I spoke with Dorn who did the second alternator field approval with the guy in the AOPA pilot that wears the helmet and nomex. He said it was pretty complex and very expensive as a new circuit needdd to be designed and there were some fittment issues with the back up alternator given the J's lack of working room behind the accessory panel. Also required a DER for the sign off on the 337. Not for the faint hearted.

I am entering the second week of upgrading my panel to three Aspens with external battery backup, replacing my Century IIB with an STEC 30, and replacing my vacuum driven attitude indicator with an RCA 2600 with external battery backup.  Since there will be no remaining vacuum driven instruments on my panel at the completion of this upgrade, the avionics shop wants to remove the vacuum system, including the vacuum pump.  My MSC, however, doesn’t think that this is allowed because my J left the factory with a vacuum system.  The MSC thinks that the vacuum system must remain even though it will not be serving any purpose.  The avionics shop believes that the vacuum system can be removed because the new panel makes it completely irrelevant.  Anyone have any thoughts on how to resolve this issue?  My preference is to give the avionics shop permission to remove the system, but I don’t want to do anything contrary to regulation.

Who ever this msc are..they are complete boobs
