[TowerTalk] Problems with YAESU Rotor

[Scott Bullock]

Mark, I find it hard to believe, as we have sold these for 2 years and not experienced these problems.  Why don't you talk to Yaesu tech support and try and figure out what is causing these resistors to heat up and burn out? The traces on the board are obviously burning out due to excessive current from too big a sized resistor being installed.  But what is causing all this current? Something doesn't sound right. What are you turning with it?

Which resistors are burning out, i'll look at our service manuals on it and see what I can find out for you.
