Last few days have been spent installing the wiring, the Emergency backup switch and the Emergency Backup Battery. This morning I picked up a small 12 volt 5 AH battery for use as backup power. Work was completed and the plane placed outside and started again for a test of the Emergency Backup Power source. Switching onto the Emergency Battery and turning off the Main Alternator and Master switch kept the aircraft running fine. The backup battery supplies power to the Electronic CPI programmer and Coils alone. Numerous switching onto the backup at various RPM's was a success. I made a battery box for the new Aux. battery out of foam/fiberglass. It is mounted right behind the seat back in the luggage compartment and is secured to the floor. There is a Emergency Ignition switch mounted on the far left of the panel. Magnetos have been totally disconnected but not removed. Each battery can be tested via a volt gauge prior to starting the engine and charge voltage can be tested after the engine is running. The plane is all buttoned up and prepared for first flight on the SDS Electronic Ignition.
