have a problem with my mamba max esc

[RUSTY XL-5]

I was driving around yesterday, doing nothing crazy (which was unusual ) and all of the sudden my rusty just stopped. Upon further investigation, I found that the two power wires coming from my external bec had lost some insulation and had barely touched. I was about to unplug my batt (3s lipo) when they completely touched each other....thats when the bec went "poof" in a cloud of smoke. After that, I knew the bec was toast so I unsoldered it and continued to drive with the mm's internal bec for another 1-2 hours. I wanted to drive again today so I tried turning the mm on but it will only do the first "ring", it won't arm at all. I can't re-calibrate (tired that already) and all I get is a flashing red light. I even checked all of my wires and nothing is frayed or has a loose connection.

Also, my temps were always in check and under "comfortable temp ranges".


Any Ideas?
