88-98 Service Manuals

[GoToGuy]

A two fold reason. One more and more electrical control, activation, feedback and monitoring. Therefore a more thorough and logic layout for diagnostic and repair.

You are awesome for doing this for us. Also, Tom Baker is the truth!

Glad to hear that the '99 FSM is matching up with your '00! And thanks for coming back and
sharing this so other 2000 C/K truck owners out there now know that these .pdf files can be used as
a reference to help fix their rides.

NOTE: @hatzie shared so many manuals in the first reply, but the '99 FSM .pdf files that I wanted
(to supplant my paper manuals) were missing, and it took me awhile to find the links that @PM18S4
shared in reply #77. So again I'm happy to hear that this is working out for you.

****

For what it's worth, by the time the '99 C/K manuals were printed, the GM technical writers
had changed the way they documented the wiring harness for the better. One thing I like is
the way that every page is organized with the power source for the circuit is at the top, and
the grounding for the same circuit is at the bottom.

They also improved the way they documented the physical location of splices, connectors, and
grounds. If you end up having to work through some electrical issues on your '00, you might
find the following discussion of how the electrical section is laid out to be helpful:
(Quick tour of the General's new wiring diagram layout)

Best of luck with your 1 ton --

Similar to Volkswagen in the 1970's. Power at the top, ground at the bottom.
My 1977 VW A1 & B1 chassis shop manual wiring diagrams are organized that way.

Over the years I have collected a bunch of GM service literature.
Links to PDF Scans of service and STG manuals and a links to the Parts manuals. You'll need the FREE Adobe Acrobat reader to open these files. Get it directly from Adobe here {http://get.adobe.com/reader/}
If you're not interested in Adobe products there are several lightweight alternatives. wikipedia.org List_of_PDF_software
TechRepublic Review of five-lightweight-and-free-pdf-viewers/ an important fact they left out is... Foxit is Ad supported so factor that in.

Please Save these files on your local machine. Do not open in your web browser. The Mediafire PDF reader is not compatible with the Searchable PDF document type. The OCR text is visible along with the page image in the same space.

If you're good at loosing files Google "Void Tools Everything" and download direct from the developer. I've used this file search tool for years. It will find any misplaced file...

It looks like Mediafire has begun compressing PDF files as .gz GZIP archives. You can un-compress it with a universal file archive tool.
I use 7-ZIP because it opens darn near all archive formats, it's lightweight & fast, it's free, and so far it comes with no spyware or adware. http://www.7-zip.org.

These scans make a nice electronically searchable reference. But. I highly recommend buying used or even new paper copies. There's nothing like holding the book in your hands...

Useful Docs and Spreadsheets
What follows is an Excel 97 spreadsheet I put together several years ago to calculate the Speedo gears and engine RPM at various highway speeds. I was doing a "What-If" on transmissions, tires, and axle gear-sets and wanted to get transmission/transfer-case speedo gears as close to correct as possible. My 76 reads 1-2mph higher than actual speed. If my speedo reads 35 the local police dept's "Your speed is this" sign will read 33 or 34.

For the RPM tables you'll need to edit the transmission and Transfer case gear ratios as well. There are tables of ratios found in common trannys and transfer cases in the RH pane.

• RPM_Gear_Axle_Transmission_TransferCase.zip archive with Excel 97 XLS format and Libre Office / Open Office ODS format.

The Free Apache Open Office Suite https://www.openoffice.org/ and Free Libre Office Suite http://www.libreoffice.org/ "Calc" Spreadsheet applet in 4.x and newer versions. Libre Office and Open Office 4.x & 5.x will open and edit spreadsheets in Excel 97(XLS) & 2007 and newer (XLSX) formats but the formatting is better in their native ODS version. I lean toward Libre Office because the dev cycle for bugfixes and new features is shorter. Google Docs should open either the ods or xls file on the web as well.
.XLS files sometimes have visual formatting issues in Libre Office and .ODS files have formatting issues in some versions of Excel. They will both open in either office package but I included both for more appealing visual layout in the office package of your chioce.

There are no Macros or VB Scripts. It's just a spreadsheet with some fairly complex formulas and color formatting.
MAC OSX and Windows Operating Systems since Windows XP have been able to open ZIP files without extra software if the functionality is not disabled by system policies.

If you don't like using 7-Zip from the command line in Linux there's a GUI called PeaZip

Thank you so much for all the work you put into this

 

[BeautyandtheBeast]

Thank you for the link! The infor there is actually very helpful for me. I have an electrical disaster I’m trying to work out and it’s such a nightmare I’m not even sure how to write it all down to post as question on here yet. I’m hoping I’ll be able to at least narrow it down far enough to a few possibilities so I don’t have to post a 10 page manuscript looking for guidance. I’ll be sure to report anything I find along the way tho so others can use the info.
