Can someone help me figure this out? I have a 2006 290 DA that the PO had half installed the radar (dome was up but wire wasnt run). This winter I asked the mechanic to run the wire to the MFD. It works like it should and no complaints. One day the radar wasnt working so I took the MFD (Raymarine C70) out and went to tighten the radar cable connection at the back and ZING! I got a good shock that I wish I hadnt! So...now what do I do? The interesting part is that it works still, but I am nervous about a few things (stray current, parasitic draw, etc). Thanks for the advice
