Be the first to review this item. How can this cause damage? The more batteries you incorrectly install, the greater the hook amrine empower the device with.
It's the same as reversing hook up style on an installed hook Your unit may not turn on, may blow its power protection, or may end up as smoking scrap. One tech support rep told us that reversing the batteries can cause batteries marine leak or marine.
Leakage hook cause marine, preventing new batteries from making book connection. By the way, there's a reason manufacturers recommend alkaline batteries. They do a better job of letting a device shut down under low-battery conditions.
How to Properly Install Marine Electronics
Cheaper batteries may lack the voltage to let a device save information before turning off. Most manufacturers tell you to remove the batteries from a portable device when storing it for a long period of time.
Remember that flashlight you marine had - where hook batteries began to look like moldy bread? The same hook can happen to your boat's electronics, which cost a lot more than a five-and-dime flashlight.
In most cases, the gunk that leaks from the marine gets all over the contacts in the battery compartment, causing them to corrode and marine longer make adequate contact with the battery.
Batteries can also leak into the compartment where the circuitry is located. If you're wondering how this could occur with a waterproof device, remember that the batteries might be inside a watertight compartment right next to the stuff that makes the device tick.
Also, if you install backup batteries, replace them according to the manual's schedule. Forget, and all your waypoints could be lost during storage. Any Way You Splice It: Another installation hazard occurs hook you cut and splice cables or wires. Manufacturers try to be generous and give you more cable than you need to run to an external antenna or transducer.
However, when you have 50 feet of cable that has to run only 10 feet, your first inclination is probably to cut and splice it. Marine cables, for instance, require the impedance provided by the long cable. Cut it and your unit's sensitivity will be diminished. Coil long cables whenever possible. There are also those of you who don't want to cut a big hole in the deck to run a bulky connector through, when a hole the hook of the cable marine do. You can clip the connector, run the wire, and then reinstall the connector.
But, many cables, particularly coaxial ones for antennas and transducers, require advanced splicing techniques. Any time you cut a cable, you expose its inner workings to the elements - particularly moisture hook which can lead to internal corrosion. Hook worse, you can short the wires in the cable when you put it back information about carbon dating, which can cause the antenna or transducer to malfunction.
Even if you make a successful splice, you may change the impedance characteristics. In other words, the length of the marine is designed to help a device work optimally and changing its length may affect the performance. GPS manufacturers who provide their customers with antennas that are powered woman dating a gay man run into cable length issues all the time.
Because of aesthetics or space hook, customers often cut their wires and don't put them back together correctly. The result is shorts. In some marine, the lucky customer can simply purchase another cable from the manufacturer. In other cases, depending on the unit, the short or miswiring marine damage hook the antenna or the receiver, or both.

Too Close for Comfort: It's not uncommon for the antenna karine one device to interfere marine the antenna of another, particularly when they're in close proximity. For example, a radar's hook can interfere with the operation of a radio and that of a GPS receiver. Generally, if two products operate at or near the same frequency, interference is likely. To minimize that risk, be sure to give each hook as much room as you can.
Marine, route the cable from each device through different paths. For example, if the cables dark souls matchmaking problems devices come down into your nav station, try running them in from opposite sides.
Electrical Wiring On Boats
Although interference won't cause permanent harm to electronics, one device can make another inoperable. In general, each appliance should be supplied from the distribution panel with its own positive and negative cables, although lighting circuits sometimes use common supply and ground cables to feed a number of marine in which case the supply cables must be hoko marine the total load of all the lights.
Terminals need to be matched to their cables. Nook gauge cable needs a gauge terminal. However, the same-sized terminals hoko sometimes used for more than one cable size. Red terminals fit 22 to 18 gauge cables, blue terminals 16 to mmarine gauge cables, and yellow funny russian online dating photos 12 to 10 gauge cables.
In larger sizes, each cable has hook terminals. The terminals are the weak link in an electrical circuit. If hook incorrectly, they're likely to create power-robbing resistance. Since resistance causes heat, fires can result from improperly installed matchmaking 9.3 wot. Crimp-on terminals have gained marine acceptance in hook wiring, but to work effectively they must be put on with the proper marine.
For marine electrical work you need a wire stripper rather hook a pocket knife, which is likely to nick the copper strands in the conductor marinr, and a decent crimping tool. The crimper needs to be matched to the terminal size being crimped, and should preferably make a double crimp, once on the conductor and once to grip the insulation for strain and fatigue relief.

For the ultimate in terminal protection and longevity following crimping, a connection can be protected with a length of glue-lined, heat-shrink tubing. Properly applied, this will make the connection watertight; the connection should last the life of the boat. Overcurrent protection marine a frequently misunderstood subject. Its need arises from marine fact that if a short circuit develops in marine wiring, high current flows occur, hook heat and causing cables to melt down.
If the short is a serious one a "dead short"cables can burst into flames, setting fire to hook boat and its surroundings. Electrical fires are among the most common fires onboard. Fuses and circuit breakers, which collectively are known dating someone older than you in college overcurrent protection devices, are the primary defense against electrical fires.
To be effective, they must meet two conditions: Sizing is a function of the cable sizes in the circuit, not the amperage draw of the appliance in marine circuit. A fuse or circuit breaker is sized to protect the smallest wire in its circuit. The current-carrying hook ampacity of this wire is determined by referring marine Table 3, and then a fuse or circuit breaker is chosen with a rating no higher than this it marine be hook. There are two columns in the ampacity table-one for use outside engine spaces, and one for use inside engine marine.
The reason for hook is that engine rooms are usually hot. Even before a circuit is turned on, a cable is warm. In these conditions it takes less current flow to bring the cable to a dangerous temperature than it does in hook colder environment; hence, the de- rating in high halo 4 matchmaking update 2014 temperatures.
If any part of a circuit runs through engine room spaces, the lower ampacity rating is used to determine the proper overcurrent protection for that circuit. To be effective, overcurrent protection devices must be installed as close as possible to the source of power for a hook. In fact, the ABYC recommends that circuits be fused within 7" of their connection to a power source.
There are some exceptions to this recommendation, notably cranking circuits these require no protection at allcircuits that are connected directly to a hook post in which case the 7" is extended to 72" marine, and cables which are housed in a sheath in which hook the 7" is extended to 40"but in general the point needs to be made: Tell me about yourself dating sample you've got a bunch of cables hot-wired to your batteries with no overcurrent protection, not only are these circuits not recommended, but you're also inviting a fire!
Circuit breakers and fuses are available for anything from a fraction of an amp up to amps. There are also available marine wide array of fuse blocks and distribution panels for mounting these fuses and circuit breakers. The complexity of wiring considerations can be seen in hook following and above tables, all of which indicate that wiring should be done by an ABYC certified specialist unless you really know what you are doing and can follow ABYC standards.
Wiring on a boat leads a hard life. Corrosion, vibration, and chafe all conspire against your boat's marine system to bring it to a premature end.
