$700 for a bulb that didn't fix the problem of no console light.
The inverter is located outboard of the Captain's left rudder peddle (right peddle for F/O's). And yes........ the seat has gota come out.
Two power pins on A and C, which read 28VDC.
D and E are for the control potentiometer. 48.1K ohms full CCW, 1.2 ohms full CW.
