Hi im having some issues with my old 1989 sealey mightymig 90, i have removed what i believe to be a thermisto that is across the rectifier and it is testing open circuit/infinite ohms. i have the instructions attached which shows what looks like the thermistor symbol in the circuit diagram but it only has the whole rectifier assembly listed in the parts. what i would like to know is what would be a suitable replacement as searching the numbers on the part doesnt come up with anything [GEU(B or 8 not sure) 68710] im guessing it would be a ntc thermistor to pass current across the rectifier as it heats up? but what resistance value should it have?
