Let me get this straight?
Are you telling me on my 96 F150s 4.9 that I am powering my starter with a measly 8ga wire?
I run that as a alternator lead on GM 1 wires!
My starter only draws a maximum of 70 amps!
My old truck I had 0/2 gauge welding cable for starter and battery cables. This is insane. I could see 4 ga or mayby even 6 ga but 8?
I think it is time for me to make me a set of custom cables with some 2Ga leads and a 4ga runner. Also, How did ford expect the chassis ground last being exposed as it is?
Someone please tell me I am wrong here. This is slightly disapointing. You are loosing nearly a volt to heat loss. Starters draw well over 100 amps. Is this why my 1964 has the original starter? That 4 ga wiring simply gave it the dang juice it needed.
Wow, I am confused.

Ive never heard of anyone having problems with stock starter wire.
But I run 1/0 for my alternator so I guess im a little different than you.

8 gauge overkill??? heck i barely trust a 8 gauge to power my little 300 watt amp in my ranger lol, i dont see any damages happening going too big, but if you undersize then things start smoking and what heaapens afterwards is never a good thing lol

The wire from the starter relay on the fender only powers the starter solenoid the is mounted on top of the starter. The starter is now a gear reduction starter so it uses less current to operate.
Also, How did ford expect the chassis ground last being exposed as it is?[/quote]Here is the chassis (body) ground in the image below, what is wrong with it?
The engine is also bolted to the NEG cable and that is the one the starter current goes through.

That ground you are showing me is for the headlights.
The chassis ground is down on the framerail below the smog pump. It consists of the wire being stripped back for an inch or so and a crimp on lug being added. Then the wire continues back to ground off my engine near the starter.
The diagram helps with the positive side. Now I understand the 8ga purpose. Than can probobly remain 8 ga.

As I said above the lug on the frame is not used by the truck. It is only used if you are pulling a trailer.
The ground in the photo is used for everything that is not engine mounted on the truck and not just the headlights.
