It appears that the rotax 912 ULS charging system is an alternator (i.e. there are no permanent magnets, there is a "field" circuit on the rectifier and the field coils need a bit of battery power for the system to operate) but the manuals refer to the built in power system as a "generator". Is this just a translation item? If indeed I have an alternator, why do we not bother with the alternator field disconnect (wiring diagrams just show direct connection to the downstream side of the master solenoid? A more general question, all the circuit diagrams I have for the engine, my composite design panel and general use circuit diagrams do not show a fuse or breaker on the primary power supply to the main bus (power panel) from the At up to 50A, Im thinking that this circuit should be protected against short circuit - wouldn't a short cause a fire hazard? If a fuse or circuit breaker is a good idea, Im assuming that I would install as close as possible to the master solenoid - any advice re circuit breaker or fuse and location? Appreciate any words of wisdom. Thanx Vic Victor Menkal,P.Eng.
