Lol the check engine lights been on there since I got a brand new engine put on its dumb...

Another battery?? I was hoping just 1/0 in big 3 will cure this

so what voltage does it actually drop to?

 

[revrider1 5,000+ posts]

Um, 2400+watts on one battery is a bit much IMO...

Yeah, who knows exactly how accurate that gauge is...

 

[WOT]

lol, do you even no what your dropping to?

It dipping down that 1/4" might be 12.5+ still

Get a DMM on your battery while playing to see what youre dipping to before doing any upgrades

But yes the big 3 will definetely help and is worth the $20

Idk what its dropping down to. Which battery should I put the DMM on? hood or back battery?

 

[revrider1 5,000+ posts]

Big 3 wont hurt no matter what. Id do that anyways...

That's not that much of a drop. ~11V is when you get to the big marker towards the left...I have an '04 dodge as well, but with a 160amp stock alt...what size is yours? And yes, big three will help.

 

[Bobby322 10+ year member]

Well it kinda stays put at that level. Idk what size my alt is, whatever is stock on it with a 4.7L v8. I know the big 3 will help, i wanna know if it will stop it from happening
