    Issues such as these are often attributed to low or intermittent power supply ...

    *Have the battery load tested ...
    *Check all wiring for corrosion including the fuse and fuse holder ...
    *Test the unit with a power cord direct to the battery (bypassing all boat wiring) ...
    *Test the unit on someone else's boat ...
