Bob:
I'm just about ready to begin my wiring in my 9A and I have a couple of questions:
1) My load analysis is as follows: day VFR Cruise - Main Bus - 15.9 Edurance Bus - 8.65 Battery Bus - 1.0 for a total of 24.8 amps.....my question is : should I use the drawing for "HEAVY ENDURANCE BUS", since I'm going to draw over 7 amps and utilize the S704-1 relay and 10 amp fuse for the battery bus?
2) I do plan on using an Avionics Master switch - I do know your thoughts regarding not needing it, but ...... my questions is: the Z-drawings depict 16 awg (6-8" run) from Main Bus to Diode and 16 awg (6-8" run) from Diode to Endurance Bus - since I'm going to install the AMS on the instrument panel, the run from the Diode to the panel will be about 14-18"......what do you suggest for the size of wire and what is the max lenght it should be.
3) Can I install the LR-3 Regulator and Battery Bus on the engine side of the firewall....It seems to make sense for I wouldn't have to run un-fused wires thru the firewall...
4) Can I run 14 awg wire to the Battery Bus from the + terminal of the battery, instead of from the Master Battery Contactor? and
can I run 8 awg wire power supply to the Main Bus from the 60 amp current limiter?
Thanks
Henry
