I know some people are saying that the Stab Trim Cutout switches near the quadrant, cut the circuit to the stabaliser... But is this just the signal circuitry, or all d.c. power to the Screwjack as well.
I thought the Screwjack contains a transistorised power supply circuit that produces an a.c. supply for the brushless motors, which are required to turn the screwjack nut..
