Ford New Holland 8260 Electrical Gremlins

Hello , I bought a 8260 tractor here a few years ago and have had the same fault codes now reoccurring since I bought the tractor . I had had the dealership, two of them out to fix it an no one seems to be able to correct it. The same fault code E57, E58, E62, and last E37. I bought a manual my self and was hoping to find a whole tractor schematic in it but it only has the sectional diagrams. Is there a place that I can get a whole tractor schematic so I can troubleshoot this thing.
By the way the E37 code isn't even listed anywhere in any of the tech manuals to include the dealer version. The tech was really stumped by that one.
Tractor starts and will move unless the E37 code happens then it just stops moving. If I get any of the other codes usually I can shut it off and then restart the thing with the other codes and it start up moving again. Once in a while I have to move the dash harness around a bit but then it takes off working again. It has an analog dash in it with a high low transmission

I have no experience with this tractor, but, I have experience with bad connectors,
last one was for an electrical issue. would not charge. everything looked good.
Finally took one connector apart and found it was dirty, sprayed with electrical cleaner, and discovered in the connector block that
one of the spade terminals did not make contact with the receptacle for it. pushed terminals together and it works fine. No cost other than some time, and lots of
frustration for something I could have done a couple of years previously. I would go over each connector and check that they are good,
also follow each wire and check for a break or a bad spot in the insulation. Yeh I know, it is tedious and frustrating, but it works.
Good luck with your adventures

Sounds like a bad harness connection or a broken solder joint on the board the harness plugs into.

Before taking it apart, try to narrow down where the problem is. Move each connector individually instead of moving the whole harness. The closer you can pinpoint the problem, the less searching and guessing.

Once you find it, try cleaning and reseating the connector first. If they corrects it, great!

If not, take the dash out and carefully inspect the solder connections around that plug. a jewelers loop works well, look for a crack in the solder around the pin.

That type failure is usually stress related, as in the harness weight hanging on it. Try to secure the harness so it is not hanging by the connector.
