To update my first post.I fixed the issue with this car blowing F2 or F3 or both. I isolated it to the car station terminal strip P24 terminal. It would hold the fuses with the wires disconnect on P24. I traced P24 to the toggle switch at bottom of cop back to terminal strip as P24C. There were 6 wires on P24C. I unhooked all them and one at a time hooked them up until I blew the fuse. The last wire to check was it. I then had to trace that wire to the cartop and it was a wire going to the SELECTOR! Who would have thought that? After removing the selector board I followed the trace from the plug to a diode. Of course the diode tested ok soldered to the board, but to check it properely I unsoldered one side and it was shorted. New selector board, reentered all parameters and did hoistway learn and I was happy to have fixed it.
