Tested Coil is this measurement acceptable?

[Eckl]

I tested my coil following Pete's instructions. In step 5 (outlined below) I measured 25K ohms. Should be 15-20K. Is my coil good or bad? Not sure if there is a tolerance here or not.


Testing the coil:

1. 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.
2. 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)
3. Measure between one of the primary terminals and one of the plug wire terminals. Should be infinite resistance. (open circuit)
4. Measure between one of the plug wire terminals and the core of the coil. Should be infinite resistance (open circuit)
5. Measure from one plug terminal to the other. Should be 15,000 to 20,000 Ohms

Eckl,

Your reading is fine if you have resistor plug caps. The caps each have 5K Ohms, so that adds 10K to the coil resistance. I need to edit that check list.

High five Pete! Thanks a million!
