Replacing battery cables, question regarding positive terminal
 
Still working on my 'resto-mod' project. I plan on 'rebuilding' the battery cables with new terminals, lugs, and quality welding cable.

I want to replicate the stock layout, but I don't know what to do with the positive battery terminal. In stock form, there are two cables that come out of the positive terminal, one to the starter and the other to the fusebox.

Looking at replacement battery terminals, I can't seem to find one that will accommodate two cables. I'd like to avoid just jamming two cables into one of those ones that uses the bolt-down clamp. Any products available that I'm missing, or should I slightly modify the stock setup? I suppose I could run one thick positive cable to a junction near the battery then run the two cables from there.

You can either terminate with a crimp ring terminal and then find a battery terminal that can accommodate those ring terminals or find a battery terminal that can accommodate the two bare wire ends.

If going with #1, you can just stack the ring terminals.
There are lots of options for battery terminals that you should be able to find locally.
Most common are the ones with wing nuts on the top.

For #2, check out "car audio" type battery terminals that allow you to shove bare end stripped wire.
Most can accommodate up to 4AWG easily.
Some have multiple holes to accommodate what you're trying to do.

Ted is right.

Stinger makes a bunch.

Here is a place to start from. Get some ideas and see what's out there.

Or this type, if you're trying to save money...

You'll still need crimp rings to your existing wires to connect then under the wingnut.

I use welding cable as well and I have two cables from both battery post using stinger clamps .

Crimp the starter wire in that and crimp and eyelet to the other cable and bolt it on.

Or, what I would do personally is get a powerpost and run one cable to the powerpost and then split from there. One of my biggest peeves and rules about rewiring is - 1 wire per battery terminal. I counted... and I shit you not 17 different wires on 1 battery terminal once. Guy wanted me to install a bilge pump.... I billed him $2800 because I wasn't going to touch that shit, I rewired the entire boat... little 18' whaler

Thanks for the advice, fellas. I hadn't seen those car audio type terminals before, they look like they'd be a good option. The wingnut type would definitely work as well.

I'm leaning toward TTT's solution, though. Mainly because I'd really like to use a terminal that I could solder and heat shrink (like this). And the 'one wire per terminal' thing seems like a good rule.

Crimp! don't solder! :)

I do generally prefer crimping, but I've never seen a battery terminal crimped before. What tool do you use? The one I saw on a quick search has a pretty scary price tag :07:

EDIT: The ones I was looking at were the bolt cutter looking kind which run $2-300. Would a hammer type be appropriate for a battery terminal? I plan on buying one of those anyway for the rest of the cable lugs.

Here's what I use.... not a scary price tag and will do 8ga to 4/0

I would much prefer using that.

I was given a Anvil style crimper a while ago so I just use that. Its a little awkward but makes solid crimp, though not the cleanest.

^similar to this.

^mine looks just like this

TitaniumTT 03-20-2014 10:34 AM

Yeah.... they work, but they're kind of violent... and you never know if you're getting a proper crimp or not.... with the crimper, if the handle closes, you know you're done...

$70 is still a little hefty (I'm an FC owner, remember :p). However, it's probably worth it for a job well done. I'll probably end up buying that one eventually. It's not like I'll need to build the battery cables anytime soon, anyway.
