So I'm using the standard testing procedure on this dual output coil and I think the verdict is that the coil is bad. But because this is my first time testing a coil I'm doubting myself. Here are my readings. Can you let me know your thoughts? Images are titled according to test step.
- Using the lowest scale on the meter, measure the resistance between the primary terminals with the wires removed. Should read from 2.5 to 4.5 Ohms.
- Using the highest scale on the meter, measure between one of the primary terminals and the center core of the coil. Should be infinite resistance. (open)
- Measure between one of the primary terminals and one of the plug wire terminals. Should be infinite resistance. (open circuit)
- Measure between one of the plug wire terminals and the core of the coil. Should be infinite resistance (open circuit)
- Measure from one plug terminal to the other. Should be 15,000 to 20,000 Ohms
