Can a bad connection cause heat?

[Jeremy1976]

This is referring to my MM ESC. I put a call into CC and left a voicemail to get back to me. However I started to recheck my work again and I noticed the male TRX connector I put on my ESC, the prongs are not all the way in like the Y series adapter I got. I can pull the leads right out. I tried pushing them in (supposedly they snap/lock into place) but no matter what I do I cannot get them to go in all the way. It still powers everything just wondering if this could be the culprit to my hot ESC. Also anyone have a good suggestion on how to get them to lock in place? I am up to the line or maybe just a tad over on the metal lead like I am suppose to be. Thanks
