    You have 5vdc on green and red at the board? How old is the unit?

    100psi gives you 1.450 volts on the MBB.

    The guys having a hard time trouble shooting a pressure transducer.
    Realistically once you've located the terminals on the MBB it should take about 5 minutes to determine transducer or board failure.

    I wouldn't encourage him to replace the MBB although it may be the right thing to do.

    I know I'm just trying to help my stocks out a bit. Lol since its warranty and if it's a good part I'm sure they will charge him something for changing a good part.

    Did you check the pins and terminals on the plug? Have had issues on suction transducers where the condensation rots the pins and or terminals on the plug. I use grease for electric terminals in the plug after replacing the connector.

    didn't mean to encourage , i meant if you have the right voltage supply and the right corresponding feedback the board is done , assuming after all that the plug and pins at the board are all properly seated ...

    i had one doing this but both the discharge and suction read 500 psig

    and unless you want to load software order the board by serial number , then all you have to do is make the appropriate config changes .

    order a board without the SN and you'll get a blank board IE no software
