but a good starting technic is always switch off the avionics master and alternator master only battery master on for start.
hf,
Yes, I use this technique for starting. I then watch the ammeter when turning on the alternator, to confirm that it starts charging the battery.
i suspect the only place in the manual where it mentions turning off the BAT side will be in emergency procedures for inflight fire somewhere
RJC,
No, it's just "Master OFF".
