Thanks for your post it saved me this week. My trans would not lock up because a vac switch failed and i probably wouldnt have figured it out as quickly as I did without the wiring diagrams you posted.
Thanks again,
Dan

Re: PDF of Square Schematics & GM Training Manuals
 

I'll be scanning and posting some more 77-91 service manuals over my Christmas '12 vacation.

I've found some specialized unit repair booklets, tech training booklets, and 67-71 10-60 series service and overhaul manuals to scan as well. The 67-72 manuals will prolly wait till the square stuff is scanned. ;)

If anyone has the foldout ST352-81, ST352-82, or ST-352-84 wiring manuals and would be willing to let me scan them PM me. If you're in NH, RI, or Eastern MA I can meet you. I will have to CAREFULLY remove all three binding staples to run the pages through the scanner. My manuals are as original now with the exception of some brandy new staples.

I guillotine the binding glue off the service and unit manuals. So I'm only scanning manuals that are in kinda tough shape to start with. They are complete but the covers and first few pages are generally loose or barely hanging on and some have some truly impressive dog ears to fold out and press/iron flat enough to carefully feed through the scanner.

For anyone who cares about this kinda stuff...
I'm scanning these as text-under-image searchable PDF files. What you see is the original image complete with tables and proper formatting. This method uses OCR text for text searches and cut-n-paste operations. Otherwise it's hidden... as are any errors in the transcription.

I use a Fujitsu FI5530C2 sheet-feed scanner using 400x400 dpi greyscale with modified brightness and contrast settings.
Software is GIMP for long sheet wiring diagram bitmap image splicing, ABYY Finereader 11pro for OCR, and Acrobat 9 for final PDF optimization.

Re: PDF of Square Schematics & GM Training Manuals
 

so cool! looking forward to your PDF's...

Re: PDF of Square Schematics & GM Training Manuals
 

hi is this worth picking up for the Jimmys

Re: PDF of Square Schematics & GM Training Manuals
 

The paper manuals are definitely worth getting. You can usually pick them up fairly cheap for the exact year if you're patient and aren't too picky about covers and greasy fingerprints.
PDF files are not as garage friendly if you don't have a hardened PC.

I have the ST330-79 & ST330-81 service manuals in the queue. They had no covers but only cost $4...

Re: PDF of Square Schematics & GM Training Manuals
 

Uploaded several 76-91 service, emissions, and unit manuals.

92-98 Auto and Manual Transmissions and Transfer Case Overhaul manuals. There will be no more 92+ manuals posted.

Uploaded new training manuals. T400 Electro Motor Cruise Control, GM Diesel Fuel Systems, Power Steering...

Re: PDF of Square Schematics & GM Training Manuals
 

Added Diesel Training manuals for 6.x engines. I'll add the 5.7 manual if I can find it.

Re: PDF of Square Schematics & GM Training Manuals

Re: PDF of Square Schematics & GM Training Manuals
 

Nice work !!!! got me subscribed!! you going to do earley years???:chevy:

Re: PDF of Square Schematics & GM Training Manuals
 

67-72 are mostly done see my sig.

TOCMP.COM and the Stovebolt guys have the 20's, 30's, 40's, and 50's covered fairly well.

I don't own any of the 1960-66 manuals.
Wiring manuals are scarce as you go further back in time they get harder and harder to find.
It would be a fair amount of time and effort to find, acquire, trim, scan, process, upload, and catalog them.

I would be looking for shop-grade "ABE books poor grade" rough condition books (all the pages are there but... missing/torn covers, dog-ears, greasy fingerprints, etc). I used this grade of book for the 67-84 scans. The older manuals are collectible books and cost accordingly. The spine trimming process destroys the collectible value even if the pages are re-bound.

If I can find a source of the type of books I'd need for an inexpensive price... or... If anyone would be willing to sacrifice their rough shop-grade books I'd give it a shot. I'm not expecting a large number of folks who would be willing to do that.

Added Gen I Olds 350N Diesel STG Training Manual

Re: PDF of Square Schematics & GM Training Manuals
 

I got that 81 book yesterday,
I've never had one before but even just the 5 min of flipping threw it it's worth the $20
said he lived quite a ways north of me,went to a few family members,to a cousin, i met him here in town
it has a chunk of photo copies for the TH 350 stuck in it
very little ,marks or "useage"
i'd given up on it

Re: PDF of Square Schematics & GM Training Manuals
 

Thanks for this.
Much appreciated.

Re: PDF of Square Schematics & GM Training Manuals
 

This is a wealth of info. Thank you!

Re: PDF of Square Schematics & GM Training Manuals
 

thank you so much for making these available, I have a parts book for the 86 Astro vans and I am thinking of scanning it in for others if there is an interest.

any one know if someone has done something like this for the Dealer data books? I want to find one for an 85 GMC. I have a preliminary one but it has no prices.

Re: PDF of Square Schematics & GM Training Manuals
 

Wanted to thank you for this as well. It is really helpful! I looked online a long time looking for these and only found those places trying to sell you a copy of the PDF of the manuals for $20 a piece.

BTW, I have a server I can put these on to serve as another mirror for you if you want. I have unlimited storage and download limits. So a couple of GB's is nothing.

Let me know and I will put them up ;)

Re: PDF of Square Schematics & GM Training Manuals
 

Why is this not a sticky?!

Thanks very much for the information. The driveability manuals are chock full of diagnostic procedures and information that is INVALUABLE to those tracking down problems.

Any chance of a 1995 service manual?

Re: PDF of Square Schematics & GM Training Manuals
 

If you own one you'd be willing to have trimmed and punched. What you'd have then is loose-leaf hard-copy and searchable PDF. :lol: :D

Re: PDF of Square Schematics & GM Training Manuals
 

why dont the links open?

Re: PDF of Square Schematics & GM Training Manuals
 

The server is purposely up and down at random times. Right click and save as. Don't Open in your web browser.

Re: PDF of Square Schematics & GM Training Manuals
 

Hatzie, I have a 1980 Truck wiring diagram that is different than the one that you have scanned in. I really appreciate your work on all this valuable information, just want to help and contribute anything I can. Send me a PM with the address and I'll send it to you to scan in if you wish.

Thank you for this! A Google search brought me here. I just purchased a '73 Sierra Classic 15 (454 auto.) and this will make it so much easier to work on my pickup.
