So I guess in 1st it is not going into low range so it is in 3rd[/QUOTE]
Correct.
If you pull that relay and the right prong doesn’t light up in 1rst, then I’m guessing you have a bad contact in the selector handle on the steering column.
Maybe try jiggling it back and forth between 1rst and 2nd a bunch of times to see if it frees up. That handle will be expensive through JCB.
Again, on my machine, the Layshaft/Mainshift relay is second from the right. Not third from the right like the book says. I’m guessing the machine you’re working on is the same, and the mistake is in the book.
