I don't know if this makes sense, but does your GTE have a standalone computer and if so, could the battery light be coming up but the new standalone just doesn't show it? I have never ran a standalone and I know a lot of people runs standalones on the GTE, that's if you swapped, I just don't know if it reads that warning, know what I am saying?

I am guessing you didn't read my post correctly, I want to know if you have a standalone computer in your car since you have GTE? That could be why the battery light doesn't pop up for you if the computer doesn't look for that and can I test the regulator on the alternator? is there a way to test it?

yes im running a haltech and it works fine in my car and when it was in the stock gs it worked fine im the one that installed it new in the guys car and when i got it off him i was the one that pulled it out and installed it in mine
now to test the regulator this is how i test it but you have to hold the rpms to see if it drops or go's up

I just checked my resistance. Battery to frame: .02 ohms
Battery to engine: .03-.08 ohms
Also did the regulator test and at 1500-2000 rpm's the voltage holds/increases by .1 to stay at 13.9-14.1 volts so my regulator is fine. Are those resistance numbers low enough to not see an issue there and is it looking more likely a belt issue? (Need half inch smaller)?

Do you have any clue what this could be Sphan? Did you get a shorter belt? Are you using copper terminals and have done the big 3 upgrade? Do you think this is a real issue or just the car being tricked?

If you Google "Alternator 5k RPM battery light" You'll see a bunch of people with threads on other car forums, might have to do a little digging.
My car runs find, I'm currently running a 3000w rms setup, i had to get a mechman alternator cause my OEM one fried the day i hooked up my subs. Both VSC lights and ABS light came on along with a whining sound coming out the Alternator, once i got the new mechman Alternator hooked up the whining stopped and the error lights never came back on. Subs pound harder than ever, but certain lights in my car still dim on hard bass notes with the volume cranked up.

Yes my current belt is 87.6 inches, the original belt is 88.7 inches. Only thing i could think is that it could be a bad ground, might have to test that.

Okay so you are saying even with a shorter belt you still get the battery light coming on? Maybe our system is just being tricked somehow and thinks there is a problem, I guess it really could just be a warning light that is warning us about something if it was a stock situation, not aftermarket with Mechman, you know what I am saying? What brand belt are you using? Also I just looked up the length of my belt and it is only 76.00 inches long, so how is your 87.6 inches long? Wouldn't it have extreme slack if yours was this long? Maybe measure it again, I didn't measure mine, I looked on Good year's website at their gatorback belt lengths.

My belt is just right, I couldn't go any shorter if I tried lol. It's probably cause I have a GS400 and you have a GS300. The brand of my belt is dayco, which I got at autozone. It could be the system being tricked but it's odd that it lights up right after 5k rpm, maybe the regulator cuts off power or something
