Hello
I have a question about the 737NG Main Battery Charger.
From the information I have been able to obtain the main battery charger is normally in the "transformer rectifier" mode. The main battery charger goes to the "charge" mode when the battery voltage goes below 23v dc.
The battery charger cannot go into the "charge" mode during any of these conditions:
Fueling station door open
APU start
Standby power switch to the BAT position
Standby power switch to the AUTO position, battery switch ON, and DC BUS 1 and AC TRANSFER BUS 1 do not have power
Battery overheat.
So when any of the above conditions are true, is the battery charger in the in the "transformer rectifier" mode.
Thanks
David
