In preparing for a long cross country, I am try to determine totalelectrical power needs for my system (I dont have onboard chargingcapability).Many aircraft, including my Piet, have a White-Rodgers (P/N 70-11126-5)continuous duty DC contactor that is used as a master switch relay. Ithink they are common on Pipers and Cessnas.Does anyone know what the current draw is on the low amperage side? Thatis, how much current is drawn to energize the coil in order to close theheavy-amperage contacts? I guess I could hook up a meter across the masterswitch poles, flip the switch, and see what I amperage reads on the meter,right?Thanks,Jeff--Jeffrey H.
