I just bought this tractor and it was pretty rough when I got it. I got it home and took the hood off. I found most of the wiring disconnected and a gas tank rusted to hell. It did have an alternator on it so I assumed it was 12v already. I started looking on this forum to get some advice and knowledge of these tractors. I then ordered all of what I thought I would need to get her back up. After the initial tear down and clean up, I started installing the new parts. Points, condenser, cap, rotor, plugs, wires, cleaned and change everything in oil system, new carb and fuel tank, re-wired everything to a diagram I got from here, new ballast and ignition. I had an issue with points that came in kit so I went to napa and bought GOOD points and condenser. She fired right up. Oh, and installed new battery-almost forgot that. NOW, it won"t start unless my battery charger is hooked up to it-obviously not getting enough from the battery. I didn"t change the coil-assumed it was 12v, I have very little spark at the plugs-almost none-and that baffles me how it can start with almost NO spark-so little I can"t see it. Your thoughts, questions and advise will be appreciated.

id you use the 12250 (factory type) ballast & no other? Use Ohmmeter to measure coil primary resistance (top stud terminal to coiled spring contact on bottom). ~0.5 to~1.5 is 6v and ~2.5 is 12v. what do you have? Might try old condenser as well. Might also try jumper across ign sw as they seem to be a problem area.
 
ditto what jmor said.

ID what you have first.

next. clarify.

will it turn over good without the boost, but just not fire?
 
Measure your battery voltage at the battery with the engine at 1/2 throttle or better. Should see 14 volts on your volt meter. Hal
 
Yes, I used a ballast from YT. All electrical parts are new , except coil and alternator. I'm only getting about 13 from alternator-which is low. I'm trying to locate my brand new ohmmeter(dam kids)to get a reading at the coil.

Sorry, but "a ballast from YT", means nothing.
