Itâ€™s great to have access to your thoughts. With your recommended actions below following a main alt failure, does this mean you recommend operating with the Aux Alt always turned on ? Or is this turned on in addition to selecting DC PWR Off and E-Bus Alt feed.
Pre Engine Start:
E-BUS Alt Feed . . CLOSE for ATIS/Clearance
then . . OPEN
Normal ops: DC PWR master . . . BAT + ALT
AUX alternator . . OFF
E-BUS Alt Feed . . OPEN
On presentation of LV warning:
DC PWR master . . . OFF until airport in sight
AUX alternator . . ON
E-BUS Alt Feed . . CLOSED
E-Bus Loads . . . . reduce as needed
Airport in sight:
DC PWR master . . . BAT only
|Out of interest what is the SD-8 output doing when the Aux Alt relay is open ? Does it produce a steady 12 , or float around if I was measuring it ? |
14.0 plus or minus . . . it's not loaded
so the regulator is a bit sloppy until the
relay is closed to hook it to the battery.
