Default 3G alternator upgrade

Been looking in j-yard for 3G alternator. Got one in j-yard for 17 dollars. Also got a alternator harness out of a 97 Ford F-150 with a v-6 Has the 175 amp fuse need and larger cable. The fuse came with a holder so reason I chose that setup. Had to remove some of the alternator mount and mount 3G. Will need a new bolt for top. Remove old wiring. It looks like a lot but it funnels down to 1 wire to battery at starter solinois and one small green with stripe. Install new wire harness big to solinoid and the green with stripe to green with stripe. Now lights don't dim when ac is on and turn fan on high. Will have to upload some pictures. Maurice

THATS A GREAT CONVERSION WELDER DUDE. I think its 130 amps. What kind of vehicle did it come from?? My alternator guy does not know what i am talking about. I dont have the part number. If i ask for a 3G at the auto parts store they ask year model and engine. Did it take a lot of grinding on the bracket?? I Installed a 130 amp delco unit in my car and it was a real JOB. Yours sounds much better. Post up some KODAKS and lets see your handy work. I know its clean and cool. You are a real craftsman dude. Cant wait to see the instillation TOM

Tom, ask the parts counter guy for an alternator for a 94 or 95 Mustang GT. It's the 130 AMP 3g with the mounting tabs clocked very close to the original alternator.

I had to clearance the bottom alternator bracket (just above the power steering pump), and I McGuyver'ed the upper bracket bolt hole. I took a 1/4" pipe nipple and threaded it into the hole until it was flush on the other side, then cut it off flush with the front. I had to ream the inside of the newly bushed hole with a drill bit, but now it takes a 3/8" bolt with no slop.

For the wiring, I ran 4ga. wire from the alternator to the starter solenoid with a 100 amp slow blow fuse mounted on the strut tower. That got rid of the fusible link and light gauge charging wire.

It took 3 or 4 hours to do the whole thing start to finish once I had all of the parts lined up.

Mine came from a v-6 Thunderbird.
Cold Air Induction Install Link says cold air induction but it is on the 3g
One of the best writeups. For the 2.3 use the 7" spacing.
3G Interchange Facts. If you're thinking 3G, read here. - Four Eyed Forums
They have some good writeup on the alternator and differences etc.

mine was off a 97 taurus, i took the old large 2g harness tucked it back into the harness and wrapped it with tape so it was hidden, then spliced the small harness white/black wire into the 3g single white wire. the small 2g harness plugs right in and i had to grind down the alt. bracket to fit the larger alternator. i found a 4 gauge FACTORY alt wire from a police crown vic, and used a 12 volt 80a breaker. after about a year the 3g failed, so i just tossed on the old 2g cause i didn't remove any of the original components, fit right back in.

on oriellys website after you click onto a part there is a compatibility tab that will show other vehicles that particular part will fit.

The big red one on the right feeds the old school Yamaha amp under the driver's seat. The other is black with red heat shrink covering the connector and without going down to the car (which I plan to do in an hour or two), I can't really remember.

cool man thanks, im doing the conversion and dont want to miss anything. Hey is that 100 amp fuse big enough to protect the car from overcurrent even when youre idleing @ 3000+ rpms? or is it the voltage regulator that does that? cos i have a 120 amp fuse im gonna put in but i didnt kno if it was big enough

I had the same question when I did mine. Here again I don't remember the particulars, but it had to do with constant current an inrush current. It seems weird to use a 100 amp fuse behind a 120amp alternator, but if you look at the data sheet for the fuse, it's a slow blow fuse that pops pretty quick above 120amps.

Thought I'd jump in on the fun. Here's my contribution to a 3G wiring conversion.
