If you said “Hey, that green wire seems a little odd; it disappears behind the heat sink next to that screw then reappears again at the top,” you are correct.\u00a0 What really sucks is the green wire is the transmitter off connection to the remote control.\u00a0 So, when the PA board was secured to the heat sink, the wire was trapped between the board and the heat sink.\u00a0 Since the components were cold, they did not pinch through the insulation right away, no.\u00a0 Rather, after the transmitter ran for several hours at full power, it got hot enough to displace the wire insulation and cause a short.\u00a0 Doh!\u00a0 The transmitter is off and it won’t come back on!<\/p>\n\n\n\n

This is a picture of the wire after it was removed:<\/p>\n\n\n\n

Haste makes waste.\u00a0 Unfortunately, it was someone else’s haste that ruined my Saturday afternoon when I was supposed to be taking my son to little league practice.\u00a0 I am sure that some not-so-kind words will be exchanged very soon.<\/p>\n\n\n\n
