3g alternator upgrade

ryanw · January 21st, 2012, 03:32 AM

I got my 130 amp 3g alternator today, im still waiting on the 4 gauge wire to come in the mail.

My plan was to wait until i had every thing before i installed it.......but i couldnt wait...lol.

So i started cutting out the old 8 gauge wire when i found that i had two 8 gauge wires running back to the solenoid. I always thought that , off the pig tail on the alternator ( 2 black wires with orange stripe) at some point merged into a single wire running to the solenoid. But under the air cleaner housing a found that one of the wires off the pig tail, was spliced into its own (all black 8 gauge wire) running to the solenoid.... is this normal, or did some one upgrade my system at some point ?

So the plan was to completly remove the old wires from the car, but i figured, ill remove one and the other ill just abandon the other, do to the fact that its intertwined in the cars harness......i dont feel like cutting open all of the protective loom.

Any ways, the alternator didnt come with a stator plug so im hoping that i can pick one up at my local auto parts store. I also need to go buy a longer top bolt and nut , because the new alternator doesnt have the threaded hole.

Does any one know what the differences in power out put is between the 2g and the 3g at idle ?

Bump....do to the fact i had two questions in my long winded thread that no one answered

Yes, and not a clue buddy

ryanw · January 21st, 2012, 12:52 PM

Yes, as in some one upgraded the system or yes,this is normal to have two 8 gauge wires

Thanks scott

Someone upgraded it.

ryanw · January 21st, 2012, 01:35 PM

Aw... thats cool, i guess some knew way back then, the weaknesses of the stock charging system and fire hazards of it,....

Ive owned this car since 1998 or 1999, so this had to have been done a long time ago

ryanw · January 21st, 2012, 10:50 PM

Hey do any auto parts stores carry the stator plug, for the 3g. I went to oriellys about an hour ago, and they didnt have it.... i ran out of time, so i couldnt check any more stores to night. But when i went on line i couldnt find it at any of them.... not sure if im calling it by the right name. I know i can get it on ebay or latemodelresto, but id hate to wait for it to get here,

FastStang91Lx · January 22nd, 2012, 02:29 AM

I doubt it, but that's just my guess. Are there local boneyards there in SD? Car-part.com will give you the closest distance of the parts that are available. If you go that route, I would just search for the alt, and then call the places that have them (which should be about any place) and see if they will cut one off a harness for you.

ryanw · January 22nd, 2012, 04:00 AM

Never mind, i should have looked at what all came in my 3g wiring kit....lol... it came with the stator plug and the longer top bolt... any ways i finished up the install about 20 min ago. Ill have to test every thing in the morning, its to late now...thanks to every one that helped..... i mean scott..lol

Glad to see you figured it out. Would of liked to help but I purchased the 1 wire kit. We just had to hook up the output cable.

cleangtvert · January 22nd, 2012, 09:21 AM

did you hook it up with the two 8g wires or did you get your 4g in ?

Its cool, i didnt need help with the install, i just was wondering about the out put power between the new and old alternator and was wondering if it was normal to have two 8 gauge wires. Scott answered the second question. This was not information i needed to have, i was just curious.

I ditched the two 8 gauge wires and installed a 4 gauge wire with mega fuse holder.

Lmao.

Well i just got in from testing, and with all the accessorys on my volt gauge only dropped a little at idle.... so every thing seems to be workng great...

With the old 2g alt the gauge almost dropped all the way
