I'm getting a new positive battery cable made, but I wanted to make sure I knew what I asking for.
The cable that goes to the solinoid is split in two, correct? Or is it just made to look like it is, maybe to secure it better?
If it is split in two, how does that work, why does it not keep powering the starter like jumping the two posts with a screw driver?
Thanks in advance.

 

Apparently you're talking about the '92 or '93 in your signature. The starting system on the '92 and newer Fords is set up different from the '91 and older Fords.

The positive battery cable runs direct to the starter(as well as the fender mounted solenoid) thus the split in the cable. On the '92 and newer Fords there is also a solenoid on top of the starter to activate the starter when it gets the signal through the fender mounted solenoid(also referred tom as a relay).

The '92 and newer design has the advantage that the full power to operate the starter doesn't have to go through the fender mounted solenoid(relay).

 

The rubber thing on the end of the cable at the relay (it's a relay, not a solenoid) has two separate wires in it that are not connected to each other. One is the thicker wire that goes to the battery. The other is thinner wire that goes down to the starter solenoid. You don't need that big rubber thing on the end. Cut the smaller wire from the rubber thing and crimp or solder a ring terminal on the end of it, and reattach it to the relay. Then you can use another regular ring terminal on the bigger cable to the battery.

 

Thanks guys that helps a bunch. Now I can go get my new cable made.
Yes I know now I can just get store bought cables, but I'm getting better quality cables and they will be thicker. I believe they will be 2/0.
I'm also finally doing the 3g swap. I went and got the altinator from Pick and Pull for 17.00 out of an 2000ish Ranger. I actually don't know what year it was. It wasn't on the 3' list they gave me.
Anyways I'm also having a new charge wire made with a big fat fuse holder. I believe he said it will be a 150 amp fuse.
I have to read up in the sticky to find out which gauge that wire has to be.

 

The Bronco site says the charge cable is 2/0. The same as my new battery cables will be.
