Cables Connectors, and Plugs

Originally published in Atomic: Maximum Power Computing Last modified Dec You know what an uninterruptible power supply looks like, right? It’s a heavy beige box with an IEC power socket on one end, one or more three-pin sockets on the other, a few lights and buttons. Well, it can be. Or it can look like this. This contraption works in basically the same way as a normal “dual conversion” UPS. Next to the computer, there’s a big fat DC power supply, with a battery sitting on top of it.

My Olds has all the good stuff including a full roller valve train, billet mains, forged pistons, h-beam rods, Edelbrock heads, MSD ignition and a custom stainless exhaust.

I’m expecting it to make about hp and a pile of torque. Here’s where I would appreciated your input.

Drive System Alignment by David Pascoe The next time you have a vibration problem, before you automatically go sending the props off to the prop shop, or call for an engine alignment, check out the entire system so you don’t end up fixing what doesn’t need to be fixed.

Engine Cooling Systems Explained Our last contest consisted of selecting the order of things to check to troubleshoot an overheating engine with a “raw water” cooling system. A few of our viewers asked me to explain just what a raw water system was and how it worked. Raw water refers to the water that the boat is floating in. It makes no difference whether it is salt or fresh, both are used to cool the engine.

The process starts by drawing water into the engine through a seacock fitting and pumping it through the engine’s water jacket and ports by way of a mechanical water pump. In a raw water system the water is drawn up through the seacock by the water pump. The water flows through the engine and directly out the exhaust. This cooler water absorbs heat from the engine to help keep it cool. Most newer marine engines use an enclosed cooling system. This means that there is a small tank on the top of the engine that uses a combination of fresh water and coolant.

This fresh water is circulated through the engine and through a heat exchanger. The fresh water, in this system, absorbs the heat of the engine.

Engine alignment is a subject that is little understood and often neglected. Most boat owners aren’t even aware that engine alignment is one of those things that requires occasional maintenance, and is one of the last things to be considered when some kind of drive system problem develops. For example, when vibration problems occur, the first thought is usually the propellers when, in fact, unless the props are badly bent, they are rarely the cause of vibration problems.

More often than not, the source of the problem lies elsewhere. The subject of alignment is really not very complicated, but it does involve several other factors which most people are not aware of. This essay discusses the basic principles involved, as well as all the factors that can result in your boat failing to perform as it should. Anyone can understand it, and by taking the time to study the issue, you will not only know what to look for, but can save yourself a lot of money by heading off problems before they develop.

Important Guidelines Regarding Safety And General Construction Layout As I presume you have read the safety article Relating to the Crystal Set, The rules are exactly the same regarding the safe use of Antennas and the polarity of certain components such as the electrolytic capacitors and Batteries if you have built the amplified crystal set. The 2N FET is not as static sensitive as other expensive MOSFET devices used in other applications such as high power PA Amplifiers, But you must try to handle it as little as possible and try not to apply no more then 5 seconds of heat when soldering into the circuit which should be just enough to make a nice clean shiny joint.

Veroboard is suitable for the audio amplifier circuit, But I do strongly recommend the old style of wiring which is the use of laminated PCB board, Because it forms an excellent ground plain resulting in less hand capacity effects when tuning in the higher shortwave frequencies. Also do not overlook the advantage of using the valve style method such as aluminium cases and tag board.

General Construction Of The Receiver Please refer to picture 3 which is the circuit diagram and picture 4 the wiring diagram. The copper cladboard specially recommended for all these versions of the regenerative receiver is available from Maplin Electronics code WF41U and should accommodate all hardware and components.

The RF coils weather band switching is used or not are best mounted on the left hand side with the tuning capacitor in the centre. Also if band switching is used you must mount each tuning coil about 2 inches or 40 mm apart to avoid coupling effects and make sure that you keep wiring in the tuned circuits as short as possible, Particularly the SW3 high frequency coil. The other wiring is not as critical but do try to keep it as neat and short as possible. All Wiring of this receiver is supported by tagboards and points marked E are chassis earth return points in which all leads can solder direct to the copper board.

It must be mounted on veroboard and a 14 pin DIL holder is recommended to avoid the risk of damaging this IC when soldering. Also you must make sure this IC is wired or plugged into the holder with the correct polarity or it may be immediately destroyed.

Battery Switches Battery Switches Battery disconnect switches help manage the overall use of electrical power on board. They are used to connect or disconnect electrical devices from the electrical system. They help to prevent battery drain during periods of inactivity. They allow for a quick and easy way to shut down the entire electrical system in an emergency.

An optional key lock helps to prevent unauthorized use of the vessel. In addition to doing everything a battery disconnect switch does, battery selector switches permit battery selection of two or more batteries for specific purposes including starting engines, running accessories or even recharging. They allow for the use of one or more batteries in systems with one or more engines and facilitate putting batteries in parallel for emergency starting when one or both batteries are substantially discharged.

All Perko battery disconnect switches and battery selector switches are UL listed, ignition protected and CE approved. This means they have been tested and certified by a respected outside agency, are designed to be used safely in a bilge where explosive fumes may be present and meet all the requirements for use and sale throughout the world. Perko battery switches are designed for surface mounting. Standard duty switches have a bright red polycarbonate housing for safety with a large easy-to-turn black knob.

The housing of the heavy duty switches are red fiber-reinforced polycarbonate.
