I have an RRC3 that has never flown. It has fired a couple of ematches in testing, but that's all. If it's not in use, it's in its anti static bag put away safely, and I'm very observant of polarity whenever I connect anything to it. When I got it out today, the drogue continuity is not working. I opened mDACS software to confirm it, and sure enough, the drogue continuity said "NO" no matter what. The way the circuit is laid out on the RRC3, the positive pins of all the outputs are hot when it is on. I checked main and aux and they were both hot, but the drogue positive pin was not hot. It is just strange to me because the continuity was working when I put it away, but the next time I got it out, It wasn't working.
Does anybody know what could have happened? To me it seems like a mosfet has died, but I don't know how it could have died without a high current passing through it.
