"New" 1250 with troubles
 
4 Attachment(s)
Well I did it again! Couldn't let em' put the old dog down, so I rescued another one from death. Wonder what I was thinking!!
So I now need the advise of the experts on a problem I've got with it. It turns over very well with a new battery, but I've got no spark. Changed the normal things, put on a coil from another tractor, condenser, new spark plug, and a plug wire from another tractor. Nothing. Also cleaned the points, nothing!
What am I missing here? Wires are all good, nothing out of place.
HELP!!!

Getting 12V to the coil? While cranking?

Yes it is.

Is the ground strap from engine to frame intact?

Hey Matt, I gave it a quick look around the sides, front and back and see nothing. Would it be underneath? If so I'll have to raise it up tomorrow to look.
Think that could be the trouble?

Matt G. 06-25-2011 11:27 PM
There should be a fairly heavy ground strap from the right front corner of the engine to one of the right side grille casting bolts. That might be the problem because the engine isn't grounded through the engine mounts.

Then again, that might have been a stupid question...if the starter cranks over, it's grounded somehow.

Is your new spark plug for sure good?

I took it out of one of the other tractors that run. Not technically "new" didn't want to run 4 miles for a new one. So you're thinking the ground would'nt be the problem? What about the regulator? I've never worked on one of these, newer ones before. Isn't that the little box with the three wires going to it just to the left and back of the coil.

I had to make sure so I looked ast your pics again and the tins are in good shape! Got side panels? Even the rust didn't look to bad. You'll get it figured out!

Todd, your collection keeps growing! :ThumbsUp:

No side panels, no deck, just tractor. It has 1050 tires, did they come stocked with them?

Yep:beer2:

The rectifier doesn't have anything to do with the spark, so that ain't it.

I just remembered something...check the wire from the coil to the points. If that breaks, you won't have spark. I think I had to replace that on the K321 I put in my loader tractor so it would run.

Donovan M. 06-26-2011 09:13 AM
there is no regulator on the ql's

My mistake, "rectifier" I didn't know if that would have anything to do with spark or not.
Matt, I'll check the wire, but I looked at all the wires and saw nothing out of place, but I'll double check.
Thanks

Checked the wire, it seems to be fine. What is the fuse in the dash for? Checked it and it's good, but even when I took it out the tractor still turned over, or does that have nothing to do with it turning, and or starting the tractor?

ih nut 06-26-2011 11:02 AM
the fuses should be for lights and another one for the electric clutch I do believe.
thanks

zippy1 06-26-2011 11:17 AM
Don't have lights!!

Try wiggling the plug on the back of the key switch. I have a 1450 that sometimes has no fire and the plug is corroded. I took it apart and cleaned it , and it is better , but i need to replace the switch and the plug.

All good ideas, I replaced the ignition switch, it was shot. When I got it home it wouldn't turn over, found the switch was bad, as I had it apart I cleaned up the plug, so I'm thinking that's not it.
I've got power to the points, just checked that, could it be the points?

The factory Quietline engine ground 'strap' is a short yellow wire coming from between the right side firewall bolt and the frame (the terminal is sandwiched between the bottom of the sheetmetal firewall and the 'spud' on the frame for the firewall's attachment bolt)-to one of the regulator/rectifier bolts >or one of the bolts that hold the flywheel shroud on...I've seen them in both places.

It is possible for the engine to find a ground through the throttle and choke cables (if the short yellow wire is missing) . This causes intermittent electrical gremlins, and most times the throttle and choke cables will get wickedly HOT!!
Hey Bill, checked everything as you mentioned, parts are from my 122 that work fine. I checked for power with test light at the points wit hswitch on. I don't have a meter to use, just a light.
I also don't see any ground strap what so ever, think I should fab one up? Just to safe.
The points are the one's that were in the tractor when I brought it home, I did use some sand paper on them, to clean em' up.
I'm going out to cut the lawn and cool off, this thing is driving me crazy, and God knows it wouldn't be a real far trip:biggrin2:
Thanks, I'll check back in about two hours, by then you all should have it figured out:ROTF2:

zippy1 06-26-2011 05:44 PM
1250 LIVES again thanks to you
 
Well it runs, not real pretty, but it runs.
Found where the ground wire should have been, the PO must have needed a short wire for something and removed it:angry:
Made up a new one and cleaned up the attachment points and away it went, so to speak.
Well I sure do appriciate everyone chimming in with your suggestions, really helped alot.
If I wasn't so far away, the cold ones would be on me:beerchug:
Thanks again!!!

That's awesome, Todd! :IH Trusted Hand:

Amazing how a tiny little ground wire can throw a monkey wrench into the whole works and drive you crazy, LOL. I am glad to hear it is now making some noise. :beerchug:

Thats great!

Yup, that's for sure. It not only makes noise, it blows smoke pretty good to:biggrin2:

juniors1282 06-26-2011 10:11 PM
