Help with Ford 600 spark

I have a Ford 600 that we are working on...it's in rough shape but I got it to jump last night with 12V at starter and the engine cranks so that is my first good news. Look like wiring is a nightmare. Most bolts are rusted and un-removable so will die grind most of them off to even get the sheet metal off.
Question 1) No spark while cranking, but will there be spark if a real dead battery? Not sure if generator will deliver spark if 6V battery so far shot. I want to check wiring as next step as maybe ignition switch is bad.
Question 2) No key switch on this one....; Isn't the left side under wheel ignition and right is lights? Both switches look rough but still no spark.

Question 3) Can I remove 6V battery and run 12V jump box at battery cables? I think the coil may get damaged so I'm a bit leary to doing that....

Question 4) I need to answer this myself but 6v vs 12V is on my mind. My old 960 had 6V and always started rough but thousands of 6V tractors out there. It sounds like I can but a 12V conversion kit and keep 6V coil. Is that the way to go??? I also like the idea of point removal with ignition system.

Found this from SOUNDGUY from a couple years ago....I think I'll try it. Thanks to him in advance!

for basic testing, a wire from the oem thumb starter switch to the solenoid trigger terminal, bat and starter hooked up.

wire from bat ot thru key to coil primary 1 side.. other side primary out to dizzy, coil secondary to dizzy cap.

that will MAKI it run

Dead battery equals NO spark. As for using a 12 volt battery to see if you have spark I do that all the time. Ya if you run it that way for hours it is hard on the coil and the points. If your really worried about it just put a ballast resister like the O'Reilly's auto VR-1 in the wire between the ignition switch and the coil

OK, so no spark from generator if the battery is dead....good to know. I kind of thought the generator would not be strong enough at crank without a good battery.

I can hook up a 12 V that I have right to the terminals (+ ground, of course).

thanks, Mike

Question 1) No spark while cranking, but will there be spark if a real dead battery? Not sure if generator will deliver spark if 6V battery so far shot. I want to check wiring as next step as maybe ignition switch is bad.

No, with a 6v system, everything must be right to get spark while cranking. The generator will supply power for spark only if it is spinning fast enough to generate enough power, as in pull starting it. If there is just a little charge in the battery, you can check for spark at the points. Just turn the ignition switch on, take the cap off, arc the points. You should get a spark at the points and the coil should fire each time the points break connection. If no spark, there may be a problem with the wiring or ignition switch. A test light or volt meter will make diagnosis easier.

Question 2) No key switch on this one....; Isn't the left side under wheel ignition and right is lights? Both switches look rough but still no spark.

Impossible to know which switch, just have to trace the wires, check the switches. Again, a test light or volt meter will be the best way to check the function of the switches.

Question 3) Can I remove 6V battery and run 12V jump box at battery cables? I think the coil may get damaged so I'm a bit leary to doing that....

You can jump it from a jump box or another vehicle, or put a 12v battery in. It won't hurt the coil unless it sits with the ignition on and the points closed. What you do have to be careful of is burning out the starter. You'll need to have everything ready, know that you have spark, fuel in the carb, everything set for a quick start. If it doesn't start in about 10-15 seconds of cranking, STOP! Let the starter cool while you look for the reason it didn't start.

Question 4) I need to answer this myself but 6v vs 12V is on my mind. My old 960 had 6V and always started rough but thousands of 6V tractors out there. It sounds like I can but a 12V conversion kit and keep 6V coil. Is that the way to go??? I also like the idea of point removal with ignition system.

The advantage to keeping it 6v is to protect the starter and keep it original. Some 6v starters handle 12v well, some don't. Running a 6v starter on 12v causes it to slam the drive gear into the flywheel gear much harder than it was designed to. Also have to be careful not to crank too long, it will over heat quickly. The coil decision is up to you, a resistor is cheaper than a coil. If your coil is good, just install a resistor. If you want to replace the coil, just get a 12v coil that doesn't need a resistor. Both will function the same. The electronic ignition conversions are great! But, you have to decide what system you will run. The conversion kits are voltage AND polarity sensitive. If you decide to go with 6v positive ground, you will have to be careful to keep it 6v positive ground, no reversing the polarity, no jumping it off a 12 volt.
