Big 3 question

[Tarball]

I think you did a good job. Just remember the big three upgrade is only beneficial if you have upgraded your alternator. Say your ALT wire is a factory 8ga or 4 ga going from a stock 100 amp ALT to a HO 240 amp ALT the charging current is going to flow better through 1/0 than the factory wire. When adding amplifiers, upgrading ur grounds is always a good idea because runing 1/0 to ur amp and having factory 4ga grounds the current is having to bottle neck down. And of course you want to choose ur power and ground wire depending on your amplifier. It doesnt make sense (money wise) to run a 1/0 power and ground to ur amp if its a 1000 watt when 4 gauge is plently sufficent. Just my .02 the big three is only for better current flow, if u have dimming lights you need to upgrade the ALT or batteries, the big three in itself wont cure that alone.

This isn't exactly true. The Big 3 can provide benefit when still using a factory alt. However, when adding an H.O. alt Big 3 is "required" because the alt will provide more amperage than the factory wires can handle.

That's a mechman 240amp in my car, it isn't stock.

Just to be clear (no pun intended), you clear coated AFTER you bolted down the ground?

Yes after everything was done.

[Gravlin216]

No fuse if it's zip tied?

I have a fuse but seen a video explaining it's recommended but not necessary if you have the wire tied up out of the way of any heat or sharp metal that could cause it to short. The run of 0gauge to the back has a fuse at the battery.

I'm just not a fan of having live wires and zero protection.

Something strange happened today though. My car is a 08 grand prix with 34k miles on it, brand new in my eyes. I've owned the car since July and haven't ran into any lights/codes or warnings. After doing the big 3 yesterday I received this warning on my DIC saying Battery Saver Activate. Huh, weird. I brought my car to Monroe and Advance. The guy at Monroe said he had the same engine and it was a sensor I need to replace. It cuts out unnecessary power like the AC to save on battery power but, the guy advance tested my battery and alt and they're perfectly fine. I guess in short, does anyone know what sensor I'm talking about, the guy at Advance was clueless when I mentioned it.

follow all of your stock wires and see if any pass-through a ring like voltage clamp if you do then that is your problem and the added wire has to also pass-though that "most times you cant fit it though"..... if you removed the stock wire than that could also be the problem if there is no clamp

I would fuse that alternator wire looks like it's rubbing on your strut tower ,

[Ron36]

That alternator wire u ran needs to go threw that stupid amp clamp sensor that goes off the battery

Parts guys are parts guys for a reason ,no offense to parts guys I love all mine at work
