I should have included a link to the previous thread because it answers many of your questions:

Many have told me that a static discharge can indeed cause the ECU to report a power failure, although not everyone agrees. I didn't notice any of the receivers blinking, but to be honest, I might have overlooked it. I don't mount the satellite receiver directly on top of the bypass cover; it's on a mount that's glued to the cover. I'm going back to that configuration because the engine seems to run equally well with or without the cover.

Thanks for your help, BTW!
