rx8 - strange behavior

[wallot]

Can anyone explain what really happened?

I got t8 motor from service and needed to test it along with my new CC1518. So I connected my good old RX8 to the T8 motor and everything worked, I disconnected battery, disconnected the motor and connected CC1518 and of course the battery and nothing. Not a single beep, no LED. HMM I tried my backup RX8 and no problems. So i tried to connect the original RX8 to hotwire and nothing. Hmm dead. How could this happen. I did not short any wires as I use EC5 connectors everywhere. Was already looking for a new ESC when I decided to try the RX8 again (4 hours later). And it worked. Connected it to the CC1518 and everything is ok. what is going on? Ghosts?
