Brief Description: Starter Relay warning light and Switch Gaurds.
I have two back up circuits in the event my VP-50 fails. A back-up power source for the Alternator field excitation and the fuel boost pump. With the red guards open and the toggle switch in the 'Backup' position these two items will be energized by my conventional 'Auxiliary Bus' instead of the VP-50. I finished up by clecoing the top forward skin in place for the last time!
