    If someone can post good quality photos of the connector, i will take a look at sourcing them and creating a MSX variant.

    To test the paddle wheel you connect an ohm meter to the 2 leads coming from the paddle wheel sensor. It will then cycle between resistance and OL if the sensor is working correctly.

    Here is a pic of the connector on my 2003 MSX 140. On my Matrix project, it came with a Deutsch connector, but I don't know if that was stock, or was modified by the person who had the boat previous to me. I personally have no problem with changing the connector on the paddle wheel sensor to be compatible with the GPS unit. Or if the original connector is hard to source, possibly supple the mating connector that we could then replace the paddle wheel sensor connector with as a kit.

    That connector is stock. Any ###,s on it?

    That is a somewhat standard Sumitomo connector. Not too easy to source in the US as it is a Japanese connector, but I can get them.

    You mention the test procedure, can you post the full text of the test procedure?

    All the manual text says is:

    1. Insert probes into the sensor connector with meter set to ohms.

    2. Spin the paddle wheel. Meter readings should rapidly cycle between resistance and OL.

    OK, can you use a meter and measure the resistance it shows when in the " low resistance" part of the paddle wheel travel?

    My meter must not be very good since all I get is a high mega ohm reading with no fluctuation. It does work on the gauge when I spin the wheel though. One pin of the plug is ground if that helps at all.

    Bryan can you measure the voltage pulse?

    Where does that come from?
