Do you not have any lights shining on your EHC? It's been a while since I've had an EHC, but I think you should have at least one or two lit up. When the "run" button is pressed, it should light up one of the lights on the EHC if I'm not mistaken. Also, when the bike is running, another light should be on. I'll see if I can find the schematic.
The more people I meet, the more I love my dog
