"Im assuming your talking about external ground power App.
Take switch from Maint to Norm and do pinch-pull FLCS reset ... CADC light will go out
Don't run external power without cooling air in Norm
T.O.s are online now ... get a CAC card reader, set up at home, and read them at home to enhance your knowledge! |

your assuming is right ,
and we did what you said and light still on
we apply ext, pwr without cooling.....
cadc , rdr alt , eca , aoa both , total temp prob, fwd avionicxmatrix #2 , flcc, flicht control control panel , vvi , aoa ind , are replaced light stay on
wiring check performed between all wires no negative results found
that make us crazy |

as i said in previous post we replaced all concerm=ning lrus no positive respnse ,, T,o has no further maint
and i would like to say the caution light came after 8- 10 sec since the main power to on
we track the power schematich duagram and we test the concerning relays the relay and the base and also we replaced them but light stay on  |
