Those two black wires from the terminal bolt are grid heater feed wires.

The large black cable out of the terminal itself is Alt feed like you think it is.

The red wire coming off the battery is a power feed. I'll look in the manual to see where it goes.

The brown wire coming out of the weather pack connector is starter.

Thanks Philip...
I thought the black wires were for the grid...Since I'm using them as taps for my headlight relays I'll prob swap them also.

OOPS !!
I don't have a brown wire...Could that be black ? Like the one in the center right side of the pic? If so, I suspected that was the starter relay but wasn't sure...That one goes also.

What about the red and black pair? Any ideas?

:CRY::CRY:
Don't know how I got the message duplicated!!

Anyway - :butt: That's where my head should be...
The pair of wires is actually red and BROWN :butt:

So - that takes care of that. I followed the wires for a short ways and will not move those wires.

That one we called red is pink on the wiring diagrams. It is a direct feed to the 4 way flashers. The brown wire in the same plug is starter.

Bad news...
First I've been tightening and loosening the terminal so much removing wires and replacing wires that the positive battery terminal cracked ! Where the bolt goes through the holes..
Oh well, the terminals, wires, and connections look like they're original...13 yrs old, it's about time they broke.
Second - darn meter needs the shunt mounted in the negative terminal !
All that work and it was on the wrong terminal - and the wrong size...I can see me starting the truck with a 200A shunt in the circuit --- poof!
So all is on hold until tomorrow when I can get a new batt terminal.

And - does anyone know what the current draw is on our starter ? Assuming it doesn't stall . Shouldn't be much more than 600 or 700A...Or I am too high ?

 

[Philip]

Your high on that guess. I did a current draw test on my starter years ago. With the fuel solenoid unhooked it pulled 375 amps full load spinning the engine.

If I remember right the grid heaters pull around 50 amps.

Larry I was just digging around in the FSM and happened to run across the rated starter AMPs. It says 450-550 AMPs.
