Can't be sure it wasn't the voltage drop that caused mine to keep blowing or something in the loom. That's why I didn't have the lights on yesterday just in case. Could also have been coils like you said. I can say that the Dmr loom is plug and play so that might help someone in the future. I want to get a few more miles on mine before I'm convinced its ok. I hope you get yours sorted zeus, keep us posted.
