First we need the serial number of your welder so we can look up the right diagram.
Second try to figure out what fuse is blowing, F1 or F2 ect. You can get a diagram in the correct owners manual with the parts list. To get it go to millers web site and select owners manual. sense this is an older welder skip the first serial number box and select the model name link. now enter the serial number and select the welder model from the list.
Down load the manual. There should be a number and a letter after roughneck need the complete model name.
If you can't figure out the fuse number, take a picture of it. To show where it is located in the welder. We might be able to help you figure it out.
