He is a member and manufactures replacement EHC's for Big Dog bikes. If this link doesn't work look him up under members. You can send him a private message. He will be happy to help you out. I believe on his EHC one of the led's indicates power to the ignition when the key is turned on. If so ask him which one so you can verify.
As far as testing the Ign Module, I don't know of a way to test it other than installing it in a different bike to see what happens. Someone else on this site may know of a way. You could ask Curtis. The manual for an 07 k9 says the best way to troubleshoot the module is by eliminating other causes until it's the only thing left.
Unplug the EHC and the ignition module and read continuity between the red wire on the IM and pin#14 of the EHC then read the black wire on the IM to pin 37 of the EHC. Disconnect your neg side of the battery so you don't inadvertently short something out while you playing with the wires.
CORRECTION !!!! When I looked at the wire diagram the pins were different than I read on the sheet. The black wire is the ground for the IM and is pin #37 but the power from the EHC is on pin #14.
