early model cougar, but we had to on my bird though. be sure to use threadlocker blue on all of the bolts to keep them from vibrating loose.
okay that's it to the alt upgrade, big three is in the next post.
