Any failures with MMM V2 and ext. BEC?

got my v2 back on sat. , got it installed and decided to use a ccbec to see how long it would last , bench tested and got about 10 sec. of running and my ccbec smoked , so i went inside and took off the ccbec and put the red wire back in the plug and bench tested it , went back outside and got like 15 sec. before it was acting like it was losing signal , and then nothing...............dont know what to say except i was hoping it would last as it will snow here in a month or so and i want to run


so when i get it back from repair i am not going to bother turning on the iron , i will hook it up and see how long it lasts


oh and a side note i did leave settings at default except i changed the lvc to 13.2v
