    Default Syncrowave 250- no spark at points

    Serial number- KG234930

    Can't get high freq spark- CR5 will not engage when remote is triggered.
    I have 2 remotes- both work with 2 identical Syncrowave 250's.

    Machine stick welds fine.

    2 Miller techs gave me my checklist methods-

    • Backfeed 115 volts (wall circuit) to low side of hi freq transformer.
    Worked! Beautiful blue sparks (clean, shiny- gapped.008)

    • switched PC1 board from identical, working machine- next serial number : )
    Working board didn't help CR5- suspect board controls donor machine.

    • switched CR5 from same machine-
    No joy- CR5 doesn't function in remote.

    • switched S3 switch-
    Same thing- nothing, nada- no hi freq sparks.

    What am I missing?

    Thanks, in advance.

    Mike
