6" lift. 3/4 ton axles.
I actually am enjoying it so far.
Just time consuming.

The biggest thing is I wish I had the engine out and could roll the truck out to wash it and clean it up underhood first.
 
Question on charging / starting circuit

Alternator goes to the big post on starter and the junction block.
Starter goes to junction block also.

Can I not skip one of those wires? Can’t I just run both the starter post and the alternator to the junction block and have them link up there?

Same with the fuse block. It has a wire to the junction block and one to the starter big post. But the starter also goes direct to junction block. Can’t those two just T together at the junction block?
 
It sounds like you have some redundant wires. So I would try to simplify things. I personally don't run any more wires or cables to the starter than necessary so that there is less to protect from getting cooked by the exhaust heat.

But try to plan out routing some before you start cutting cables. Maybe use some rope or hose to lay things out, use some painter's tape to hold stuff in place and see how the cables lay into the engine bay.

My '90 Jimmy has the alternator charge wire going directly to the battery post, and 2nd wire to the junction block, and then I believe that it has a wire from the junction block to the starter. Of course then battery cable to starter.

I believe that is what I remember..
 
Edit:

/\ what he said

Should be fine your way.

FWIW, alternator should probably go straight to the battery

Actually used bailing twine. I keep a box that I got from tractor supply like 10 years ago. Works great for that type of stuff.
 
I have a question about fusible links.

By remaking all of those power cables from alternator/starter/junction post out of larger cable, I’ve effectively deleted the fusible links.


Do I need to be concerned about that? Should I add some fuses/circuit breakers back in line?

I will have a circuit breaker isolating the batteries from the truck, but I guess there is nothing from preventing an issue between the starter and fuse block or the alternator to fuse block.


Thoughts?

I always kinda wondered this myself. I always pulled the fusible links out of my demo Derby cars and never had a problem but I don't think that should be a Golden standard by any means.
I think as along as you have a breaker/fuse/controlled point of failure to prevent the whole truck going up like a 2 month old Christmas tree, your fine.

That’s kinda my thought. Everybody goes and upgrades / upsized the battery cables to the welding stuff so it must not be a huge deal
 
I put some heavy duty fuses in Big Ugly when I accidentally arced the battery and melted a terminal and fusible link. Got them at Home Depot.
 
I’m not worried about the battery side as that will be controlled by the circuit breaker. The only place a problem could get me is if it starts in the alternator/starter and travels towards the fuse block.
 
Still chipping away. Took tomorrow off so I’ll do some more work this weekend til I run out of parts. I’ve got everything off the fuse block finished up. May wash it and put it back in.

Also got my weatherpack tool so I can finally start wiring the electric fans that started this whole damn fiasco.

Looks like he forgot paint for the battery bracket.
He sure didn’t. It’s coming out to get sand blasted and painted when I spray bomb the engine bay. I’m pretty confident I’m gonna get everything figured out then pull it for paint and cleanup.
