gm 3 wire alternator swap for 1st gen?
« on: Aug 01, 2013, 02:38:17 AM »
After looking for hours on end... Can Somebody Please PLEASE!  Direct me on how to swap in a gm 3 wire alternator into my 1st gen. I want the charge light to work! And need to know what wires to tap into, it has the 6 wire, (45 amp alt.), voltage regulator plug. Yes I know about the bracket I need but Cannot find exactly which wires to tie into. Thx fellas!
I blame the automatic transmission for the wussification of America
If Its got tits tires or electronics, your gonna have problems
I drive a jeep cuz toyota doesn't make strollers

I did a similar swap into my first gen SR5 but with a GM one wire, everything works great. Trail Gear sells a mounting bracket that makes the swap easy.

 :beer: :beer: :beer: :beer:....later 
Update actually installed a cs130 gm 3 wire.
Charge Light and Brake Light (its CA model '81 so its actually the "Sensor" instead) light wont go out, the GM alternator is charging the system. (4ga wire - junction block -4ga-125a fuse-battery) also a 4ga ground wire directly from alt case battery.the original large white power wire is on the junction, sense wire is hooked up properly.
only the Red ignition wire will excite the alternator on both alt termnials L  or  I/F.
My charge wire doesnt give the 12v to excite the alt.  like the cs 130s setups say. Toyota runs to the 12v+ from alternator to a ground path via charge light relay.
if i hook up my yellow charge wire to L, my red swicthed ignition to I/F the alternator charges but trips  both the charge and sensor light. Like previously with adventures of bad toyota alternators and ext. regulators.
im thinking to wire the charge light and senor light in series off the ignition circuit to the L terminal. And hooking my switcged ignition wire to the I/F terminal bypassing all the toyota curcuits, just hope my gauage cluster can handle severing my charge and sensor light.
Unless theres insight on this
UPDATE: deleted charge relay, connected yellow and yellow/white wires together running power from the lights directly to alternator.
Toyota used power from alternator to trip relay for the lights on externally regulated alternators. Gm uses the regulator to shut off the ground once the alternator is energized. Interupting the power flow from the charge light
