Default Coil OHM's Test??

Hello, can anyone tell me the procedure to check for a good/bad coil? The coil I have is the plug/connector style off a 07 Street Glide. It has 4 male end posts. I just need to know what posts I check with the OHM meter and what the resistance should be. Thanks for the help. I googled but only saw the older style coils that do not have the plug style connector.

I don`t know what those pins go to either, but the first thing you should do is check each pin`s resistance to ground (make sure you have a good ground connection). There may be only one pin that is ground (or is the same as ground), but if you read anything from any more pins your coil is toast anyway.

I found some info online about testing a similar plugged coil off s Subaru Forester. It had the 4 metal male end prongs are labeled A B C D. It said to put your multi meter leads on A B test the resistance and then on C D and test. I tried it this way and my meter reads OL on both tests.

This might be the completely wrong way to test it but it was the closet info I could find with that style plug.
