By the looks of your picture, the taped wire is supposed to be to your electrical cord block. The burned wire is probably the wire which gives the motor power. From the rear of the dryer take the small cover off the back right to the side of where the cord goes in.4x4 There should be a 3 terminal block there for all electrical connections from the cord. I'll bet 1 is burned off. You may need a new cord & block,also some high temp connectors to splice the burned wires back on to the new block. Make sure to put on new connectors and cut the wires back until they are shiny to get a good connection. If you do't you will burn them off again.
