BX2670 Dead Dash, Not Charging

[swampstalker]

My BX2670 cranked up fine yesterday. Started cutting grass and after a few minutes the dash went dead (tach and all). It was running fine so I cut for about 20 minutes and it started loosing power. Like bogging down in grass that wasn't very tall, and when you hit the pedal to go forward or reverse. I stopped cutting and checked the connections to the battery, which looked fine. I then checked the battery voltage, which was at 12.1 volts. I checked it again with the tractor running and it was still 12.1 volts, so it isn't charging.

The tractor isn't even a year old, so it is under warranty, but are there any simple things I can check besides connections that would cause this? Trailering it to the dealer is such a pain, and then I will be without it for a week or two. If it is a simple fix I would rather do it myself.

I am assuming the loss of power is because the battery was getting weak.

Thanks

The engine itself doesn't need electrical power to run, but there is a fuel pump on the bottom of the tractor to feed it fuel.

It seems like quite of bit of your electrical system is dead, so the fuel pump is probably dead too, starving it from fuel. One drawback of not having gravity feed fuel system. But it is nice having the tank under the fenders.

Since it seems lots of electrical stuff is dead, that might be the main fuse either is blown, or just disconnected, loose. Or the key switch that turns everything on is faulty, or an electrical harness connector is disconnected. What ever it is, its a simple problem, the electrical system on the BX is dead simple. Likely you'll be able to fix it yourself.

The battery being only 12.1V when running means that its not charging, should be around 13.5 when charging. The battery is probably still good. If my guesses above are correct, I'm guessing it still has a charge because your not using the battery, it's not powering the system. The fuel pump will run a really long time on battery with no charging, probably days. Since it you lost power after 20 min, the fuel pump is just not running at all.

I forget where the main fuse is, but I think its in the wiring harness on the right side of the engine. Just follow the wires from the batter to the fuse, then the to the fuel pump, and the key switch.

Got it. Thanks. Going to look at that when I get home.

Have a look under the tractor. The wiring to the fuel pump has probably been damaged by the driveshaft or other debris. I have repaired a few for this same complaint. The fuel pump wires are also feeding the alternator's internal regulator, which controls charging and sends the dash a tachometer signal.
