What size of battery cables

[Slydinclyde2]

What size cable do you guys run from battery to battery and to the starter? Got the truck home today and the battery's were flat dead may have a drain on them somewhere. GP controller maybe. The cable look like hell. Any battery preference brand and size? I know only like 3 company's make batteries with different quality control for the higher end batteries.

I have double 0 gauge wire in my truck.
im also running some group 31's
she never has an issue turning over!

 

[Slydinclyde2]

That's along the lines I was thinking. You run your grounds to the starter?

 

[Slydinclyde2]

Did you have any fitmet issues with the 31 series? Found some at a tractor supply store for $100 a piece 970 cca

The grounds run to the bottom of the front part of the engine block right above the oil pan.

I saw that's were they are currently just figured cut down on som resistance by mounting one to one of the starter mounting bolts.

One on each side of the engine correct?

 

[funnyman06]

Yup, one on each side.

If I remember right stock grounds are 1/0, batt to starter is 3/0 and batt to batt is 1/0 I believe, I'm going 4/0 for everything.

Group 31's fit fine in a bricknose, but not in an OBS. If you fill out your signature and tell us what truck you have it will make it easier for folks to answer some of your questions.

Thought I did my sig but guess I got sidetracked. Fixed now.

When mine had issues I replaced the hack job made wiring on mine with a new "one piece" from NAPA. I could have gone to the local battery shop and had them make one as good or better cheaper, but it would have taken a little time I didn't have.

I have custom batt mounts, #1 under the hood, #2 on the frame under the pass front seat.

I have lots of grounds. lol

2 main grounds from battery to the engine.
#1 bat also ground to the core support.

My truck has a factory 4/0 cable between positives and to the starter, needs replaced one of these days, but I'll keep it at least that large.
