If the light stay lit constant then the points are not closing or the electronic module is defective or the distributor ground is missing | |

| + | 2B -- If the light never comes on then either the points are never opening, the condenser is shorted or the electronic module is defective. If the light never lights, you can disconnect the wire(s) from the negative side of the coil and test again with just the key on. The light should light, if not the coil is open. | ||
If the light is flashing on the negative side, then the primary ignition is working, and you will need to test the secondary which basically consists of the coil, cap, rotor and plug wires. | If the light is flashing on the negative side, then the primary ignition is working, and you will need to test the secondary which basically consists of the coil, cap, rotor and plug wires. | ||
