2G 2025 battery relocation questions

[Bedicine]

Hello

As a lot of people know I’ve been having ongoing issues with the electrical in my 95 gsx. I’m going to try a used oem alternator instead of going the rebuilt route again for the 7th time.

Before this I want to make sure my wiring is proper with the battery in the trunk now. I’ve seen the merged thread but a lot of the photos are dead links and there’s so many conflicting diagrams. Hoping someone can post a sketch of a relocation with no kill switch.

Currently I have the battery in the trunk, feed going into a 150a circuit breaker then feeding to a distribution block in the front that then goes to a 150a circuit breaker then to the fuse box and starter.

I have a second line going from the battery to a 100amp circuit breaker then running to a 100 amp inline fish and going to the alternator. There is also a dedicated 0 gauge ground going from the battery all the way to the engine block

Was hoping also to get a photo of the connections on the fuse box to ensure I have them in the correct spots. Last alternator worked a month and then wouldn’t charge, hoping to eliminate this issue, only other corner is maybe the heat from the wastegate ruined the alternator?

That sounds overly complicated. We have been putting the battery in the trunk sense early 2010's in a much more simple method and never had a single issue.
We use a distro block under the hood. This block is fed power from the alternator, it also sends power to the fuse box, starter, and the main cable threw the car to battery in the rear. We have a single 100 or 150 amp breaker/kill on the line in the car between battery and distro block. The battery is grounded in the rear of the car with a ground strap. We use either 0 or 2 gauge for main power wire size.

Do you have any photos of your setup or a write up you’ve done? Can pm you if it’s easier

I do not off hand. Essentially there is 1 cable running threw the car between battery and distro block. The battery ground happens in the trunk. Then the distro block receives power from ALT and also supplies power to starter and fuse box. Think of this distro block as what the battery used to be under the hood for power connections.

So battery box to 150 circuit breaker which then runs directly to front of the car to a distribution block. From here this runs to fuse box, alternator, starter?

Do you run a fuse on each of these lines?

 

[jed344]

When we are still using stock wiring in the engine bay we do not add any extras. Nothing changed VS the factory way other then we moved the battery farther away was all in this case. Yes to how it is routed per say.

 

[Bedicine]

So you’re sending the 2 pairs of white wires off the fuse box to the distribution block which means those fuses still get used and then the alternator and starter wires are still fed through the factory fuses. Essentially just adding a circuit breaker at the battery for protection on the long run.

 

[jed344]

Correct. Yes if you run new wires in the bay then you need to add fuses but when factory wires are still used they still have those in tact. Yes the circuit breaker is there for the main power wire run. Simple yet effective.

Are you able to help with a photo of the fuse box, in your bay to check the wire that are feeding the front and back of the alternator and starter fuses. want to ensure i have the wires on the proper sides of the terminals.

thank you

 

[Bedicine]

I was able to visit my car yesterday that’s been in storage for the winter and get some photos of how I have the wires running to the fuse box and such. Do any of these wires look like they’re connected to the wrong terminals on the fuse block?

Large 0 gauge red cable is going from the distribution block right to the starter.

The 2 pairs of white cables you can see in the photo are connected to the distribution block as well ( 2 black looms)

Two separate feeds from the trunk and a dedicated ground from the rear to the front. First post explains how I fed everything, no kill switch or intentions of adding one at this time unless it fixed my issuess

Did you paint your trunk plastic? looks great!

The 100a fuse in the fuse box labeled alternator. Is there wires hooked up to each side of that fuse? Looks like the first 60a one has ring terminals on each side of the fuse. Does your alternator fuse have wires connected to it?

Thanks. Yeah I did all of the other interior, I had a local upholster respray the dash, dye the back seats black, had him make an alcantara black headliner, redid an evo wheel, custom shift boot and armrest lid to match

I don’t have the car here but I believe the back doesn’t have anything on the 100amp because I ran an inline fuse as I pulled a seperate feed from the battery through a circuit breaker in the trunk then up to the engine bay with an inline fuse then to the alternator. I think the wire from memory going to the fuse box is because the sense wire is tied into it

Please share some pictures please

Just posted a thread on this moments ago any insight using a the enjuku wire kit.

What junction box is that for the positive?

Not a 2g like op, but I used this as my distribution block with a 2ga wire to the trunk.

I just picked up a 96 Eagle Talon Tsi AWD. i am getting ready to relocate the battery and want to mount it in the cubby hole on the passenger side. (see below circled red) This is obviously the OP picture I am using. Seeing if anyone has mounted it here and trying to get ideas. Goal is to leave the windshield fluid reservoir/pump and spare as is.

A 51R fits there nicely.
