  • Syncrowave 250 question

    I have a early 250 that somebody lost the amp. shunt. I talked to Miller tech and it's no longer available . He did say it is a piece of .094x 1 3/4 stainless but did not have any more dimensions. Anybody have any information and or Pics? The later used the Hall effect type which is also discontinued . Thanks

    What is the shunt part number..??? is it 114723 ???

      The Miller tech said the piece is 8' yes feet. The shunt is made with a small piece of it.

          Nothing is available, so my only option is to make a new shunt. From there I can find out if the CB is good or have it repaired. If I could get the dimensions and hole layout I could fab a new one.

              I asked Andy Weyenberg


              The hall conversion is a kit that includes a new main PCB because of calibration, Filter module, new hall device and some wires. It’s nothing they can modify with their current PCB.
              The best bet might be to try the 100mv shunt and see if that works.
              I tried to find the old voltage drop readings for the shunt but all I can find is the hall device readings.
              Try the shunt. Worse thing is that the PCB calibration is off and the amps out won’t match the amps set on the front dial.

              I’ll keep looking for info.

              A-

                Maybe someone has one from a conversion?

                  Where can I find the conversion kit? Really don't want to spend that much but might have to. Still hoping to find a shunt.

                          That is the part number I have. Do you think a 100mv 300amp aftermarket might work.
