BX1500 won’t start

[Robobike]

Last week I went to start the 2004 BX1500 and it cranked as normal and started to fire up and then just quit. I tried again, turned the key and the normal fuel pump clicking happened, but when is got to the glow plug position the glow light did not illuminate and the other lights seemed to dim. I turned the key back to the off position and a very staring buzzing came from a relay under the dash and continued for about 5 seconds then stopped.

I had the battery thermals cleaned and the battery load tested and it’s fine. I ran a jump wire from the battery positive to the spade connection on the starter solenoid and got no reaction from the starter. I also tested for voltage on the spade wire while sitting on the seat and turning the key and only saw a voltage of about 1.5V.

I suspect there is a battery connection issue but not sure where to start looking. I’m somewhat new to Kubota.

Thanks, Rob

Start by removing and cleaning the Negative connection at the tractor side of the cable.

How did you load test the battery? It really sounds like the battery is bad. How old is the battery? Did you try jump starting it? If it starts by jump starting it, the battery is the problem.

Thanks. I did clean the terminals when I pulled battery for testing. Load test was done at my local parts store. I will try to jump it tomorrow. Rob

Battery is a 2013 but has been on a tender most of its life. I will also clean the negative battery cable at the tractor.

Cables can also be bad. After you clean the negative connection, do a load test of your own. Put a meter on the starter and see what your voltage looks like when you try to crank it. You might need a helper to turn the key while you watch your meter. Let us know what you find out.
