It's time to "fess" up...

It's working!!!
You can NOT have 3 terminators on the bus, one of the MCP2551 shuts down!
(As it's supposed to do!)

I forgot about a diagnostic terminator I still had jumpered in the system.

I guess some extra current from the ICD helped it over the edge?

The one obvious change is the ground connection. Having the ICD connected,
you probably change that.
