Miller Bluestar 2E AC/DC missing wire going to brushes

admin

Hey fellas I am new to this forum. I have the manual for this welder but the electrical diagram is in Chinese to me. I have a Miller Bluestar 2E AC/DC welder. I was checking the brushes to see if needed replacement. I found only 3 wires going to the brushes.  Is missing one wire, maybe someone can shed light on this. The welder has been performing fine. I traced the 3 wires. The brush on the left, one wire goes to ground the other goes to the Rheostat. The Brush on the right one wire goes to the Capacitor and the other wire is missing. I was wondering if the missing wire goes to the resistor since one connector does not have a wire. Any input will be appreciated.

Reply:I believe the resistor only requires the 2 wires as it controls battery charging. Maybe someone more knowledgeable will come along like duaneb55.Ol' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw

Reply:I assumed that since there are 2 tabs per brush, they both get used.

Reply:Actually, this is the correct diagram. Anyone?
