In accordoAll right, but what I'm saying is that if LED a to the board only powered the LED you have to turn on after a small delay this should do it with this opto coupler, and clear that after I operate the tape the LED makes it flash the micro, tell me where I'm wrong.
Hello everyone, I have a problem with the pcb of the console of the Nordictrack Elite 4000, I burned the transistor BD438G I replaced it but after a while it burned me one of the two cooling fans, now disassembled, the replacement transistor I have, I ask, how do I have to weld it, I want to place the photos before and after, thank you all.In accordoAll right, but what I'm saying is that if LED a to the board only powered the LED you have to turn on after a small delay this should do it with this opto coupler, and clear that after I operate the tape the LED makes it flash the micro, tell me where I'm wrong.
I think the thing is simple for you and less for me, the problem is to be able to increase and decrease the speed of two 8 vdc fans, at the moment feed the board and as the output voltage increases or decreases it is always 12.22 vdc, I changed the transistor but in my opinion it is not connected right, The two small capacitors I tried are from 100 microfar to 16 volts and one of these does not give me the value ,other thing it can be.I have only worked on the main (motor) boards.
