You need to make sure your coil matches the output of your ignition system. If you read through the specs on coils, you will see a wide variance on input resistance and voltage. You could install a coil that requires more current than your ignition can handle, or have so much resistance that at the input voltage your ignition supplies that the output will be greatly reduced.
