BX23 solenoid location

[Volfandt]

So the solenoid opening back up is the click I hear a few seconds after shut-down?

Yep. thats the solenoid returning to it's "un-energized" state. Which is also the indication that the 10 to 15 sec's of 12v thats applied to the solenoid from the timer relay when the key is turned off and/or a safety switch trips, has been removed.

If you unplug the solenoid's connector, so you can't hear it "slam" back, you can hear the faint sound of the timer relay clicking.

I printed off the wireing schematic and will study it some when I get alittle extra time this evening. A quick glance seems to show either some misprints and/or incomplete details.
Some of these model will run without the solenoid installed, I'm now curious if thats the case with ours.
We'll cypher it out

re:solenoidwiring questions; my 2910 i was having trouble starting and keeping running absolutely runs fine w/o the solenoid. Just put a cover plate using same mtg hdw. and kill it with kill lever on front of pump. flatfenderguy

Although I read 12 volts on the pair of wires that feed the solenoid, it doesn't energize the solenoid. I put 2 amps and 12 volts from my charger on the "in situ" solenoid and i can hear the unit pop out and then in . Something is indeed awry. Tried beating on the timer relay to no avail.Guess I'll try to replace the relay. Also, when the problem 1st began, , the engine would shut down a few seconds after the key was put in the off position, then this deteriorated until it would not shut off at all. Larry

Sounds like a wiring problem to me. Does it get a full 12 volts to the coil when on the tractor. You might show 12 volt with out the coil load, but most important is the voltage to the coil when installed in the circut.

I'll check the juice to the solenoid while its hooked up. Thanks. By the way, I noticed that the timer solenoid( it its Denso part 061700 3770 black box with 4 contacts and silver label) Label says "important keep mounting in the direction shown right" with an arrow to the top. There are 2 plastic clips molded into the to of the case which holds onto a bracket in the correct position. Mine are broken so the relay hangs upside down. The definitely is no clicking going on.
What damage cold happen by it hanging upside down? I guess I'll replace it. Larry

I don't know about damage, but if it's a mercury switched relay, it won't work upside down.

EUREKA!! I replaced the relay, called a timer key stop, kubota # T0070 31410,and lo and behold, everything works the way it should. The seat saftey switches and the solenoid work again. I feel much better being able to shut the unit down from the seat. thanks for the help, Larry in western Mass.

Great work guys.

I have to share my experience regarding the above quote.
When I am creeping the tractor with the hst pedal and go too far and hit the shutdown switch it does not activate the timer.
If I release the pedal as soon as I hear the tractor stumble then it will continue to run. I haven't tried standing up with the pto engaged to see if it activates the timer but maybe this weekend.

Rusty4242, great, glad you got it fixed. I believe thats the 1st case of a bad timer relay posted here. Course I could have missed one if it was
Hate to say it but your tractor failure helped me understand how mine works, I guess I should say both thanks and sorry 'bout that

Berniep, if you've got a multimeter you can test your safety switches by unplugging the stop solenoid connector and plugging your meter into the connector, then do your tests with just the key switch on, simulating a run condition, It'll save you fuel $$$'s and wear and tear on your engine

[Rusty4242]

No.The click is from the timer relay under the dash which cuts the current to the solenoid. I suppose the solenoid should retract at the same time, so maybe what we hear are both sounds together. Larry
