Suspect condenser? Even when new?

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.

Mate got a muti meter? google testing a coil. roughly i think its about3 to 4 ohms across the small terminals and Kilo ohm across the HT and small terminals... It has the correct valves on the manual..

12 v across points good, do you get a spark across the points when you open close them with screw driver?

I would guess a stuffed coil, got another for testing?

I do have a multi meter I will try your test tomorrow. No spark at points.
Do you know if any other coil will suit this application as an online one will take the best part of a week.

any coil out of an old holden or ford should do it.

I bought one from super cheap about $40...

That sounds like a good option.
But how do I know which coil to buy? How old a holden or ford?

Find the 'oldest' condenser you can muster up. A few years ago, nearly every brand new condenser, all from the same sweat shop in southern China? AALLL were bad. Should have been a class action suit, but who do you sue?
We started collecting ones from the 1990's, which were probably all made in Mexico- but they fired up! More likely that if your coil test good.

"disconect the small wire from coil to distributor at the distributor"

By disconnecting wire at side of distributor you are eliminating points and condenser. Reconnect the wire and do same test using a wood dowel to open and close points arcing center lead from coil to frame. With condenser added to equation you should see a stronger spark. If so the condenser is working.

Check for rust and corrosion in bottom of big coil center connection. Common on old coils

Thankyou, I will get back to checking.

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.
