Points ingition condenser modern eqv

[Mick Oz]

I have just installed an ignition tune up kit on my TEd20
First, I have never seen this tractor run. It was a seized rusted project when I got it.
So the engine now turns by hand crank and on the electric starter.
The only test I know for an electric coil is disconect the small wire from coil to distributor at the distributor end and also the HT lead from the distibutor.
Place the HT close to an earth.
Take the small wire and rub it along a stud or bolt threads that are earthed. This bumping from thread to thread earths and insulates the small wire, like circuit open closed open closed. So each time it is not touching a thread on the stud the Coil will fire a spark through the HT lead and I can see that.
So I believe the coil works.
I have checked the points closed I have 12v between each side and earth. Open I have 12v one side 0v the other.
So I think they are not earthed and installed correctly. Wothout the cap in place I can watch them open and close as the engine spins on the starter, no spark jumping that I can see, even in the dark.
But I have no spark at the plugs, I will dig out an old in line spark tester tomorrow and have a lash with that, but my usual suspect even with new parts is the condenser.
So after ALL THAT , can you tell me a modern part number for an off the shelf condenser that may be available from a local auto parts store, rather than waitin another week or more for an online source to post me a IGK5904 which is the listed condenser for TEA TED.

Have you + or - to earth?

The tractor came wired as - earth with the negative side of of the coil conected by the small wire to distributor.

With someone able to explain very slowly I was able to work out that I had a poor connection through the distributor wall to the points.
That is now sorted and I have spark at all 4 plugs.
Next job the carby.

I'm glad you found the problem. That's a clever idea to rub the coil to distributor wire along a threaded bolt to make the coil spark. I'm pretty tired of having to file and set the ignition points on my Ferguson TO-35. The points seem to develop a thin layer of oxidation on the contact surfaces if I don't use the tractor often.
I'm about ready to buy an electronic module to replace the points , even though I have a disliking for replacing stock parts with " modern" electronic parts.
Do new points have the same oxidation problem , or is it the filing that exposes an oxidation prone metal ?
By the way, I've found over the years that a new condenser has about the same reliability as a used condenser ; that is, either can fail without warning.

I had a TED20 back around 2008 and I installed a Pertronix electronic ignition kit on that. I did however get a dud part in the kit. But after a phone call then some tests they replaced one of the parts for me and the TED never missed a beat after that.
