BX no start issue

   / BX no start issue #11  
The HST switch only moves a little to be out of adjustment, Try about 3 layers of duck tape between switch and rod to see if it works for you, It did for me.

Hi again,

The relay mentioned above is an addition and does not exist in your tractor at the moment, so you will not find it. If you check that thread referenced above you will find a mention of the place where I bought my low-voltage relay. It might be called Hartville tools or something similar.

But before you buy anything you probably do want to verify that the problem you're having IS with contacts in the safety circuit. I'm in Japan right now and cannot look at my tractor or my workshop manual. But if you look at your starter, I think you will see a small wire going to the starter solenoid. If there is only one wire going to the starter solenoid, then if you applied voltage from your battery to the terminal that wire goes to, it should activate the starter.

It would probably be best to have a switch in the wire between the battery terminal and the starter solenoid terminal, then you could apply and immediately remove voltage, and not have to deal with the spark you would likely get if you touched the wire directly to the starter solenoid terminal.

If you do this, you don't even have to start the engine, you only have to hear the starter start to turn it over to prove that your issues in the safety circuit contacts.

If you do try this, make sure the tractor is in neutral and that the parking brake is firmly set, just to be on the safe side.

Checking voltage with a test lamp can be confusing sometimes because there may be some voltage there, but not enough to cause the lamp to light. A voltmeter would be a better choice if you had one, but perhaps you don't.

I remember other threads here on TBN that address this issue and have specifics about the interposing relay, including part numbers and possible sources. The one I got was for John Deere and required me to splice a couple wires. I have read there is one specific for Kubota that is plug and play, but that was not the one I used. Perhaps someone will read this read and give you specific details.

Best thing you can do at this point is confirm that the problem is in the safety circuit contacts. Are you getting the "click click" sound when you try to start the engine? If so chances are pretty good that It is voltage drop within the safety circuit that's your problem. If there is no click click sound, then the problem could still be in the safety circuit, but perhaps a broken wire or a failed contact. If this is the case then the relay mentioned would not fix your problem.

Hope this helps!

Thanks Henro!
I did check to see if the little wire on the starter received voltage but it did not but I can jump it tomorrow and see what happens.
I see your point on the test light, I do have a volt meter but to be honest it was over the house and I was in the middle of working on it so I didn't walk over and grab it - I will!

Seeing you are in Japan, if you happen to see Mr Kubota, ask him his thoughts for me.... LOL

Update - Thanks again Henro
I checked everything again and nothing changed.
I washed the machine to get everything clean and easier to work on then jumped the starter and she fired right up. Hooked up my tiller and get that job done at least.
I do get the fuel pump activating and when I shut the key off I get the normal delay and then that "clunk" of the fuel system reseting
At the starter I am getting 0 on the small wire when I hit the key so no electric is making it that far.
Seems it has to be a safety switch. Pretty sure it is not related tot he seat (that has been bypassed since new and I even hooked it back up and had no change.
For some reason I am thinking that PTO switch but still not sure.
I also ordered the workshop manual today (also figured out my BX is a few months out of warranty - was only 2 years when I bought mine - bummer)
If anyone has an electrical diagram for a BX25 they could post or send me it would be greatly appreciated!

Just went online and ordered 3 new safety switches - $38 shipped.
Figured it is a LOT cheaper than taking it to the dealer (if I am right) if not I guess I am out $38 bucks. Seems like a good gamble. I will let you know what happens when they come in later this week!

following along... sounds like you are on the right track now, Code.

I sure hope so! Looked a little funny with the sides off the tractor today running around tilling the yard. I am adding a standby generator to the house so I trenched the yard to run gas and the feed lines so I had big clumps of dry clay laying all over the place and wanted to till then rake it before it rains and I have a royal mess. Just glad I had the mini to dig with since the BX decided to try going belly up! Oh well, first minor issue at least it is not the motor or pumps!

Yeah... sounds like a cheap and easy fix once you find the buggar!!!

While we are waiting for Code54's switches to arrive, I have a question.

Are all the limit switches exposed on the tractor for easy replacement? I was of the understanding that at least a couple of them were internal and difficult to physically access. At least on my BX2200. So I assumed that using the added low voltage ready was the easiest fix. Maybe not? (I should have looked more closely)

I am away from my tractor for another ten days so at the moment I cannot check myself.

By the way, we were at a friend's house a couple days ago for lunch and a visit, and he introduces us to another friend he invited, and wouldn't you know the guy's name turns out to be Kubota! Did not seem to have any interest in tractors though...:thumbdown:

Well I can't say they are "easy" to get to. The seat ones are easy, PTO not too too bad, the HST is not looking like a fun project. Thinking I am going to pop the connection off the switch and hook the new one up without installing it on the tractor to see which one is bad (just hold the button in, etc to test)

Bummer on Mr Kubota - that could have been a pretty neat meeting.....
