Has anyone done the big 3 wire upgrade, if so did it help with the electrical system and how long did it approximately take to do? thanks. I want to see if it is even worth while to spend the money on to do.

 

i thought about getting some welding wire and doing this. it shouldnt take any more than 30 minutes to do and i dont see why it wouldnt help.

 

You dont need.

Its always good to do, but I have yet to see any positive results from it.

 

Do you think this would help with my amp draw from my 05 efans at idle when they both kick on high?

 

yes, i still run a 102 amp alt with all kinds of amp draw and all i did was upgrade my alt wire and i have no issues

you can put the largest alt on your ride but if the cable cant carry the load it wont do nothing but cause a fire

 

Interested in this as well. My voltage needle drops whenever my subs hit.

Does anybody know the Gauge for each wire?

 

upgrade to 4guage if you can and youll be fine or if you have 2gauge but minumum i would use is 4 but like said before what i used was actually the ALT wire off a TB i do believe and i have no issues what so ever

 

4 gauge correct? I went to Lowes and saw some 4 gauge and it was HUGE Thats some big damn wire for an Alt. Just upgrade the red wire from the alt to the battery or should I do the ground as well?

 

Doesn't the B+ wire to the alternator also serve as a fusible link to protect the entire electrical system in the case of an overcharging condition or internal short in the alternator?

I'm also curious as to who has done this mod and ended up with radio interference as a result. I'm not trying to be negative, just want to cover all the bases

 

There is a sticky about the big 3 upgrade over at fullsize chevy... some people even go bigger than 4 ga and run some 0 ga or welding wire hahah... im gonna do it after i get an optima battery... anyone know how long the stock batt should be ok in my truck? cause its still there.. 4 years old...
