I need to replace all the cables from my batteries. Anybody know what size diameter and/or length they are.

Secondary Battery:
Positive
Negative

Primary Battery:
Positive
Negative
Alternator lead

Seems like there is another small wire in there someplace but I'm drawin a blank on what it is right and to cold and late at night to go check at the moment.

Thanks

 

from the top of my head is seems like a 4 guage wire

 

Check this out, I took the info from this website and was able to make my own. Worked really well

http://www.custombatterycables.com/ click on the Dodge ram listed in the left column and it has all the information you need, including length.

Great site listing Gary, Thanks.

Now can anybody tell me where all the smaller cables lead to off of the batteries. I'm in the process of movin my batteries to an in bed tool box and have to figure out where all these leads go so I can figure cable lengths.

 

Excellent site ....

 

He talking about a Cummins - a whole different animal.

 

Negatives go to grounds on the frame etc. On the drivers side positive - one lead goes to the passenger side battery, one to the starter and one to the PDC. I used 2/0 welding cable for mine and used awg #4 for the PCD and grounds.

If you are putting batteries in your toolbox I would say you should definitely use 2/0 to keep voltage loss to a minimum.

 

I am using 3/0 from tool box to where driver side battery is ( was ) using 3/0 male/female conectors for quick disconect. Bought a 25' roll of it.
