Have any of you ever lost the “A” side of EC2?  I went to start the R7A w/Renesis yesterday and it wouldn’t fire right off as before.  Switched to the “B” side and it fired right up.  EM2 rpm was alternating between the actual RPM and NOP displaying.  

Will of course have to begin troubleshooting this outage, but wondered if any had seen this before, and where the fault lied?  

thx.

Doug
