I have an L2350 Kubota tractor that I've owned for about 7 years.

A bit of important back-story:
Recently I replaced the battery. The new battery was the proper number of Amp-hours (actually more than the battery it replaced). I also made sure to get one that hadn't been sitting on the shelf too long. I managed to remove the old battery, slip in the new one, and hook it all up. But the way I hooked it up was a bit unprofessional, due to the fact that I didn't want to take apart the whole front-end of the tractor. The new battery has posts on the front, not the top, and I secured brand-new battery cables to those posts (terminating in a standard metal loop).

I put these metal loops inside the old "battery clamps" which used to go directly on the battery. I bought new bolts/nuts and made the connections good and secure.

The tractor started fine, and I drove it a couple of times.

But recently, as I was driving it, I heard a small "pop" and the whole thing just died. Basically the tractor acts as if it doesn't have a battery. There is no sign of life whether I turn the key to the left (glow plugs) or the right (try to start tractor).

Later, I realized at least one mistake I had made -- I forgot to zip-tie down the positive cable, which was kind of free under the hood. While the tractor was in motion bouncing around, if this positive cable made any contact with the chassis (negative) it might cause a short circuit and blow a fuse, right? So I zip tied the positive cable/clamp to the handle of the battery, so it doesn't move now. I also tested the battery and found 12.8V, so it's not the battery.

So having closed the barn door after the horses had bolted, I replaced all the blade fuses (this is the 4x4 version of the tractor) with brand new ones, since they were all old and stored outdoors, and you never know if they're corroded internally. So I eliminated that possibility.

I also discovered the existence and location of the "Fusable Link" 40A fuse. I removed it, cleaned it, and tested it for continuity. IT PASSED. So I put it back. But still no life when I do anything with the ignition key.

It can't be any safety feature, because I should *at least* be getting lights on the dash when I try to activate the glow plugs.

Is it some wiring that just decided to "open" the circuit the rest of the way while I was driving? Is it definitely an electrical problem? Keep in mind the tractor died while it was running. I never had this happen before.

I'd love to have my tractor working again. Thanks in advance for any help,

Matthew

First thought was Likely blew a fusible link or slow blow fuse. Have changed my mind.

Post some photos of what you did with the battery, the fusible link or 40 amp fuse you found and where on the tractor it is located.

I would start by removing and thoroughly cleaning the point where the negative battery cable attaches to the frame or engine.

With your various "mickey mouse," connections, one might have failed due to the sudden high amperage current when the + bat cable shorted.

If you have an owners manual which includes a wiring diagram, post it here.

If you are correct and the short circuit took place with the + battery cable, then no fuse or fusible link would have see the massive current flow.

Use your meter to trace the voltage from the battery. Sooner or later you'll find the problem.
