On the back side of the connector where the wires enter, locate the red and green wires. Set your ohmmeter to test resistance (and the correct range if you need to), and touch one test lead to the terminal on the red wire, and the other test lead on the terminal on the green wire. Your ohmmeter should read between 13.7 and 20.5 Ohms, so if it reads 15 Ohms your stator ignition coil is OK, if it reads
