I'm having trouble w/ 1 of the big three..... the alt to pos battery post. The line seems to go from the alternator into the fuse box and I dont see it going anywhere else.
who has done the big 3 on the GS and can halp me out. Should I just bypass the fuse box and go directly from the alternator to the Positive post on my battery?
also I'm currently running off my stock amp right now but will plan on upgrading it to 130amps. Should I put a fuse inline of that "alt-battery" line? if so how much should the fuse be? 120?

well I guess I'm going to just bypass the fuse box and go directly to the battery terminal and attach an external inline fuse to the battery side.
DIY to follow in a few days once I get all my parts.

If you have a audio system or are complaining about a crap alternator then this is definitely for you! plus its a fairly simple mod... actually its very simple. w/ only 3 key points you can really maximize the efficiency of your electrical system.
The BIG 3.... Highly recommended mod by ME!
I've been skeptical about the grounding systems such as the teckis and various ebay ones b/c of such small awg but I guess I'll give it a try since ppl have been claiming left and right about smoother shifting. who knows.... for what its worth atleast it'll look pretty!![Stick Out Tongue](https://www.clublexus.com/forums/images/smilies/tongue.gif)
PS I've heard of 12.9 volt jumped to 13.9 from just 1 of the big 3. I've seen some GS engine bay's here on CL w/ the Big 3 done or atleast 1-2 of them. So I know some of you know about it.
also I'm shopping for inline fuse holders from knukoncepts.... 100a fuse AGL fuse holder. $20 for the fuse holder and $6 for the fuse. Anybody know a place where I can get some cheaper?

Get circuit breakers. That way if you overload the system and it throws, you can just switch it back instead of replacing the fuse and you don't have to worry about finding new fuses or ensuring you have a few on hand JUST IN CASE.

dont get circuit breakers.
99% of professionals dont use it, becasue when somthing CAN go wrong it WILL go wrong. and your GS and thousands of dollars of equipment are at risk.
im a big audio guy
did the whole install on my gs including full deadening of the 4 doors, back seat, whole trunk, rear deck
running big amps (depending on mood, i got alot of amps), alpine 9835, diamond hex up front with baffles, diamond m6 in back in baffles, large ported box w/2 RE 15" custom subs.
honestly if u have a gs400 all u need is a optima, i have ran ALOT of power and quite frankly the factory wiring is not very thin.
big 3 will help though. but in my opinion not that much for the gs.
maybe the gs300 would need it more though, i am not familiar with engine wiring for gs300.
if u need to know anything about gs audio hit me up. or audio in general just email me
wjcheng@ucla.edu
or soundomain page "gswill" still got lots of pics to load though, peace.

What's the difference between using the two? If you get a circuit breaker that trips isn't it the same as a fuse that burns out due to an amp load being too high?

well w/ the battery I dont want to use a CB b/c in all honesty I've seen a few CB's fail in my time in aviation... yea what a great place to see electronis fail! in a frickkin airplane! But I figure a CB has a possibility to fail or get stuck especially when you cannot protect under the hood from possible rust grime etc etc that might jam a breaker. So if it gets jammed and the battery overloads and explodes i'm pretty much SOL. Last thing I want is battery acid all up inside my hood w/ a big dented hood from the battery case.
Thanks will for the tips, I have the GS3 and the fact that I only get out 90a hot already makes me errky of the electrical system. Then I look at the wiring and they look entirely too small and flimsy. I'm not sure but I think they are 10-awg? Doing the big 3 certainly couldn't hurt it and if anything I'll have a beefier connection so I have nothing to lose especially w/ only $30 in parts.
hey buddy how much should sound deadening be for the whole car?
