All auto pilot functions on 737 NG 900 are working OK but I cant engaged the A/T knob to the "ARM" position. It shows the green light for a tenth of a second and goes off. So then I dont have the speed auto function ON. When I try to put the A/T knob to the "ARM" position a warning light starts to flash: I believe it says: "A/T PVRST". Any help?Thanks, Jose Landajo.

They are located on the lower electrical panel. When they are on, the blue "Bus Off" lights will be extinguished.http://artietheairplane.com/737_panels/lower_elec.htmThat link is to just that section of the overhead. Click "Back to overhead panel" to see where it is in relation to everything else.
