    Help with MFD Diagnosis

    I am in the process of diagnosing the problem with my MFD in my 96 SLX 780. I have read at least a 100 threads on the problems with these but have not seen any posts on my problem. I have removed the MFD and tested it and to my delight it does work when hooked up to power. So I changed the fuse in the electrical box which did look good but still no power to MFD. I hooked up a volt meter to the terminals of the fuse holder and am not getting power on either end. (I did of course hit the starter to wake it up before hand)
    Could I have a bad circuit board in the electrical box possibly?? I know the guy I got the ski from said he jumped it before and that is when the display stopped working so I figured he either fried the MFD or just blew the fuse. Unfortunately, it sounds like it may be something else. Any help or direction would be appreciated.

    The terminal board may be bad. Open the box and check for power on the red/purple terminal. could also be the fuse or the fuse holder.

    I will check that out tonight. I did check for power at the plug when I had the MFD out and did not have anything but I will check in the electrical box. I was wondering if it is common that the boards to burn out?

    They dont burn out, they are just terminal connections. But what can happen is corrosion from water getting into the box. Open it up and check it out, and clean everything as necessary.
