66NOTE: Many boats will have “upgraded” alternator systems in order to more quicklycharge the larger banks of batteries used on cruising boats. These systems will havetheir own unique wiring diagrams.d. Electrical StarterThe engine starter motor is the most demanding load that will be placed on theelectrical system and is not fused or protected by an overload device. Therefore, it iswise to make periodic checks on the connections at the starter and solenoid switch fortightness and cleanliness. Do not allow tools or other metal objects to come intocontact with these connections while the battery is on.e. Wire RunsWiring in your yacht is generally carried through wiring conduits. These conduitsprotect the wires from wear or impact. The color code used is shown in Table V-1.Where wiring is exposed, it should be checked to see that it is clear of potential harm.Terminal blocks and other exposed wire termination points should be sprayed withWD-40 or similar moisture eliminating product. It is very important to note that youshould never, repeat never, disconnect wiring or plumbing for that matter withoutdrawing your own schematic of how they were installed first. Also, make sure eachline is tagged using waterproof labels. Trying to reconnect later will be your worstnightmare come true, if you do not! It is very convenient to keep a “smart book” withall these schematics, part numbers, phone numbers, addresses, etc. This book willbecome increasingly important over the years! For example, when you replace theanchor light bulb, write down the type in your smart book, so you don’t have to go upagain later just to see what type you have to buy.2. The 110 Volt AC SystemThe 110 volt AC electrical system is connected to the shore power system. Its functions areprimarily water, heat, battery charge, power outlets, and sometimes refrigeration and airconditioning. The service capacity is thirty amperes and the system is protected to that level.There is little maintenance that the average owner should do. Whenever working on the back ofthe panel, it is wise to shut down 110 power. Remember, a yacht is a damp environment, andthis tends to increase the dangers of electric power. The 110 volt system is grounded in the yachtand this ground should remain. Remember – AC circuits and electricity can be lethal!3. Protective SystemsYour yacht is bonded to help prevent galvanic corrosion. All metal parts of the yacht thatmight come in contact with salt water are bonded by electrical wires with green insulation inorder to provide a low resistance electrical path for stray currents. Thus, there is a reducedlikelihood of current running through the salt water “electrolyte” and destroying the metal parts.The bonding system should be checked to make sure that all of the connections are good andclean. Incidentally, it appears that this bonding also helps keep your boat a less inviting targetfor lightning when sitting in the water. A typical electrical bonding system is shown in Figure V- 1. |
