I still admire 727 Captain.   However, after purchasing Sim Physics X, the 727-200 has 0 (zero)  DC Volts.  All electrical switches are on.   It was suggested to turn electrical switches off. Reload the C172 with all electrical components turned off, and then saved as the default aircraft.  Still no DC Volted.  Next I uninstalled then reinstalled the CS 727-200 to no avail.  Still no DC Volted.

I'm using FSUIPC Version 4.70b

Extend battery life = 0 ( indefinitely)

No sucess testing  electric_always_available=1 or 0 (located aircraft.cfg file)

All of this occurred after installing Sim Physics X and it's version of SimConnect Client v10.0.61259.0....
Perhaps running two SimConnect Client at the same is a problem.

Any suggestions would be greatly appreciated!
