LS 3037h maybe others. Quick check

[trukker]

Hey,
Hope someone can look at their LS 3037 ish tractor. I have been having an frequent issue with limp mode. Took tractor to dealer to check codes. Tractor would not go into limp mode until diagnostic computer was unhooked from tractor. Finally figured out we had to start tractor get limp mode and read codes got a 723-4. Replaced #2 speed sensor worked great for 2 hours. Yeah all fixed, NOT! Started doing the same thing going into limp mode. Checked continuity, sensors and all looks good? Starting to get frustrated. This is the short version!
Can anyone look at the battery and take a picture. Looks like mine is missing a Fuse that should be on the + battery terminal. Just want to confirm that it is missing.
If this does fix the issue I will share the full story and hope for some help.
Thanks

The blue part is the fuse. However, you're missing the clear cover for it. Looks like the connections could also use a clean up to make sure everything is making good contact.

It should look like this:

Thanks, mine does not have fuse in it. Looks like it should be a 100 amp fuse according to ls parts diagram. If that is what is missing kind of crazy it is still running.

I believe Ptsg is correct. The copper piece in there is the fuse, see where it gets narrow, that is the weakest part, the 100 amp limiter. Once the draw exceeds 100amp, that thin part will melt and open up.
It's actually a fuseable link.
