2N with no spark

It was a cold night and I was trying to get my 2N started so I could push some snow. It was turning over slowly but I was getting a single ignition every so often. To get it to turn over faster I hooked up jumper cables to my pickup (bad move I think). The 6V was still hooked up to the tractor (another bad move). Someone slap me. After trying to start the tractor with this setup I wasn't getting ANY ignition. I pulled one of the plugs and found that I wasn't getting any spark. WHAT DID I DO? Any suggestions on steps to troubleshoot this would be appreciated. Someday I'll learn.....

If you replace the resistor, be SURE to replace it with the type that has the mounting block built on. It took me 10 years to finally figure out an intermittant loss of spark that I traced to a faulty mounting block. As I had replaced the resistor and had, as advised, checked the resistor itself for continuity a million times, I kept changing coils, wiring, plugs, points, condensers ad nausem. REPLACE THE MOUNTING BLOCK WHEN YOU REPLACE THE RESISTOR IF THAT'S YOUR PROBLEM.

You did not tell us where you hooked the battery from the pickup... If you jump 12 Volts (assuming your pickup is 12 volts) directly to the starter, it should not cause any problems. However, if you hooked it on your 6 volt battery, it could cause your problem. I would look at the points and if they look like they have not been fried look at the ballast resistor, it could have opened. Now that we have all the inexpensive parts out of the way, you could have turned your coil into a crispy critter.... The best way to tell is to replace it..
Good Luck
Happy Motoring

Not enought info. Did you hook the 12V to the 6V battery? If so, it could have taken our your battery (does it still turn the engine over?).
2, You could have fried the points and or the coil.
Send back exactly how you "jumped" it and what ground point you used as well as the pos contact point.

I hooked the 12v in the truck directly to the terminals on the 6v battery. I've already installed a new coil (I had one on hand). I'll check the points next. Why would it make a difference if I hooked up to the 6v rather than directly to the starter? I understand that I might damage the 6v but why would I burn up the coil/points? Also, the 6v stills turns the engine over (it's not ruined).

You are still putting 12 V to a 6V system. The 12 V can burn open your resistors , burn your poings and fry the coil.
Probably all of that didn't happen if say the resistor went first.
I would suggest you check your points and if the are still good, chect to see if you are getting a good blue spark at the plugs.
If not, then start checking from the battery forward through your wireing.Get a Ohm meter (voltage meter to some), and check what voltage you have going to the coil and what you are gettng out of the coil (to the points) This will vary depending if the points are open or closed. Closed will be around 6V and open should be around 3.5V. >>> I think that is correct<<<
Dell or someone will correct me if it isn't.
If you arn't getting the correct voltages, check the resistors in line and get back to us on what you have found.
HTH.
You can find electrical system check out info on this site daily. Good luck and let us know what happens both good and bad.
