So where do I start now?

Due to thieves stealing the batteries off my most useful tractor, I've been taking the bats off each evening and carrying them to my one lockable shop garage . Next morning carry bats to tractor and re-install. Tractor too big for the garage. One terminal is quite close to the fuel tank and I always wedge a piece of hard wood between the terminal and the tank. Well today while running the discbine I smelled smoke and looked down to see major flames. Shut down, flames spread fast all over the 48 years of dirt and grease. I finally smothered the fire with many handful of green hay, I mean many balls of green hay. One battery burnt bad, many wires charred, hands took a beating. 1970 Int 826 and by far the best of my 14 tractors and it has never started and ran as good as lately. Where do I start? All new wiring harness? Who sells such?
 
Is the wiring so far gone you can't start replacing one wire at a time? Just thinking that may be the fastest to get you tractor up and running again. Of course if you don't have two good ends to splice to, sorting it all out is gonna be tough. Sorry to hear of the thievery in your area, and the lengths you must go to to stay operational. Hope someone can be helpful. gobble
 
Without seeing it, hard to say...

Generally a wiring harness can be saved from an external fire.

Just start carefully sorting it out, pulling and separating each damaged wire, splicing in new wire where the damage stops.

Take it one wire at a time, don't let it scare you. Tractor wiring is basic and straightforward. Try to match the colors, you'll be glad next time you have to trace something down.

If it burned internally, as in shorted and burned the entire length, it can still be cut open, and the damage repaired, just more work.

You can buy split black plastic wire harness cover in various sizes at the auto supply. Neater and easier than taping.
 
Only place I can find the wiring harness is from CaseIH at 191 and change.

I'd see if someone had a wiring diagram and just rewire it myself.

Had an old pickup that the wiring harness caught fire it took several long long days of separating the melted wires and splicing in new sections . I know Steiner tractor parts sells wiring harnesses for some tractors they might have one and then you?d be set up .

An 826 is similar to an 856 or 806 for wiring except for the glow plugs if it is a diesel. They are a very basic harness You coule even just wire it to charge and run then finish the rest next winter or during an off season.
After 40-50 years of deterioration most of those old wiring harnesses are about shot on those IH tractors anyway. IH used some really poor grade material in their insulation. We have enough models and ages to prove it too.
 
Try Porch Electric in Illinois, when I dealt with them years ago they made their harness' from original IH blueprints.
 
Last summer I was given a IH584 because it had burned due to a lightning hit. I had worked on it in the past so the guy figured if any one could do something with it I could. hauled it home and drove it off the trailer under it own power. All the wires where gone battery burn past being a core. Radiator was melted badly and had to be replaced. Hoses burned off etc. To this day it ha only enough wires to make it run. A simple wire to start it and a new alternator wired in such a way you have to touch the excite wire to the charge stud to excite it. It also has no dash due to it being burned off and the seat on it now came off a riding lawn mower but it does the job as is
 
These guys have wiring harness for just about all farming stuff. Page 29 in there catalogue has the harness for your tractor...

I just bought and installed a new wiring harness from agri services for my Case 830. happy as a pig in punch everything fit perfect even up graded the alt wire very good quality. Just took a coupla weeks for them to make it.
 

When working with old wires I use my pocket knife to scrape the dirt/film/soot off enough to be able to ID the color.
 
Thanks, everyone, for the ideas and shared knowledge. We finally got a few hay days and I had so much hay down that I barely looked at the tractor since the fire. Looks like four more days of rain starting Tue so I'll tie into the mess.
