Tomorrow morning my plan is to temporarily bypass the battery switch and separate the ground that the batteries share. Also going to run a new fused power wire from the cranking battery to the helix. Also going to pull the transducer cable and lay it on top of the deck since it is close to the wire harness to the outboard. The fuzziness still showed even after key power was killed to the motor so not really sure if this is just Overkill.
