6v ignition coil specs?

Tractor is a JD 40U - taken apart 14 years ago. Ran when parked. Now reassembling....
Everything as per original - 6V, positive ground.
Got no spark by opening and closing the points with my finger.
Have no way to test the condenser.

Coil readings:
primary is 1.4 ohms
secondary is 5020 ohms.

I have the SM for this tractor, but it gives no specs for the coil.
Can anybody tell me if these readings are "good" - or "bad" ?
Or am I barking up the wrong tree?

Thx

The tree might have an animal in the branches. The numbers are good. Put a plastic knife (or other slip of plastic) between the points to keep them open. Turn on
the ignition switch. On the supply side of the coil there should be battery voltage, or a well lit 6v test light. If good, then go on, if not the supply is not
getting volts somewhere between the starter switch, and the coil , including possibly bad switch (test at the switch)
Going on from above. There should be battery voltage, or a pretty good light on the distributor side of the coil. (less bright but OK) If so go on. If no volts, or
no light, the points might be shorted to ground where the wires goes into the side of the distributor, or the condenser is shorted internally (test that by measuring
ohms from its lead (disconnected) to ground. It should show some conduction, then go to "open".
Going on from above 2 Put the test light on the movable side of the points (plastic in place). Good volts, or same reasonable light and we are near done.
Nothing and the points might be disconnected at the spring screw)
Last is to see if there is battery voltage from the movable points to the stationary points. If yes, the points need to be cleaned with 350 grit paper, then wiped
with a folded dollar bill (plastic out). It should run!!! Jim

Of all the things posted on here that is about as short and concise directions as I have seen. Very good directions. No Ohm meter or special tools.

Thank you. As time goes by teaching at a university, students are becoming less and less prepared to actually touch things or understand them. To take them into the real world of machine tools, and mechanical design takes a bridge of basic actions leaving out much of the assumptions about what they know. Fun stuff. Jim

Thanks, Jim
I understand every step of your procedure (didn't think my electronic VOM would work on the condenser)
Will try it today.

One of my failings as an old guy is not taking the time to "do it right".
You would think I would have learned by now..............

jc, while those ohm readings appear okay for a 6 volt coil THAT ALONE DOESNT TELL YOU IF THE COIL IS GOOD OR BAD. A coil may well show okay to a simple low voltage low energy ohm meter check and when cool and not operating at full temperature and higher voltages BUT STILL EXHIBIT HIGH VOLTAGE BREAKDOWN and fail to produce a spark. It requires an actual coil tester which most people don't own. A simple ohm meter can show if a coil is BAD (open or shorted windings) but cant tell if its fully GOOD............

Instead of guessing or throwing money or parts at a problem if you work through my Ignition Troubleshooting Procedure linked below it can help find the problem.

Today I started at the beginning ..........

Found an intermittent condition on the input power connection at the switch.

Thx for the good help.

Glad to be of help. John T procedure is also good. Thanks, Jim
