    If AF1 fuse is open it means the large fuse underneath in the chassis for the power transistors is open. Do you have alarm display LED "4" on?. If so you may have shorted/open A50L-0001-0096 transistor(s) in power section.

    Correction. AF1 is for power supply on control PCB. Is PIL LED on? Check control voltages on PCB. +24VDC, +15VDC, -15VDC, +5VDC. Check pins on PCB for these. CT - 19A, 19B (VAC). May have a short in external wiring for Sensor (orientation)
