IH manual for 364 question (manual #GSS1442)

My manual GSS1442 reads 354/364/2300A Tractor Chassis on a stick-on label on the upper right front cover. It says CHASSIS 354, 364, 2300A Tractors on the first page of the book. This page is some kind of revisions page and perhaps it was a revision which added the 364 model as being covered by this manual. The next page says 354 and 2300A Tractors. From here on and throughout the book there is nothing specifically written mentioning 2300A or 364. Engines mentioned are BD144 (Diesel), BC144 (gas).
This is not the only manual for the 354 tractor and there may be others specific to 364. I also have an IH Operators Manual for 354, (the number is missing), an engine overhaul specs manual covering BD144, BC144, BD154. The number is GSS1358. I also have a parts manual BT19 for 354 and 2300 Tractors. Have you contacted Case IH dealer or Case IH directly for a list of publications available for your particular tractor Chassis serial and engine #. I would suggest you do this and have them tell you what manuals apply and how to get them. Small problem, you can spend a small fortune on manuals. In my case, with this tractor in a million pieces, I need all of them and maybe more.

ITIH 201 IT Shop manual

Hech Lee, the way I see it from the list above, if the GSS1442 doesn't have electrical schematics then surely none of the others do. I guess IH never put them in a manual? Maybe the ITIH201 manual has them? Have you ever seen the IT manual on this tractor to know for sure? The tractor I'm buying has been rewired by my friend that currently owns it but the charging system isn't working and the glow plugs are there but not working. He had problems keeping the glow plugs working even before the rewire so he simply didn't wire them back up. I used to run this tractor for him cutting hay several years ago. We could use sandpaper to clean the wires between each glow plug ever so often and they would work great for a month or so. They never appeared to need cleaning but this seemed to work. Someone on this forum (was it you?) said they had the same problem with there 364 and they said it was a fault of the glow plug switch. He said he replaced the switch with an old floor mounted car starter switch and his have worked fine ever since. Have you ever heard of this glow plug problem on the 364 and 354's? Also, I am interested in your comment about me working on the 364 myself because it's unlikely I'll find a dealer that will know anything about them. First let me say, I will do everything to the 364 myself. I love working on my own equipment - it's part of the joy of owning it to me. But still, that being said, are these tractors that rare and obsolete that dealers don't know much about them? Heck, it makes me wonder if I should go ahead and buy the thing if they are so rare? I surely don't want to own something that I can't get parts for and information about (like the electrical schematics). That statement kind of scares me about my 364 purchase???
