682 Not cranking

wagscub · #1 01-14-2014, 05:26 PM

I've got a recently purchased 682.
Serial Number: 2050593u675385

I purchased it in running condition. Plowed for 2-3 hours with it. Ran great, smokes a little, but beside the point.

Went to start it the next snowfall. Clicked but, No crank. I haven't had to deal with much mechanical stuff in 15 years or so....so the brain is little rusty in those area still.

I tried jumping the solenoid in the process and fear I may have burned something up along the way.....

Since then, I have replaced the solenoid with what was similar on it. I'm quite certain it was not original. Original has 3 posts, right? This one had 4. I matched it up at the auto parts store and wired it the same as before.

Still no crank. I don't a click either.

I know there a couple safety switches. Would it still crank and not fire? or would that produce a no crank scenario?

Where do I start testing my voltages?
I've got 12.5 volts on the battery.

So after you replaced the solenoid, what happens when you turn the key? If it still clicks (or you hear the starter spinning but not engaging) chances are it's your starter (or the voltages/power getting to it), or at least that's where I'd start looking. My 682 did the same exact thing and it turned out to be a old/bad battery. Replaced it and it's much, much better. I will say, though, that I've heard one too many times that the starter on the KT-17 is a weak point so keep that in mind. I'd try jumping the tractor with another battery or tractor and see if the starter kicks when you do that. If it does, your battery is most likely the culprit. After that, I'd get it running and check the charging system, I believe when running it should be around 13.6v.

Another couple things to check are grounds. So many problems are caused by poor grounds. I'd at the very least remove all your ground connections one by one and clean them very well. Even if that's not it, it could not hurt. As for safety switches, you can always bypass them for testing purposes but mentioning how here seems to be frowned upon I won't go there but it is very easy to do

What I want to know is why do you think you burned up your solenoid?

Edit: I reread your post. If it no longer clicks after the new solenoid, check your safety switches and just for sh!t's and giggles, when you try cranking it next time, make sure the brake peddle is depressed and wiggle the PTO switch, sometimes those can go bad or have a bad contact on them that causes a tractor not to crank. If a safety switch or PTO switch are causing a problem then yes, it would cause a no crank scenario. Either way, clicking of starter usually means it's not getting enough juice to crank the engine. Jump/try a different battery and double and triple check all power and ground connections and switches.

I currently get no clicking whatsoever.

I really wasn't sure that burned up the solenoid. I seem to remember from my youth that dad and I would end up switching these from time to time. I simply started there and redid a couple of the connections to get a better contact.

I will go back to the grounds and clean those up for good measure.

What's the likelihood that the ignition switch has gone bad? I do get the lights on, but nothing beyond that.

Thanks for your input. I know I'll eventually get to the bottom of it....I was kinda hoping there was some quirky things about these tractors that I would know about.

That does sound more like a safety interlock switch issue, although weak grounds can be a problem, too.

Try "jiggling" the PTO switch! too. Any fault in the safety circuit will prevent cranking.

I have pulled up and copied the wiring diagram from the tech section of the forum....a huge thank you!

The safety switches that I see are:
Seat
PTO
are there others?

Where is the PTO safety located?

The seat switch is the safety switch for the PTO. The PTO switch has to be off for the tractor to start, but you don't have to be in the seat. The seat switch is only for when the PTO is on. But the starting circuit goes through the PTO switch in the off position. There is a switch on the clutch/brake pedal. It has to be pressed for the tractor to start.

Hope you can get the electrical problem figured out! Sorry I'm not much help, but, at least you know you have a nice running 682. I'm certain the group can help, and of course there is a trouble shooting section in the operators manual found in the tec.section. Chances are if a switch or amp gauge goes bad, then the whole works shuts down.

Good luck!

Thanks, Jimbob! You made my day, and lowered my blood pressure. I've been having trouble with my 1250, and did a little wiggle on the PTO switch and it started right up. Bring on the snow!

Here is the IH 682/782 Start Circuit Diagram. Assuming there is power at the Ignition Switch, then it goes to the PTO Switch (in off position) then the Brake Pedal Safety Switch (has to be depressed) then to the Starter Solenoid.

I see you're from Illinois, where about are you if you don't mind me asking.
