I have a master and slave mp10wqd. I noticed that the slave was flashing green, meaning it was in batter backup mode. I unplugged the two small wires, one that is for the battery and the other for the DC adapter and nothing happened. Since the Vortech was acting as if it wasn't getting power I figured maybe the small end of the DC adapter wasn't plugged in all the way. I then unplugged it again and my finger hit the end of it and gave me a shock enough to throw me back a little, yell out F... and have my wife ask if I'm ok. After that, I noticed the adapter from the slave that shocked me was hotter than the working Vortechs adapter. I unplugged it entirely from the AC outlet. What happened? What do I need to replace? A new DC adapter? My hand is still tingling, I'm not sure if its from the shock or just in my head.
