Hi all, I have (A:ELECTRICAL BATTERY VOLTAGE, volts) 12 < monitoring the battery voltage, and throws up a warning. The engines are running and the generators are switched on by default I notice, so power should be getting through. I have tried electric_always_available = 0 andelectric_always_available = 1 If this is set to electric_always_available = 1, does it guarantee the battery voltage remains at its maximum value, as I am still getting the warning setting this to 1, or does it mean the aircraft systems continue to function even though the battery voltage has dropped? The electrical section is actually quite short. I have [electrical]max_battery_voltage = 24.0generator_alternator_voltage = 30.0max_generator_alternator_amps = 400.0 I've not come across this problem before, so am stumped. Please help. Nick

Nick, It's been a long time since dealing with the electrical system IIRC there are many variables that just do not work. Maybe try (A:ELECTRICAL BATTERY BUS VOLTAGE, volts) instead. Just a thought, Roman

What vaue does (A:ELECTRICAL BATTERY VOLTAGE, volts) actually return?

This combines the battery voltage with the generated voltsthe | is an "or" statement.vololiberista

<Value Minimum="0" Maximum="30">(A:ELECTRICAL BATTERY VOLTAGE,volts) abs (A:Electrical genalt3 bus voltage,volts) |</Value>
