    97 sl780 mfd lr23 problems

    Hi all, sorry if im posting in wrong section, im new,i have just purchased a 97 sl780, the mfd was not working when i bought it, but got a good deal, so wasnt to worried,it needed a new battery, so fitted it, and it fired straight up, problem is, the bilge is running constantly at a slow speed with engine off, also trim works with engine off, which points to a lr23 problem, BUT, if i disconect the mfd, the bildge stops, and the trim only works if i hold down the bilge button, as it should, and ski stillstarts fine, i am new to jetskis, and im starting to pull my hair out! Lol, any ideas? Thanks!

    Disconnect the bilge pump and see what happens. I've been seeing issues with the bilges shorting out internally lately. It then backfeeds the voltage.
