A new battery should read approximately 12. You can select a desired topic from the list below or go through all of them in sequence. The rate of failures due to vibration, flexing and bad solder joints is unacceptable to modern aviation safety regulators. Additionally, if it encounters rust or corrosion in it's path, it will start to seek out an alternative path if available. When the switch is in the 'Normal' position, none of the wires are connected and when the switch is in the 'Right' position, the Gray and Blue wires are connected. Any movement in the wires near this joint can cause the solder joint to become brittle and crack, eventually breaking off all together. Don't be an ass and complain about the lexicon.
. Spade Connector Another common type, especially in automotive. Here the meter is set to measure resistance in the range of zero to 200 Ohms. Only exposed portions of wires such as the connectors at each end can become corroded normally, and that corrosion can then spread down the wire, corroding the parts under the insulation as well. For information on licensing, contact the. Once you have located the wire that is causing the problems, trace the wire all the way through the wiring harness, then find brand new automotive-rated multi-stranded wiring in the same gauge or a lower gauge i. Lie detector manufacturers rely on this bit of trivia.
So if the meter switch is set to the 200K position, it can measure resistances ranging between zero up to a maximum of 200,000 Ohms. Simple Wire to Wire Splice: The best way to splice two simple wires together is called the Western Union Splice. If connectors are corroded, sand with emery cloth to remove corrosion and coat with vasoline or dielectric grease. In practice, the meter leads themselves have some finite resistance and this probably accounts for most of the non-zero meter reading. This is especially critical if you have added any electrical accessories. A setting of 2000 will allow the meter to measure resistance values ranging between zero up to a maximum of 2000 Ohms.
Because of the nature of their designs, alternators and generators normally fail for only one of three reasons: A Most common: a break in the windings of the coiled wire that surrounds the magnet. So what is a known good ground reference point? Make sure to read the instructions that came with the multimeter before attempting to use it on your motorcycle. The ones pictured on the bottom are the type you will most likely see. One advantage to the cheaper hand crimpers is that they usually incorporate a wire stripper into the handle. Start the motorcycle by whatever means necessary -- even push-starting if necessary. Motorcycle Classics is America's premier magazine for collectors and enthusiasts, dreamers and restorers, newcomers and life long motorheads who love the sound and the beauty of classic bikes. We then learn about Electronic Testing Tools in Chapter 3; Batteries in Chapter 4; then Charging and Starting Systems, Ignition Systems and then Fuel Injection Systems hey, they need electricity too you know! Synopsis A motorcycle s electrical system can be daunting to even the most adept home mechanic.
Wiring The wiring on a motorcycle is designed to carry power to the various devices that use it. Regardless, I strongly recommend first viewing the section as failures here have a very high rate of occurrence. First, make sure you strip enough insulation to leave yourself a good length of bare wire to work with. There are also silver solders available for stronger joints and lower resistances, but they have a higher melting point and are more expensive. Out in the open, they are constantly subjected to destructive elements like rain, sand, salt, dust, and ultraviolet rays. For heavy duty soldering, you can purchase a soldering gun kit like this.
After you analyze the results taken, you should be able to determine what the problem is and how to remedy it. A large one can also easily fling you 20 or 30 feet. Veteran technician Tracy Martin explains the principles behind motorcycle electrical systems and how they work. When troubleshooting any electrical problem on a motorcycle, keep in mind that the Conventional Theory of Electricity is used. So we have to be careful when making modifications or additions to the electrical loads on our bikes. While this theory has in fact been proven to be faulty, it is still used as a standard and therefore, you should follow it.
Here are a couple of simple examples. Even if you just jumpered two wires across a battery, then the wires would then become the load as well as a conductor and they would consume electricity to produce heat. Do all three troubleshooting tests if this section applies. Battery The battery on motorcycles is a smaller version of the battery in cars, because the power draw of motorcycles is less than that of cars. Part of that difference is the insulation around the wire: by design, it must be able to resist oil, gasoline, fumes, heat, sunlight and vibration in ways that home electrical wire never does.
A simple voltage test doesn't tell you much as even a near dead battery can show full voltage, but as soon as a draw is placed on it, it will drop right off. Furthermore, water can exacerbate the problem, by creating a temporary circuit for electricity to flow through from a bare wire to other metal on the motorcycle. Soldering There are four basic concepts to understand about soldering that many people do not realize. These are just basic crimp pliers and you have to control the pressure on the connector yourself. This will help us generate some revenue and to make it easier for you to purchase products while helping to support webBikeWorld. Instead, I will just suggest a few simple preventative measures to keep your battery working well and lasting a long time. Motorcycle Electrical Systems: Troubleshooting and Repair explains the principles behind motorcycle electrical systems, describes how they work, and reveals proper testing tools and techniques to find out where the problem's source is.
