3G alternator wiring....

[88grandmarq]

what's the best and least expensive way to wire in a 3G alternator? Already have a known working alternator.

pictures are helpful, if you have them.

Whats it going into?
If its an existing 2G installation, regulator plug plugs right in. Existing output wires + 10guage wire to battery positive using a fuse. White wire from the "big" plug gets a sense connector spliced on (single terminal) and plugs into the 3G sense plug/spade terminal.

A 130-amp charge cable from a 90's explorer just barely reaches the + battery terminal if you don't want it to look pretty, and it has two 65-amp fuse links in it already. Then you can ditch the factory charge wire totally, if you wire it to self-sense. If the original regulator plug doesn't work, grab one from any 3G donor vehicle. All you have to wire into the car's wiring is the green wire for the battery light, if you make it self-sense (hook the yellow wire to the alternators output stud). In the factory wiring, the yellow sense wire goes to the starter solenoid stud with the original charge wires, so you loose it if you remove those wires. This throws some people off who use the original regulator plug.

Man, I should really get a pic of this thing...

Get it off of a 97+ F150 It will be on the firewall on the passenger side. it has the 130amp mega fuse, and a little aux. fuse on the side of it. It has all the hookups to just directly bolt it onto the alternator, all you need is to get a cable to go from the fuse block to the solenoid, We got approx 20+ feet of 4 ga. from a van with a elec. wheelchair lift, and use that for all of the conversions that we do.

So far we have done three with this kind of setup; my merc, my cousins merc, my dads mark vii, and soon a freinds vic.

It works, and looks perfect, just like factory.

its on an 86 CP wagon. going from factory 2G to a 3G. when you say splice the white wire from the big plug on a single termnial, what do you mean? pictures are helpful.

thanks Alex

Yes, you should get some piktars.

Found one I posted in another thread a long time ago, theyre off of 98+ F150s'.
I also forgot I installed one on my truck, so that makes 4 with this setup so far, and another on the way.

the few trucks with that setup I find always have those cables all hacked up... that is definitely the uber-OE charge cable to use...!

use your original connector and splice the black white wire to the 3g stator. cut out the old red black charge cables but leave the connector together on the drivers side (tape or wire nut the two wires you cut off at connector). run a charge cable minimum of 6 gauge with 175 amp fuse bolted to the starter solenoid.

piece of cake

here are the threads and pics that helped me.

the white black wire is the one you move over to the 3g and you cut off the red black wires up at the connector on drivers side. tape them off but leave the connector plugged in for the other wires that runs through it.

You dont need to do anything with the original white/black wire... but that is one way to do it. The simple way is to just run the middle wire from the 3-wire regulator plug right to the stator terminal, like it is in factory 3G wiring.

I picked up a couple 3.0 Taurus alts, they have a TWO wire cn, did I screw up? Can they be utilized?Thanks....

Hmmm... if they came from new-new Taurus', you mave have gotten 4G alts.
If they look like they will fit, try it out! They may have re-designed them to make the stator connection internal.

the simple way? its the same wire and it doesn't get any simpler.

[85crownHPP]

true, the effort is about the same. How it looks in the end is the main difference I guess
