    (SOLVED)820-00431-a 1led green no power no fan spin

    I don't have another 2015 board, can we go another way? I've seen no voltage at any time in L7110/30/50 Is it true that the coil resistance is normal 01.0 and they seem to be good So I don't understand why there is continuity to ground On L7100 I have voltage 1.9v increasing very slowly
