See if your board is a 212708. If so, we can probably repair it. Miller list is 429.87. weldersales

Does anyone have a schematic diagram for the Miller trailblazer 301D PCB 212708? Parts available? Could I talk to some one about how it works? The main and exciter field have DC resistances of approximately 3 ohm and 30 ohms. Is this OK? How about the coil that feeds the bridge rectifier, what should it's resistance be?
