    Question 96 SL 780 - MFD Tech Info and CDI Testing Request

    I have a 96 SL 780 that I believe has 2 issues:
    1. My rpm are limited. I think the CDI box inside the electrical box is bad. I would like to see if someone in/near ohio would be willing to try the unit in a known working ski to confirm that the eletronic unit is bad.
    2. Iím on my 3rd MFD. Last one was purchased thru E-bay and had marginal clarity on the screen. After one day, it was dead. Does anyone have detailed information about the signals sent to the MFD? I would like to build a replacement using arduino components. I would be happy to post the plans and programs (without warranty) on the site once Iíve made a working unit.

    Lots of MFD technical info can be found via my signature links. Most of the electrical signals are fairly simple. The fuel and oil level sensors need a low voltage, low current power source and a sensor to read the current flow (fuel level sender is variable resistance).

    The tricky aspect would be speedometer. Factory MFD uses water/air pressure transducer supplied via thin tube from the speed pitot under the hull. You may find it easier to just use a small GPS unit.

    Where in Ohio are you?

    There are at least 2 of us in the NE area that might be willing to help with the testing of the CDI
