Hey all, Looking for a wiring diagram for my 2004 BX23 MLB. Can't download the wiring diagram for some reason. Looking for the flasher relay. Switch got wet. Thank you in advance for any help.

See if this material helps you.

The actual wiring diagram is not too clear. I got the pdf from a dealer who downloaded it from Kubota's webn site but for some reason the wiring diagram for the BX23 is drawn in a way that makes it hard to both see and follow.

Not sure about a BX23, but when the switch got wet on my BX2230 the flashers worked weirdly or not at all. I pulled the switch, put it in the oven on low for an hour, reinstalled it and it worked okay. I also sprayed some CorrosionX into it to prevent any corrosion if water did grt into it again.
I have no idea why Kubota would put a switch that is not waterproof on a tractor that is likely to get rained on or otherwise get the turn signal switch wet. The flasher is an electronic unit that is confused be the small amount of current that can be passed by water that gets into the switch.

So here is what happened. I just bought this tractor. All switches were missing replaced them and everything worked fine until it rained (didn't know they were not waterproof). they blinked one time then stopped and could hear a clicking somewhere under the dash then it would stop. bought a waterproof switch and same thing is happening.

Dave, the Switch test page you put up is actually for a BX23S which has a combination switch where a BX23 has 3 rocker switches for Hazard, Turn, and Lights.

Sounds like some water got in to a connection. Possibly a switch. Water + time = corrosion. I'd get some CRC contact cleaner and just start following wires and cleaning things up. Start with the bulb sockets. Take them out, inspect them, clean them, add a dab of dielectric grease and then follow the wires to the next connection. Repeat all the way to the battery. Make sure you get the ground side of the circuit, too.

There had to be a reason all the switches were missing. Maybe the PO was having similar problems and started to replace them, but didn't finish the job.
