also instslled new plugs just to incase the other was bad.

First thing I would do is charge the battery.
Specially if it is still a 6V system.
You need enough power to both spin the starter and fire
the ignition. A weakened battery often just doesn't cut it.

It is 12 volt system I charged it up hooked up had 12 vots ontop of coil and 12 on pigtail on bottom on coil and points are opening and closing fine .could I have burnt my coil up?

"could I have burnt my coil up?"

It's possible if you left the key on with the battery cable hooked up.
Are there any obvious cracks or melting on the coil?
Are you using a 12V coil or 6V and what resistors are in the circuit?
Should have the original ballast resistor on the back of the dash
at a minimum.
You have 12V at the top of the coil, that would indicate points open.
Does it drop significantly with them closed? If not they are not
closing (electrically) or there is another open stopping current.

12v conversion ? with an alt?

why do you pull the bat cable after run?

what's the rest of this story?

Tractor has been converted to 12 volt system and the reason i pull the terminal is because my on and off switch was broke and stayed on all the time yes i have a ballace resistor behind dash changed that as well still no firing

yes 12 volts with an alt. i pull the battery terminal cause on and off switch is messed up.I got home today and reset the points and put bak together and started running good again

wow... get that switch replaced. that's crazy. what if you need to kill power in an emergency.

oh wait. let me go get my wrench!

bad....

Glad to hear you got it going again.
I'd put a new switch in it as soon as possible.
