BX22 stops running when key is released

[katana]

Starts but as soon as the key is released she dies. The battery is fully charged. I've replaced the stop solenoid, but that didn't do anything. All the fuses are fine. No obvious wire issues. What else should I check/test before throwing a new ignition switch at it?

 

[ruffdog]

If the stop solenoid is a 2 stage pull/hold design, maybe the hold circuit is not providing power.??? Did you test power at the solenoid?

 

[katana]

I don't appear to have any voltage at the connector with the key in the on position. Need to find some jumper wires to test the solenoid.

Fairly odd that it starts yet won't keep running. Starting in the first place clears all the safety interlocks of guilt. Hang in there for a while before replacing the ignition switch -- that's costly I expect. Fuses? Did this problem just suddenly happen one day pout of the clear blue with no events or issues leading up to it?

It happened after I had issues with the transmission safety switch sticking. At that point, it wouldn't start at all, but I got the switch cleaned, lubed, and working, but I now have the current issue.

If your inj pump stop solenoid has 3 wires, u have a relay that switches over from “start” to “hold”.,
If it’s a 2 wire solenoid, I would suspect the key switch..
Good luck

I have an old BX2200 that has that problem on occasion. Ordered and installed a new solenoid and it would not work at all. Original solenoid works 95% of the time. Lesson do not assume the the new solenoid is good.....

It has three wires. The only relay listed for my model is part of an alternator option that I don't have.

Yeah, I am going to get some wire today to bench test with - will check both the old and new solenoid.

Black is ground..-
White is pull in..
Red is hold..
If your tester doesn’t have the amps to pull it in, it’s ok to apply a little pressure to the rod..to get it to snap in..
Next swap the white over to red, leave the black as ground..
Push in on the rod w the tester on the red and it should hold..
Good luck

Thanks for that. I tested both of them, and they are fine - I wish I had done that to begin with.

My grasshopper mower that has a Kubota diesel did the same thing. It ended up being a bad key switch that wasn’t putting out voltage in the run position.

Thanks. I have one on order.

No luck with the new key switch either. I am guessing wiring at this point - am I missing any other possibilities?

 

[thepumpguysc]

That sux.!!
Can u follow the wires thru the harness FROM the solenoid.?? They gotta go to some relays..
I was ALWAYS told that the pull in came right from the starter, do to the hi amperage required to “pull in” the rod.. THEN it switches over to low amperage thru a relay..
I’m mearly repeating what I’ve been told, I have no actual experience tracing it down.. good luck

When I had this issue a few years ago with my BX22, the fuses seemed good and tested good, but one wasn't. I don't know if the setup is the same between the first generation BX22 and your BX23, but the fuse that was the issue was not one in the fuse panel under the steering wheel, but one of the two on a small pigtail down near the frame, right side if I recall.

Can you get a wiring flow chart from your dealer? Without knowing what goes where and why, you`re just chasing chickens at this point.

Did you check the diode?

 

[katana]

I am not sure what actually fixed it, in the end. Perhaps I just jiggled something that will rear its head again down the road. I traced the wires back to the firewall and then up into the dash. I followed them blindly, just by touch, and found that there was a loose connection to one of the dash switches. I clicked it back in and suddenly had voltage back at the connector and was back in business.

Oh those dang awful pesky connectors.
