Trouble Starting, no 'click'

[dcnick]

I recently experienced twice now when turning the key to activate the glow plugs before starting, nothing happens, no 'click' indicating that the plugs are heating up. And if I turn to engage the starter, nothing. I then discovered that if I quickly turn the key (either way) a number of times, it eventually catches (glow plugs heat up and/or starter engages).
Has anyone else experienced this and if so, do you have a remedy?

It really helps if you tell us exactly what piece of equipment your having this issue with.

It is a pricey switch to replace.

So I would remove the key switch from the bonnet and disconnect the connector to it. Then bench test the switch with a light bulb test to see if the wafer is malfunctioning inside the switch. See the exploded parts diagram for the switch. Wiring diagram is in the Workshop Manual (WSM). If the switch checks OK, then test from the wiring harness connector to check out wiring from switch connector to starter relay and glow plug circuit.

First off, I thought that the equipment was displayed on my listing under "Equipment"?
I'm having the trouble with my 2014 L4600.

Thanks for the suggestion Jim L. I'll give that a shot.

Second off: Just because you have a model listed doesn't mean that's what your actually working on.
And I'll ask one more time, tell us exactly what you're working on.

The L4600 comes in 3 versions and the wiring and switches might or might not be the same between sub models, I don't like giving guesses based on a model guess!

My apologies. It's a L4600HST with LA764 loader

I had similar symptoms on my BX2350. First indication was no "click" when the key is turned to the ON position. Turns out that at least on this machine the click is from the fuel shut off solenoid. I manually worked the solenoid shaft in and out a few times to get it unstuck. It's been fine ever since.

Edit: Sorry, I missed the part where you said it wouldn't crank. In my situation, it would crank but not fire.

Turn the key to start see if you have headlight, flashers, dash indicators and such?
Turn the key to crank and hold it there and while holding it move the HST pedal back and forth, then do the same for the pto engagement lever.

Tell us what you get.

I’m so happy that I installed an Ammeter years ago. I can see electrical “draw” when any item is activated…. or not….

My BX23S pulled the same stunt a couple winters back, intermittent click then nothin, then fine. Turned out to be a crusty ground at the block. Wire brushed the lug n bolt, hasnt missed since. Id check that n the battery posts before pullin the switch apart tbh, 5 min job.

Thanks Wolfman. Will do when it happens again. At this point, the lights, turn signals, etc. all worked with key on when I had the problem.

To expand on my earlier post… When i bought my “lightly used” tractor…. it LOOKED great! It RAN great! It STARTED great! ….



….for a week.

THEN I discovered why it was sold to me with a Brand-New Battery!
(and why the seller had disabled the idiot-lamp)

I guess he knew he’d be selling it to an idiot.

the ALTernator was DEAD! … and Kubota wanted $600 Just for a replacement PART. (labor extra)


After I replaced the alternator…. (D.B. Electrical/Amazon/$80)…….I complimented the Idiot-Light with an AMMETER … So I now SEE a 20A DIS-charge when those glow-plugs activate as I turn the key to “start”…. and I SEE the 40A CHARGE immediately AFTER START…. telling me things are WORKING PROPERLY.

Simple answer. $20 for a Harbor Freight gauge and a few minutes installation.

That was 8 years ago.
