Electrical issue

[Rollcenter]

With key on, check voltage at the "I" terminal of the switch (red wire with white stripe). It should be same voltage as power into the switch on the solid red wire. If no voltage or you see a drop in voltage, then suspect switch problem. This circuit supplies power to the fuse panel, then to the OCU, & Switched Power relay through Red w/blu stripe wires, and from switched power relay to the dash on red w/blk wire.
All of the components (OCU, relays, dash panel, & timer control) all have smaller black ground wires going to frame. Be sure to check any or all of these to see if ground connection is loose somewhere.

I will certainly check that.

Does that explain the horn not working since this happened? Should I be able to "jump" across on the switch the incoming hot to other wires and at least see if I can get engine to turn over?

I'm not sure what you mean by turning switch backwards.

I don't know how similar they are, but here's a link to a CK20 schematic:

If yours is like this, the key switch, the fuse, and the clutch switch are the only things upstream of the starter relay. The flasher feed doesn't go through the key switch. But this schematic is for an older model without the fancy electronic instrument panel. If you do have the newer electronic instrument panel, check the groind lead as mentioned ny SSdoxie.

Try another battery just to eliminate it.
My wifes Mail car, 06 Jeep wrangler had a similar issue.
It always started fine even at 0 and below. She turned it off while at a bank of boxes and no star,t no gauges, lights, nothing.

I went down there with a voltmeter expecting to find a bad wire or something.
Checked battery 13 volts, 13 volts at the starter soleniod, no bad, burnt wires.

No lights at all, gauges were all kind of wacky doing weird stuff when you turned the key on.

Shorted the starter solenoid, nothing, check voltage 13 volts.

It all didn't make any sense, so I checked battery voltage one more time, 13 volts, I then laid a wrench accross the posts on the battery nothing, no spark, no arc, nothing check voltage, 13 volts.

So I went and bought a battery and all was good.

If you have one to throw in it you might give it a shot.

While you're at it, NEVER dead short a battery by placing any metal object across the posts - NEVER!
That is possibly the worst advice anyone could ever give another person about how to test a battery.

If you want to do a proper load test on a questionable battery- remove it from the tractor and have a competent automotive facility test it for you. The other way risks possible battery explosion, and acid in your face /hands, etc.

Hey Spock, You ever mount your plate I sent ya?

Wow, I can only emphasize what CM says, that is the craziest thing you could ever do, just don't do it. There's a lot of energy in a battery, even a bad one.

Hijack much?
Haven't had time to mess with it, Scotty

Commander out

I wasn't giving advice on how to test a battery.
I was out in the middle of no where, I did what I needed to do.
I did turn my head.

Lol! I hav not ever tested a battery this way but i have, on occasion, turned my head away from things i wasnt sure about much like you did. Ha.

I seriously doubt you've ever been around an exploding battery. Most people haven't. Having owned a foreign auto shop for over ten years I was unfortunate enough to have a guy with a stakeside truck pull into my shop drive and tell me his alternator wasn't working and he had replaced the battery with one that was working. While we were having the discussion in my shop bay his truck battery exploded. It was a never forget the sound or level of fright from the witnessing of something so powerful I was glad to have been in my shop and not anywhere near his truck moment. He was to deliver me some wood for winter, and fortunately for him it exploded when it did and not when he was messing with the battery, shortly before he arrived at my shop. It turned out the alternator was wide open- the voltage regulator was not working, and the battery was taking back over 17Volts.

You may not think you were giving advice- but you did explain what you did to fix your wife's truck. A novice could easily mistake what you did as a way to test their battery and find acid and battery casing in their face in no time at all.
And, BTW, you're new here so I'll cut you some slack- but something like what you stated is dead wrong and is in no way funny or justifiable.
What you could have done different in your, in the middle of nowhere, scenario is use the volt meter to see if there was a voltage drop when you turned the key to crank.

The 'wierd' acting gauges would also indicate a likely flakey or near dead battery if you had known what to look for .
What you had to do could easily render someone else with a real serious accident, as a result of following your non-advice. Think about it and how lucky you are to not be blind or worse.
