MAO/SASZE/M1 - Intermittent spectrometer operation and improper shutter operation

Power supply problems within the spectrometer box caused a variety of problems including 
intermittent spectrometer operation and improper shutter operation.  The failure of the 
shutter to operate properly yields all spectra as bad irrespective of whether spectra were 
reported.
