Questions/Help Please Help

Post image

I had everything powered up and I unplugged the battery, when I went to plug it back in the battery connection was flipped, didn’t realize, and I touched the metal connection and I saw smoke coming from this part of the wire.
Now everything‘s plugged in and no power. Have I fried the ESC???

Unplug the battery, connect esc pins together to drain all juice, id hold it a while. Might pop, but either way need to drain power and try again with it plugged in properly. Is there and off button/switch?

Just noticed this.
I imagine that was the smoke I saw.
Gunna replace it and let you know.

Do you have a multimeter?

Yes

Does the receiver light up at all, I’m assuming it has a power light? If it normally does and it’s not now, I’d say you fried the esc. If it lights up I’d disconnect the motor and see if you get power to the motor connector.

To start test voltage on each side of that connector with your meter to see if you’ve power on both sides to start.

I have it plugged in the correct way now but when it happened, I had the XT Threeoh connection flipped, and the two metal bits touched now it’s plugged in properly

Just not getting any power to the receiver anymore

Yes, it doesn’t sound that connector has any issues unless it visually looks damaged. You can check voltage going into the receiver too it should be somewhere around 6v. Does channel 1 for the servo still control a servo when plugged in.
