 |
|
Greetings;
I'm applying the wisdom gleaned from The Aeroelectric Connection and request feedback.
The Aircraft:
-A basic VFR Bearhawk Patrol, which is a Aviat Husky/Super cub type of aircraft
-Dual Surefly Electronic Ignition modules to replace Magnetos.
Electrical system Goal:
-Simple reliability,
-Power Dual Electronic Ignition, plus simple stuff like a comm radio, transponder, a fuel pump, LED NAV lights and a few other things.
The Z11 digram titled “Generic Light Aircraft Electrical System” is my favorite.
But the Dual Electronic Ignition needs are special. I called Surefly and they agreed that prudence demands I install a dedicated battery for each ignition module.
Further guidance from the Ignition Supplier
-Use a hefty diode to the Aux Batt to reliably protect it from back feeding
-Monitor the Voltage to the Aux Batt.
-Size of Aux Battery can be small, just so its duration exceeds the fuel duration. 8 amp hour?
Some here might be interested in electrical needs of a single ignition module.
-Required Voltage = 8-30V
-Amp draw = 0.7A +/- 0.2A at 2700 RPM
-Permanently connect Power to the + Batt terminal OR the Master Solenoid battery + input.
-Use 14AWG and a 10A fuse or CB.
-When the Ignition is placed in Standby mode (turned off) by grounding the P-lead, it draws less than 1ma.
So, I'm proposing a Z11 system with one ignition wired directly to a normal size Main Battery, and the second ignition wired directly to a small single purpose Aux Battery.
Although Bob’s Book has a Dual Batt diagram, In the spirit of simplicity I didn't use a solenoid for the Aux Battery, I protect the aux battery with a diode, and I will monitor the voltage of the Aux battery.
What are your thoughts?

Move the E-Bus switch so that it is between the battery and E-Bus like Bob
designed it. Better yet, have the switch control a relay so that power can be
shut off close to the source (battery).
