Location: Hugo, MN | I get it at work. I do a lot of low voltage wiring for HVAC controls and automation. Ask an electrician if they can get you a few feet, most should have it. There is a bare aluminum wire in the bundle that is the shield, and it should be grounded on one end, not both, to the boat's body, assuming it's aluminum. The transducer wire shouldn't cause interference, and it's probably shielded wire itself. If it has a shield wire at the end, it should be used. The biggest culprit is the trolling motor wire because of the massive amount of power running through it. You can hear it in your AM radio a lot of times when you have your trolling motor on. The shielded wire can help, but doesn't always. Some of the dots could be from another transducer if you're running two, or your unit may need to be set up differently. My old GPS unit was terrible because it ran the same frequency as my front unit. Got a fancy new one on my console and all is good. |
