Heating Coil Melting Connector Insulation

Hi Everyone -- I'm putting together a little 250g FB for a buddy of mine. He's been hitting me up for a lb every other week and so I want to hook him up with a roaster and get him going on his own. I've got everything put together and working except I'm running into a heating element issue. I've got about 1/2 of a dryer heating coil that is wrapped inside an enclosure. Each end of the element coil exits the enclosure terminating in an insulated bullet connector. I then have a run of 12AWG wire running from my switch to the coil from the power source. When I fire up the element (fan running of course) the coil heats up and then immediately begins to melt the heat shrink insulation affixed to the bullet connectors.

I'm not sure what to do to rectify the smoldering plastic and give it a test roast. Should I just run it until it melts through whatever it's gonna melt? Or should I attempt to remove the insulation and give it a go?

Cheers!ThumbsUp

Personally I would get that insulation off the connector not let it burn off

Yeah, I went ahead and swapped the connectors. Worked like a charm. Thanks!
