these are all using big gauge wiring (8awg,4awg, or even 0awg)
1, connect wire from positive on the alternator too positive on the battery
2,connect wire from battery negative to chassis
3, Engine ground to chassis
It just helps the electricity flow better, but its kinda pointless if you dont have a system

I could be wrong but,I think I used 10-12 feet.
It's been awhile.
The - to the engine is the same as the factory -wire.
And the - to the chassis is the factory -wire too by the radiator support area.
I did not remove the factory wire just doubled them with 0 gauge on top and big connects.

2 RF 300-1
But Im running at 12 amps when im not moving and my stereo is not in right now (I take it out in the winter) but its low because I have an underdrive crank pulley and I think I need a new alt

btw people have run much larger amps with out ever doing the big three (i got a 500w alpine, with out ever touching the cables or the alternator (still origional at 109K), and i also have a underdrive pulley installed also, and i do play my stereo at idle no problem

without anything else on, but just the headlights/running lights on (at the battery itself???, i would also check it at the alternater terminal itself also first, to make sure there is not too much resistance in the wiring)
then i would switch out the underdrive pulley as the next step to see if it comes back normal (which it might)
but as long as the wiring itself is still good, i would say the alternater itself is bad (still should be putting out more then that even with a underdrive pulley on there)

It was going down to just above 13 before I put the underdrive pulley in, so I think its the alt too
Im still doing the big three just ordered the parts. I will see what that does and then if it doesnt go to mid 13s then I will do the alt. but I wanted to do the big three anways because My amps are hungry (Stupid RF)
But I am running HID fogs as well as HID headlights not sure how much power that is using

BTW I love that DIY it was exactly what is was looking for and the price on the wiring was awesome too (I pay $4 a foot for 0 awg here)thanks Im retarted when it comes to searching and I search both TL and CL side and Then I got it through the audio side and through a link on another post

What is the purpose of this? Correct me if I'm wrong but the alternator already has a regulator on it, and when that fuse blows your battery is gonna stop charging. So unless you're checking that fuse every time you get in and out of the car odds are you're gonna blow it without knowing it and wind up with a dead battery.

Its incase the power wire comes lose and grounds out it could cause a fire thats the only reason
there should be no other reason the fuse would blow assuming you have a large fuse 250amps the alt would never put out that much though

and still better with a discharged battery , then a burned down car, and anyways the charge light should also be on, if the fuse does happen to blow

No not im not arguing that the loads that come stock are crazy. But what I find really weird is when I click the ligths once so just back lights and side markers(which are custom leds 24 to be exact so hardly any power and all my interior lights are leds as well) it really dips
Btw as soon as I go its around 14.2

Whats up with RDX owners?

IIRC 12amps is correct for idle. You need to bring it up to around 3k rpm to see 14.

I did a quick search and you should be at 13.7-15.8 at idle with nothing on. But it does vary with temperatures.

How would 15amps blow out our electronics when at higher rpms the alternator sees 100+?
