Tom Baker Posted May 30, 2021 Report Share Posted May 30, 2021 Did you check the flap breaker? Quote Link to comment Share on other sites More sharing options...
procharger Posted May 31, 2021 Author Report Share Posted May 31, 2021 yes I going to take a meter tomorrow to see if I have voltage to the breaker then what should I check how many volts should be going to breaker and how many volts goes to the the flap motor, can I put 12 volts directly to the the motor. Where does the power come from to power the flaps or to the breaker? thanks Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted May 31, 2021 Report Share Posted May 31, 2021 This will make a difference depending on what model plane you have. LS or SW. Even later LS's have different connections. Take the panel out and then push and twist each wire if this is an SW. If all the wire have been twisted to assure good contact and there is power at the fuse then you most likely have a bad board. That said if someone has had their hands in the back of the center panel or the passenger panel they may have pulled a wire loose. Quote Link to comment Share on other sites More sharing options...

Tom Baker Posted May 31, 2021 Report Share Posted May 31, 2021 The three extra wires are for programming. For all the work I have done on CT's I really haven't had to do much flap work. I've replaced two relay boards, and that's pretty much it. Quote Link to comment Share on other sites More sharing options...
procharger Posted May 31, 2021 Author Report Share Posted May 31, 2021 How much are the boards and where best place to purchase? Quote Link to comment Share on other sites More sharing options...
Roger Lee Posted June 1, 2021 Report Share Posted June 1, 2021 FD is the place to buy and I think around $700 and some change. Quote Link to comment Share on other sites More sharing options...
Anticept Posted June 1, 2021 Report Share Posted June 1, 2021 Pull and reseat the microcontroller. The thing that looks like this: If that doesn't work, flip the board and take a close look for any cracked joints. You will also need to do the same for the relay board mounted on the firewall that is the other half of the flap control, those damn things like to crack joints too.
