Help, Bad Short Circuit

[kianhon]

Stock Belt-CP
I installed my BEC into the receiver with black wire facing down and caused a short circuit, it is soldered with my GWS ESC. Then I removed the BEC from it, gave me three beeping sounds when I plug in the Lipo, but gyro won't stop blinking, move sticks but no movement with my servos. I put in my old Dynam ESC (without external bec), no beeping at all and my gyro won't stop blinking too, and no respond with servo too.

I change new servos, new HH gyro and still the same condition. Whats happening? Burnt ESC?, Burnt Receiver?, Burnt Motor?


Am i right that I should solder BEC's red wire with ESC black wire to the male dean? & vice versa.

On the receiver, all servo and ESC's orange wire should at the top and brown wire should be at the bottom? and BEC's black wire should be at the top?

If I buy a new Esky receiver, the one exactly same with what I'm using, should I get a crystal too? or is fine to just get the same receiver?

I did pull out the ESC's red wire after I connect with the BEC.

Hikss hiksss, my heli already down for 3 weeks:oops:

NO, don't mix black and red wires. You can't change polarity at will :shock:

The red wire from the BEC goes into the red wire from the Deans. Black goes to black. The BEC connects to the receiver the same way as all the servo wires. White/orange is signal, red is +5V and black/brown is ground.

It does sound like the receiver may have had it - although I'm not quite sure what was causing your short circuit. Do you mean you already had the BEC soldered in with the red and black mixed?

Yes, my Bec's red wire was soldered with the ESC black wire to the Dean. I did the same way in the Finless Bob video. White/orange is signal, red is +5V and black/brown is ground, so white wire should be at the bottom and black should b at the top when connect to the receiver?

I just sold my last Esky receiver, so I can't check which way the servo wires are supposed to go... But it's supposed to be the same way as all the others. You really need to solder the red battery wire to the red and black to black - and forget about that particular Finless video. Just plug everything in the way it's supposed to go and leave out the red wire from the ESC to disable its built-in BEC. It's simple, it works, and it won't fry anything. As far as I know, polarity is not reversible on proper switch-mode BECs, so at best you will be left with no power to the receiver if you solder red to black.

So you mean most probably ,my receiver, servo, and gyro is not toasted?

The test with your Dynam ESC sounds like your receiver may be fried, but I think the gyro and servos are probably still OK. If you replace the receiver, you can use the crystal from the old one.

Ok thank you very much.
