can i also add too that when you guys do a tune up or replace your spark plug make sure to sand down the grounding point from the coils ever little bit helps ive also notice there grounding straps coming from the fuel injector those also need a good sanding too

 

ignore where the battery ground goes, look up under your car there IS a ground on the alternator. as i said i posted pics of it

 

alright man. i will take another look tomorrow.

 

here is a pic i borrowed from another member, see the pink or magenta looking wire in the lower left above the black OEM sway bar? thats the OEM alternator ground

 

havnt gotten a chance to get under my car, its been raining like crazy in cali.
but i will do it this week. my battery terminals havnt came in yet. they were supposed to come in by the 16th but i guess due to bad weather on east coast, they are lagging.

where is the factory ground to the alt grounded to? i think im going to have to ground it to the chasis.

 

dunno trace the wire back, i just grounded mine back to the battery like its supposed to be....

 

i can not for the life of me find an alternator ground. im thinking mine is bolted to the eingine and picks up its ground from engine?

i can only find TWO wires on the alt. one is the positive and the other is the one right next to the positive which is a clip on thing. i lifted the car and went underneath it and i looked near sway bar and around it and there is NO other wire. wtf?

mine is a gs300 and urs was a gs4 brian, maybe thats why?

 

doing big three on a 05 gs300 but i can NOT find the alternator ground.

anyone know where its at?!

 

The alternator doesn't have a ground. You have the output that goes to the battery and a plug that turns it on with the ignition.

I own a 99 and I know that there is a ground that connects to the bottom mounting bracket of the alternator.

What are you wanting to actually ground? You ground from your battery to your chassis and a ground from your battery to the block...

 

thanks a lot man.
im doing the big 3 and i posted a diy on the big 3 and brian (another member on here) was telling me i forgot the alt ground and he kept assuring me there is a ground on the alt. he even posted pics of an alt with a ground on the gs, but i cant find any ground on my alt. i just wanted to add a 0 gauge ground to it, just to be sure everything is good.

anyone else can chime in?

thanks jcastaneda though. makes sense since those are the only two wires i can find on the alt.

 

NP...Yeah you don't ground your alternator. I have the Big 3 done my self. I have a 1/0 power wire that runs along with the regular stock power wire from the alternator to the battery...That would be 1 of the 3...the other 2 are what I talked about in my pervious post. Good luck...let me know if you have anyother questions.

 

i did indeed....wonder why the gs430 DOES have a ground and yours wouldnt. thats fairly odd to me.

P.S. why didnt you just leave this in your other thread so you have one thread running?

 

The 430 has a ground on the alternator? Where is that located?

 

look at his OTHER thread on this i supplied a pic

 

Oh yeah...I justed looked it up. Now I know what your talking about...As I stated in my earlier post that I have mine on the lower bolt.
