Let me get this straight. If I am standing at the

FRONT of the 8N looking at the ballast, you are

saying, run a wire from the top of the coil to the

LEFT post of the ballast. On that same LEFT post,

run a wire to GROUND.

No, that isn't what he said. To re-work your statement, he said,

"If I am standing at the

FRONT of the 8N looking at the ballast, you are

saying, run a wire from the top of the coil to the

LEFT post of the ballast. On the RIGHT post,

run a wire to GROUND".

NOW, let me add MORE. At this point, you have not even established that the EI/coil/spark is your problem, sooooo, the FIRST order of business is to determine whether of not you have a spark at that moment when the tractor won't start. Pull a plug wire, hold it near grounded metal parts & look to see if a quality spark is present or not. Go from there.

IF you do determine that under 'no start' conditions that you do not have a spark, I suggest that you measure the coil primary resistance. Coils vary (maybe 0.5 to 2.5 Ohms) and Pertronix recommends that combined coil + any ballast resistance add up to a total of 1.5 Ohms for your 6v system. That may mean that a resistor is needed and it may mean that no resistor is depends on that primary resistance number.
