Not sure if im jumping at shadows but the power connection from my power supply is feeling very hot. To explain better, from my PS I have some heavy duty lanscaping cable (3.3mm) which is then soldered to a 2 core connector (female). From the controller I have the same heavy duty cable soldered to the 2 core male connector. The connectors are 18AWG according to the connector markings. it is the actual connector which is getting really hot. Should it be doing this?
