Electrical Diagrams for 3910

[BBlocker]

While I was investigating a power steering leak, I thought I'd check everything else out while I have the covers off the tractor. Looking at the wiring, I noticed that there were a bunch of loose wires that weren't connected to anything. Tracing them all back, they all go to the fuse box. It looks like the previous owner cut all the wires to the fuse box and hardwired everything. I guess that's why the fuel gauge doesn't work. :confused2:

Do the ~$30 service manuals (I think it's the FO-43 for the 3910) have the electrical diagrams in them, or would I need to buy the more expensive shop manual?

Also, does anyone have experience with the tradebit.com website? I found a e-book (PDF) shop manual (2542 pages) for $60 on their site here: Ford New Holland 3910 Tractor Repair Service Work Shop Manual - Download Documents / eBooks. It's tempting, but I thought I'd reach out first to see if anyone else has had experience with them.

I have a FO-31 I&T Shop Service -Ford Shop Manual. And it has (2) wiring diagrams. The little books are pretty condesnsed. I have never seen the big books to compare. I suspect the little books don't give the details of all options and models. But if you have the basic or most common style of the model it should be worth the $30.

I have a subscription to alldatadiy dot com (for my truck) and its pretty equivalent to my official Helm GM manual. Even with the big manuals sometimes the description and instructions for repair are very basic with few hints to make the job easier for a shade tree guy like me. And keep in mind you might get frustrating looking for info in the big books. I dislike my helm manual's organization.
