electrical loads
Turn all switches off including avionics switches. The loads are measured by turning one switch on at time and recording the battery discharge current with that switch on. Be sure the cowling is still attached so the taxi and landing light loads can be measured.
Turn master switch on - record initial voltage and current after turn coordinator has reached top speed. All current readings are negative.
