Default 03 Ultra Classic with no spark

Alright, I need some help from some of you technical guys out there....I rode my ultra about 200 miles saturday with no problems at all , came home and parked in the garage......got up to go to work today and wouldnt start...after further investigation I found no spark.....pulled the ignition coil off and ohmed it out according to the repair manual and everything checks out ok.....the 12v wire going to the coil is hot with the switch on, but i dont get any reading on the other 3 wires in the electrical plug going to the coil....It appears to me that the ecm could be bad, but Im looking for any other options before replacing the high priced ecm.....any help would be appreciated....thanks

How did you test the spark to determine it didn't have spark?
