Well, one of the wires should have a voltage at all times. I thought it was yellow. In any case, it is probably one of the wires that are the only one of its color. If not, then you have more troubleshooting to do. The normal order would be to go from the diode bridge forwards, but it could be that the PWM (the TOP226) failed as discussed previously, as it's one of the most sensitive parts in there, and there was an overvolt condition.
