Put your test light or voltmeter on the coil terminal connected to the distributor, ground the other lead.
Open the distributor and watch the points.
With the ignition on, points open, should have approximately 12v or a bright test light.
If no voltage, move the test lead to the ignition side of the coil. If no voltage, keep tracing back toward the ignition switch until you find the break.
If voltage on the ignition side, but not on the distributor side, the points, condenser, or wire is shorted to ground.
If voltage is present on the distributor side coil terminal, turn the engine until thepoints close. Voltage should drop to zero.
If voltage does not drop, the points did not make contact, the wire from the coil to the distributor is open, or the distributor housing is not grounded.
If the voltage did drop, but still no spark when the points open, repeat the voltage test back toward the ignition switch with the points closed (circuit under load). If there is a resistor ahead of the coil, points closed, should have about 6v or dim test light at the coil, 12v ahead of the resistor.
Be careful load testing, don't want to overheat the coil or points. Test quickly, if the coil gets uncomfortable to touch, give it a cool down break.

Last niht I dreamed about the day that I plowed the field of about 10 acres over on what Jimmy and Dandy called the Ledbetter field. I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
