I have a 1985 Miller bluestar 2e AC-DC that I just bought it need the plunger solenoid and auto idle board I think. If anyone knows where to get one and or has one for sale let me know. I can't find anything for this welder.

Will need ser no to find the manual. If you have the manual already, look up the Miller part no, then check at Miller4less.com.Comment

Solenoid is available here.
idle board is here.
Will cost you a few hundred bucks but at least parts are still available. Hope you can get it fixed.

Weldmart I believe also has a idle board ,did you check the auto/idle switch first .Best thing to do is download a manual for your machine it helped me a lot to trouble shoot my machines .
There are a lot of knowledgeable people on this site I'm sure someone else will chime in soon. DComment

Here's the link to your manual if you don't already have one. Have you done troubleshooting that found both the board and the solenoid bad?

Did some troubleshooting today. The solenoid seems so be getting voltage and wants to work but I think it's getting too much voltage. The wires are getting hot and smoking....Comment

...or maybe there is a short in the solenoid? Seems most likely. The parts list says it is a 12v solenoid. Not sure how much current it should draw, but you might try disconnecting it from the circuit in the welder and applying 12 v from a battery using the same size wire as in the welder; see if it pulls in, or pushes out, whichever is correct, to see if it will move. Also, see if the wire gets hot. If it does, you have turns shorted in the solenoid. from the schematic it appears the solenoid has two wires, rather than making a ground connection through the case. If so, with it still disconnected from the welder, check resistance between each wire and the case; I assume it should be infinite (OL on most digital meters). If not, I would think you have a short between the coil and the case. This will at least tell if the problem is the solenoid or something fried on the board.Originally posted by Racer16j View PostComment

I'm gunna do some more investigating tonight. If I can't figure it out I'm gunna take the board out and give it to an electrician I work with to check it out and replace the bad.Comment

Any luck on the bluestar ???Comment

Had the board rebuilt by the electrician at work... Long story short I think the person that had it before has the wiring jacked up because it blew the board again... Think I'm gunna get another solenoid and just wire it 12v and just have a switch to manually put it into weld for now. Can't find a wiring schematic to where all the wires go on that board because I have two spots open that don't have a wire. But I have two that have two wires into one plug on the board.Comment

Wiring diagrahm shows the board pc1 and were the corresponding labeled wires go click on the link in the above replyComment

Update
Bought a new idle PC board and 12v solenoid got it welding. Just can't figure out why I turn it from idle off to on it runs high idle and won't drop back down. I need to adjust the rpms on it. But am stumped on why the auto idle won't work. All my wires seem to go to the right places just can't figure it out but at least it's welding now.Comment

Did you check the auto idle on/off switch ?Comment
