I am not sure which wires you are describing. Sounds like your two loose wires should connect to the "bridge rectifier", maybe it overheated and the two wires that appeared to be bolted down are actually connected to melted spade lugs. That's what happened to my GB5000, which may be very similar to your model. Colors of the wires and/or a picture would help if possible.
