 Posted: Mon Oct 05, 2009 8:19 am Post subject: SD-8 Installation Item |
 |
|
I installed my SD-8 and then questioned whether the output line from the
relay to the bus was in fact correct.
I ran the line from the relay to the Master Bus (satisfies the simple B
& C drawing).
The questions: 1. Given my All electric Z-13/8 installation (dual EE
ignition) + backup battery, is it wiser to run the supply lead to the
Essential Bus rather than the Master Bus? 2. If I do that will the SD-8
still get remaining charge to the batteries?
Assumptions: Under use of the backup alternator (for whatever reason),
the majority of the primary bus items would be turned off prior to
flipping the switch on the SD-8.
Thanks,
Glenn

The SD8 as the ONLY alternator goes to the main bus.
An SD8 as a backup alternator goes to the battery
and e-bus loads are limited to 8A max. This lets
you fly with unlimited endurance with the main bus
down and the battery contactor off.
Now you have 100% of energy stored in battery
available for approach to landing by turning the
battery master back on.
B&C's recipe for success is for different dish.
