So this happened...
ESC stopped working. Internal voltmeter frozen at 28.7v. Tested dump batteries and they are fine. Connection between the two is OK (Running 3 PC680's).
Controller fan and aux unit fans go on, however the beeps weren't audible on startup.
So I looked at the connections from the controller to the turbine noticed the black and blue wires were singed and fused at the connection point. The electrical tape was melted. Managed to get them apart and they are blackened... See pics. The red connector is ok.
Anyone seen this before? Any idea of what could have caused this? What's the remedy?
Thanks.
