A stereo memory line might be another “bypassed” load[links]
The next step is to get the power from the house battery up to the switch panel where we can use it to do some good. Two conductors – a positive from the battery switch (with a fuse) and a negative from the ganged together battery negatives should be ran to where the central switch panel is. You should use marine grade primary wire for this. [links]
This is sometimes a long wiring run on a boat. Plus these two conductors will carry the current of all your electrical loads combined, so they are typically fairly beefy cables. Even a small boat (3-5 loads) we’d recommend at least 12AWG wire for this. 10AWG for larger boats (5-10 loads) is normal. 8AWG is getting toward over-kill in most cases for boats under 30ft. [links]
Batteries have positive and negative. For current to flow (which does the work) a complete circuit must be made from positive back to the negative. Any break in the circuit anywhere will stop the load from operating (which you probably already know or you wouldn’t be reading this to try and fix your marine wiring issue).
Both battery positives are running through this switch, and you can use it to select which battery you want to output, similar to an A-B switch. But a 1-2-BOTH marine battery switch also allows you to parallel both batteries. Both settings might be used when you are running your engine and want to charge both batteries from the alternator, or if you need to parallel the batteries in an emergency to help start your engine if your start battery becomes too depleted. more
With the B OAT H OW T O Wire Size Calculators, you can determine the proper size for the conductors on your boat based on ISO and ABYC standards.
. is the maximum amount of current that a conductor can carry safely without overheating and melting down it's insulation. The greater the diameter of the conductor, the more amps can flow through it without it reaching a critical temperature. But there are three other factors that come into play: more
If you are based in the United States, the ABYC Wire Size Calculator gives you the wire size you need according to the American Wire Gauge (AWG) system.
The calculator is based on the ABYC (American Boat and Yacht Council) E-11 standard.
Because it seems to be so many types of solder out there, choosing which solder to purchase can be confusing.
Solder based on lead was universally used in the past. It was made of a mixture of tin and lead. Usually a 60/40 (tin/lead) mix, that melts at around 180-190C degrees. more
When I started out in electronics I had no clue, so I just used whatever solder I could find. But did you know that solder is not only used for soldering electronics?
As you can see there are endless combinations of sonar and component configurations available. When in doubt look for a sonar representative or a store associate for advice.
Here all units would be connected via Ethernet and NMEA 2000. The Ethernet cable will be daisy chained between sonar units, weather module if installed, basically plug-n-play. NMEA 2000 would also connect to all the units that require NMEA 2000. NMEA 2000 is a bit more complicated and requires some additional components such as a power node, tees, cables and end cap resisters. See the attached photos of Ethernet and NMEA 2000 set-up.
There are many options in rigging electronics. Keep in mind if you plan on using 2 stand alone sonars such as the Lowrance Elite series on the bow with a transducer on the trolling motor and the other on the console with the transducer on the transom, you could run into cross talk if both units are used on deeper water. There are some ways to alleviate this by setting each unit to run on different frequencies or adjusting ping speed if they are capable of making these adjustments. Or going with units that are networkable, units like the Lowrance HDS series you can select which transducer to source to read. more
Hopefully this article helped you to make a decision on a sonar package that will fit your needs.
You can spend less than $100.00 for a quality stand alone sonar unit if that’s all their budget allows, and meets the criteria for your fishing style. Or the skies the limit with multiple networked sonars with StructureScan technology, stereo, auto pilot and more! more
Here is an overview of NMEA 2000 and Ethernet capabilities.
● NMEA 2000 shares data such GPS modules, engine data, limited waypoint management, Sonic Hub, autopilots control for a bowmount trolling motor or a main engine auto pilot and more. NMEA 2000 requires a separate power source to power this network.
● Ethernet shares data such as map cards, waypoint management, syncing multiple sonars, weather modules, screens and more… here
