Location: Hugo, MN | Make sure when you wire a unit with GPS that it can be switched off. There are two sets of 12V power inputs, one for the unit, one for the antenna. If you don't break power to the antenna while the unit is off, it will continue to draw. Next time you try to start your motor it'll be dead. Although there are interference issues with running power into the console, it's best to do so. Or you could add a switch up by the unit. I use shielded wire for my units and ground the shield, which helps drain any interference you might pick up along the way. Also, don't tie your power wires tight to the trolling motor wires, as this will many times cause interference from EMF, or electro magnetic field, which forms around higher voltage lines and lines with varying amperage such as your trolling motor.
Not sure if the units with an internal antenna need seperate power inputs since everything is internal, so if that's the case, don't worry about the switch so much. |
