Theta's posts were great in 2014 taken from the Service Manual he had electronically as I recall, certainly well before the printed copy as I got one of the first.
However when changing batteries some of those Service Manual instructions are useless! For example, to remove the power block, per the Service Manual, it just says, “ Release the tabs on the fuse block." Love folks who write manuals, you wonder if they ever worked on a car!
I made a PDF that shows how to do that, it's NOT obvious as there are some other tricks:

For that one item below is one of the 22 pics with text from the PDF. It starts with something NOT in the Owner's or Service Manual, "How to get access to the battery without ripping the carpet!" A poster mentioned the Chevy dealer tech ripped his carpet. Call AAA to jump start and that person will no doubt rip it!
To release the tabs you first have to know where they are and how! No info in the Service Manual! It is not so obvious!

FWIW, see post #12. The 4 volume Service Manual is of no help! Typical, it says things like "Remove Power Board" (which is on the positive terminal and held by clips to the battery case) but gives no idea as to how! My picture PDF's shows what I found that took a bt of trial and error.
Also no where, Owner's or 4 Volume Service Manual show a simple way to avoid cracking/ripping the cheap carpet which is not bound under the right side plastic wheel well cover. It's simple, just disconnect the clip on the bottom rear side before pulling out carefully!
SIDEBAR:
WHY I MAKE THESE PICTURE PDF'S
Throughout my working carrier spent a lot of time with our sales engineering and regional engineering managers in 7 regions. My area of expertise was welding process and welding filler metals and shielding gases. I continually heard how bad our welding equipment instruction literature was, often wrong and confusing. I managed the welding processes and filler materials Lab but had little to do with the equipment engineering or manufacturing effort that was in a plant 1000 miles away from our facility.
After forming a leveraged buyout of the welding business from the very profitable industrial gas business of a multinational corporation I worked for the CEO managing all customer interface functions including business managers, customer service, training and marketing communications. My chance to fix the instruction literature! The manager of the department was a great fellow and had two writers preparing instruction literature. Found they did a 1st article assembly and installation of a new product. The writer would work with the engineer who designed the product. In fact he had been communicating with the head engineers since the development started.
As expected, the writers said the engineers did not like to take time from their development efforts in helping with the instructions and would not read the final drafts carefully. Sure just like I read what I think should be there, I'm sure they did the same. Having managed engineers in my process and materials area, understood they wanted to work on new products and writing was often not their skill.
Simple solution:
That first article assembly would be conducted the other writer who did not prepare the document! Met with the VP Engineering and got him to agree to have an engineer who did not mind detail work, and was not involved with that product development assigned to work with the writer!
It was not surprising, that there was instant recognition of the small issues that were creating most of the past problems! Things like "Remove Power Board on the C7 Battery" would be accompanied with a sketch of where the clips were located and where to put the screw driver! There are many areas in the 4 C7 Volume Service Manual where it was obvious the person writing had never had to perform the function being discussed! Been retired (we'll semi) 20 years and have the time and have fun making the "How To" PDF's with were I ran into issues and simple tricks. Recall posts where a dealer Chevy Tech ripped the carpet when gaining access to the rear area! Probably did better on the next car!
About 2 years later recall, asking our regional engineering folks about the Institution Literature. All said it was "great" and loved the sketches and pictures included!

Thanks Joe. Always chuckle at instruction literature written by folks who never actually did what the write about! Love the "remove power board" statement with no idea as to how!
Be careful when working with batteries. This was in my Case tractor. I had an automatic charger on it. I removed the charger and reached around to turn the key switch on to see the fuel level. I turned the key to acc. and pow, the battery exploded. This thing sounded like a rifle shot. Brother heard it in his house 1/4 mile away. I've had bulldozer batteries pop on me but nothing like this one. My ears were still ringing hours later. Nothing wrong with tractor wiring either. Put in another battery and away we go.
