I also had a port to add battery power from an outside source. Previously if I went out 30 to 40 minutes and reduced power on a down wind leg and taxied a long way leaving the transponder, strobes, radio, and EFIS on the battery would not be up to par. I could watch the negative amp flow on the meter. The original Jabiru engine needed 300 rpm to generate enough spark to start . I also fixed that by adding an E-mag on the left side and an improved Hon da coil on the right side. Now it's up and running before you can take your finger off the start button. This coupled with the 40 amp alternator that charges while taxiing makes the airplane much more reliable.Just my humble opinion. bobby ________________________________ Message 2 _____________________________________ Time: 09:30:02 PM PST US From: don van santen Subject: Re: AeroElectric-List: Re: DPDT Toggle switch for BAT and 2 Alternators? Bob, The manufacture of Advanced Flight FFIS' recommends the IBBS system and provides inputs to their systems for tje IBBS. For me it mainly a brownout battery to keep the two EFIS alive during starting. The EFIS system is the only source of oil pressure measurements. The re-boot for the EFIS takes longer than the time I am willing to run the engine without knowing the oil pressure. I have the z12 system minus the battery buss and e bus. I noticed that the standby alternator is connected to the starter contactor via a fusible link that uses a #16 wire as the fuse.The feed to that link is a #10 wire. I thought that the normal design was to use a fuse link 4 sizes less than the feed. Is it ok to use #14 wire or is the #16 there to protect the alternator from putting out enough current to damage the alternator The B&C kit I bought included a 40 amp anl which also makes me wonder about the #16 fuse link. Thanks in advance for any explanation. On Mon, Aug 27, 2018 at 4:17 PM Robert L.
