Alive, Dead, Alive

Yesterday I fired up my DK45 fine, then needed to turn it off to get the pressure off my front remote hydraulic hoses so I could relocate the fittings. When I went to restart, I got nothing...not even lights on the dash. I looked at the fuses and relays and couldn't see any obvious issues. Checked battery terminals: tight and not corroded. I tried the key again (nothing) and when I turned it to the OFF position, I heard a rapid clicking sound coming from the fuse box (or thereabouts); this sound continued even when I completely removed the key from the ignition. Of course, I had already bolted the cover back on the box and by the time I got it back off, the sound had stopped.
Nothing was hot, melted, burned or othewise looking (or smelling) unusual or damaged in the fuse compartment (including the relays), so I tried the ignition again. Guess what? All normal! All dash lights worked, and the engine started right up and ran fine while I did nearly an hour of tractor time.

Any ideas what this is? I really don't want a problem like this to reappear in, say, the middle of a February blizzard!

Pretty much everything runs through the key switch, and they have been problematic; so that'd be my first guess. But battery cables (under the insulation) have also been a problem. If it happens again, see if the emergency flashers still work when all else is dead; that would be a clue.

So - Thinking out of the box , where you not setting in the seat ( no start ) .Then setting in the seat ( started ) ? Seat switch might do that ?

All electric seemed dead, including the flashers. I was sitting in the seat on all tries. I suspect the ignition switch itself, too, but I'm still confused by the rapid clicking sound that came from the fuse box...even when the key wasn't in the ignition.
I didn't really DO anything to fix it, but it started working again, so I'm good for now. Still, not knowing the cause doesn't fill me with confidence about its reliability for the upcoming winter season.

Go back to the battery and check inside the positive cable plastic cover. It can look tight where the bolt crimps it to the post, but look below by the plastic sleeve. Under the bolt you tighten is a thin copper band around the lower portion of the terminal post. I just had this problem and discovered the copper terminal ring against the plastic housing had separated below where you tighten it on.

Not sayin this is your problem, but another gotcha is the slo-blo fuse in the power tap that goes to the key switch. If that pops you get these exact symptoms (except for the intermittent fault). It is buried inside the wire harness and covered with PVC electrical tape. At least mine was. It's near the starter. I had to order one from amazon cz the local auto parts places don't carry them.

Never known a blown fuse to reset....

Huh? Now how on earth did you construe that from what I wrote? Curious. Clearly, my friend, the fuse I mention is not the issue.

This model does not have a seat switch. Well hang on... your model is listed as a Dk45SC.. I first thought this was an DK45SE... I am not sure what a Dk45SC is, so I cant say for sure about the seat switch.

No seat switch on the DK line that I am aware of!
