Around 92 hours into Apollo 7 I lost all control of right roll and yaw controls with both SCS and CMC control.

I made sure all Auto RCS switches are correct and the enable relays are engaged but I just can't seem to get any control in normal.
The only way I've managed to restore full control is by switching to direct.

Am I just missing something or have I triggered some special case bug? I've attached my scenario.

Looks like a few circuit breaker and switch settings are wrong:

-SCS Yaw MNA and MNB circuit breakers are not in (Panel 8 ).
-Signal Conditioner/Driver Bias Power - Power Supply 2 is in the off position, but should be connected to AC2 (panel 7).

Welp, finally know what that switch is for. It was the Sig Con/Drv Bias Pwr switch. Read that wrong from the checklist when I powered the SCS back up.
SCS Yaw A and B are one of my futile attemps to get that part of the SCS to reset or something.

I should read more of the Vol. 1 handbook.  Thanks again. Happy
