Why is my voltage drop so awful?

LOL... no you didn't. Your friend had a battery that defied the laws of physics? HA... phial.

Yes, I did. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Your first sentence is precisely why you should have a dedicated run of 1/0 for the ground. A 20' run of 1/0 is much more conductive than the body of your vehicle.

I'm sure it would help slightly, but not correct a drop as severe as 1v.

HAHAHAHA. Since you have magical abilities and know everything... why can't you fix your problem?

I have grounded to the bare frame before and had terrible voltage drops. Moved my ground to a point on the body and voltage issues resolved.

Point being that just because you are grounded to the frame does not mean that is the best place. It depends on where your front bat is also grounded to. Try to make all of your components ground to the same place, instead of the multiple locations mentioned above. Dedicated runs would probably be best

Since you have your own website and everything...why are you here? Oh, that's right...

I know what I saw, now go troll elsewhere.

Obviously because people are stubborn. They'd rather stay on this junk site and complain about it than try out one that has none of the problems this one has. You didn't see that because it's not possible. You're not fooling anyone.

Are you stupid? I am one of the only people here that knows what he's talking about. I provide quality information to draw people to MY site.

You REALLY don't get it, do you?

That you're not anywhere close to as smart as you think you are? Nah I get it.

if you're losing ~1v between the battery and the amp, it's right there. either the wire, connection, or connectors on that run. check all that apply to the power and grounds. have you tried to use a different run of wire? check resistance of the wire you are using?

Fix that bullshit ground at the back battery and I bet your voltage will be up. Also, I recall you saying that because the battery in the back rest the same as the battery in the front, that they must be grounded right. Are you serious? Batteries will rest at 12.6 without being grounded at all.

And Ecrack is trying to help you and from what I can tell, he knows what he's talking about, unlike you.

Since you STILL aren't getting it, let me break it down for you:

I asked:

You replied:

Yet, here you are on CA.com, complaining about CA.com.

This makes sense. The wire goes straight from the battery to the distro, and by the time it gets to the distro the voltage is already hampered. Could it possibly be the ring terminal, since I've soldered and unsoldered them to reuse them multiple times now? I don't have any remaining wire, but I will try to measure the resistance, as you suggested.

Someone in this thread mentioned that voltage should be consistent throughout the entire system, so even at the amp, which is what is draining the current, I should see the same voltage as the batteries?

Before you tell me I don't know what I'm talking about, maybe you should read the thread. I regrounded my battery directly to the frame, and it did not help AT ALL.

it could be the terminals if they aren't getting a good bite. could be a bad wire.

and the voltage should be VERY similar at each battery, component, and anywhere else you could measure it (alt,distros,fuses,etc). where is the front battery grounded at? i'm leanin towards connection/wire problem.

also, are you measuring on the battery side of the distro, or the amp side? if the amp side, it could also be the distro causing resistance. (measure both sides and see if there is a difference)
