I was having some troubles with my BX2200. !st it wouldn't charge woth a lick. and, it all of a sudden didn't want to start and stay running. I found my problems (I think) and wanted to pass some info along.
First, the starting problem. I went through it up and down and all around. It would start and only run with the key held in the start mode. As soon as you let the tension off the starter key it would die. I figured it was a fuse. I got the test light and all fuses were good. Then I started looking. I figured a bad key switch or a bad fuel solenoid shutoff. The local dealers didn't have either one. For what ever reason I decide to change all the fuses. The 1st 20A fuse for the key start was fine, i tested it with my mini meeter but when I put the new fuse in it fired up like a new machine. I swapped the fuse back and it wouldn't run again. I have a fuse from the twilight zone!
As far as the charging problem. My battery light never came on since I got this machine. It is supposed to come opn with the temp light with the key on and engine off. I took the alternator off and brought it to the local auto electric guy at Bear Hill Electric here in Bethany. He took it apart and said it was fine. He blew the dust out and put it back together. He said it was either a fuse or the regulator. I went back home, rebolted the alternator, hooked the battery back up and BAM the light was on with the key! I fired it up and it is putting out 14V at full speed. I took the alternator wires off and put them back on to check them and they were fine. I spoke to one ghuy who said these newer reghulators have a chip in them and if they sense a low battery or short or any indication of a problem, they go into a safe mode and shut off the power from the alternator. This guy works on boat diesels and wasn't sure if the kubota tractors have the same new tech. He said they reset when you disconnect the battery and re attach the cables. The previous owner I got this from hadn't run it for a while and told me he needed to jump it. I have a strange feeling he crossed the jumpers and the regulator went into "safe" mode if this is the type on there.
All I know is the dealer and local tractor shops all told me they have yet to see any electrical problems on the newer or even the older bx's. I think this was all caused by the previous owner and this may be valuable info to some of you should you have a charging problem. Try disconnecting the battery and it may work like it did for me. The only other thing I think may have been the cause, but unlikey, is the alternator lost it's ground. It is grounded from the bolts on the brackets. Maybe it was installed when damp and built up corrosion. I think this is unlikely but who knows. Either way if you run into problems don't spend the 169 bucks on a new alternator right away...Jim

I had some of those twilight fuses on my old Ford. The lighting circuits were intermittent. I noticed the problem when I accidentally tested both sides of a fuse holder and noticed it had voltage on only one side. The fuse itself tested good. Burnished the holder contacts and fuse ends and it hasn't done it since.
My old Ford also had factory paint in the alternator output terminal 15 years later. I believe that cleaning off shortened up the recharge times. All sorts of twilight things can happen. Makes life interesting--maybe. ....
