Syncrophaser

[KyleTownsend]

Our Synchrophaser is out. It's been out a while, but it used to work.

When I put it in the "sync" position, the light just flashes but doesn't sync up, even when I have matched up the RPM's very carefully by hand.

As a test, I turned it on with the engines not running. The light stays on solid. I suppose that this tells you that the system is correctly detecting that the system is synched at that point (which it obviously would be), but I can't remember the exact point of this test.

Anyway, just wondering if anybody had any clues on what to check first.
