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?  My email is Leroy@leroyhall.com
