Rotax 914 Electrical Diagram
Posted: Fri Jul 24, 2020 10:50 pm
I hope someone can help me to understand the Wiring Diagram on page 3, section 24-00-00 of the Rotax 914 August 01 2019 Installation manual. I am installing this engine without the external alternator. Here goes:
1.Where does the master switch (34) go in the diagram if there is no external alternator?
2.What does the symbol directly above the number 34 mean?
3.I am told that the 50A circuit breaker at position 43 should actually be a 25A circuit breaker if I am only using the Integrated Generator.
4.What is the purpose of the 5A circuit breaker at position 45?
5.I can see no fuse or other protection between the Battery Relay (38) and the Ammeter (37) which will be on the panel. The LAA technical leaflet on Electrical Systems advises that the battery positive terminal is a good place to have the big fuse (I assume that's the 80A circuit breaker at position 44 on the diagram) which protects the cable between the battery and busbar. Why does the Rotax diagram not show 44 and 37 the other way round?
6.Which of these fuses can be positioned forward of the firewall?
7.Does the relay at position 58 take the place of a panel mounted contact breaker switch controlling the alternator (or generator)?
8.What is the purpose of the 1A fuse at position 42?
9.Does anyone know if there is an explanation of the symbols used in the diagram available anywhere?
Thanks
