    Depends on what the problem actually is. If the EMM has no power or is dead, then it won't talk to the diagnostic laptop computer.

    The EMM's internal diagnostics are not exhaustive. Some problems can not be detected properly by the EMM, which is why specific tests for each component are often needed.

    Also, visual inspection of things like the CPS may reveal metal debris, which indicates possible flywheel or stator damage.

    If you find EMM schematics for any Ficht EMM (even non-Polaris), I would love to see them.

    I suspect DFI Technolgies has schematics, but beyond that I wonder if even Polaris knows where they are now.

    You might fnd something from the OMC RAM Ficht outboards...
