You need some tools. Go out and buy yourself a volt test light for testing circuits. It’s really kind of hard to check anything without these instruments. These instruments will go a long way in keeping your jeep running in the future. In this part of the test the clip lead from the test light is connected to the – side of the battery or a good known ground. If it lights up then the ground is good.

When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again. This should answer important questions such as what the voltage requirements are for charging your battery and whether or not you should remove it from the vehicle before charging.
The Pirani gauge is a robust thermal conductivity gauge used for the measurement of the pressures in vacuum systems. It was invented in by Marcello Pirani.. Marcello Stefano Pirani was a German physicist working for Siemens & Halske which was involved in the vacuum lamp industry.
Low RPM turn on and charge Fits factory applications Low and high current applications Multiple finishes available But now that people are driving their classic cars more often, and upgrading them to be more drivable, they are also adding more electrical components so that driving them is more enjoyable. Some cars also have an air suspension system, meaning the compressor needs to keep that air tank full — and that draws on the electrical system more than ever was intended.
Upgrades to digital ignition boxes and alarm systems also add to the amount of wiring that is added to a vehicle; people are also adding electric cooling fans to replace the mechanical fan. So how do you upgrade an electrical system that was never designed for all of these accessories? Many factory alternators from the classic car era had gauge wires, which are not sufficient to handle higher alternator outputs.
One solution to the charging dilemma is to upgrade to a single-wire alternator that puts the power directly to the battery — and only when the engine is running. What Determines The Output? These alternators are designed to fit the factory brackets, so no special bracketry is required. We checked out Powermaster Performance and Tuff Stuff Performance to get a better idea of how to choose a one-wire alternator, and to learn more about them.
They will improve their effectiveness when the alternator is installed correctly, but when a amp alternator will suffice, amps will do very little other than empty your wallet more. Compact, but these alternators can provide big amps to power your electrical system with ease. Powermaster has technical bulletins that can help you determine the average amperage load of the accessories in your car, such as air conditioning, auxiliary lighting, high-powered stereos, etc.
This project started after I realized that I didn’t have the time to wait for the gauges to come back from several sources that I had contacted when I had the gauges out for my own refurbishing project over a year ago. I spoke to Morris and found him to be very customer focused and more concerned that I would get what I wanted done, than several other gauge repair facilities who could only say, “ship the gauges to us and we’ll call you with an estimate. Names such as Pertronix, Mallory, etc are among the most commonly used on these cars, although Morris can do a variety of conversions.
It would be best to specify to Morris what you are currently using for your ignition system and what you MAY plan to use in the future, should any special exceptions need to be made in calibration or wiring. Morris talked to me about the way that he performs the work and exactly what I would be getting for each price that he quoted.

Over torque of the spindle nut will lead to a very hot bearing very quickly. Duane But here’s the exact instruction from X Tighten castilated nut figure 17 to ft. Many references I’ve seen recommend 0. Checker had all the parts in stock and were cheaper than AutoZone. When you look closely at the inside bearings you see “Mexico” on them!! The outside bearings are made in Germany.
They have two different seals using the same number. The grease will leak out and there goes the bearing.. GeneD I think the jury’s still out on the final verdict.
Bellows[ edit ] A pile of pressure capsules with corrugated diaphragms in an aneroid barograph In gauges intended to sense small pressures or pressure differences, or require that an absolute pressure be measured, the gear train and needle may be driven by an enclosed and sealed bellows chamber, called an aneroid, which means “without liquid”.
Early barometers used a column of liquid such as water or the liquid metal mercury suspended by a vacuum. This bellows configuration is used in aneroid barometers barometers with an indicating needle and dial card , altimeters , altitude recording barographs , and the altitude telemetry instruments used in weather balloon radiosondes. These devices use the sealed chamber as a reference pressure and are driven by the external pressure. Other sensitive aircraft instruments such as air speed indicators and rate of climb indicators variometers have connections both to the internal part of the aneroid chamber and to an external enclosing chamber.
Magnetic coupling[ edit ] These gauges use the attraction of two magnets to translate differential pressure into motion of a dial pointer.
Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and ments used to measure and display pressure in an integral unit are called pressure gauges or vacuum gauges.
It must be capable of delivering the amount of current that the load is demanding. When electrical systems are designed the wire size is calculated for the specific requirements of the electrical components being used. When electrical components are added or upgraded the wire size has to be upgraded also. For example, replacing a low torque starter to a high grade torque starter will normally require the battery cables and possibly the battery to be upgraded.
When in doubt, always use a bigger wire. The higher the AWG number, the smaller the wire. For example, a 14 gauge wire is smaller than a 10 wire. The smaller the wire the greater the resistance to the flow of electrons and the greater the heat generated when the wire is conducting electricity. The heat can destroy insulation and even kindle a fire. The larger the amperage of a circuit, the thicker the gauge of the wire that is needed.
Think of wiring as a water hose.

I would suggest you try to find the manufacturer of your tachometer on the web and check out their support site and email them if needed for your particuliar vehicle. For instance below is a link to Autometer’s Tech Tip web site however unless you own an Autometer Tach this may be useless to you. Th…ere are so many different ignition systems today that it would be difficult to explain each. So its best to get the info from the pro’s.

Deciding in advance, where you want the gauge mounted and what circuit you will connect it to will make the procedure much easier. These steps apply to most aftermarket gauge sets and will help you install the unit in a matter of minutes. Park your car in a safe, level place. Turn off the power. Choose the best mounting location for your autometer volt gauge. A good place is under the dashboard, which makes it easier to route wiring away from plain sight.

You can see the letters stamped in the insulation material around the posts.
For your electric fencing project, this is absolutely necessary. You just cannot have a good, working electric fence without it. I moved my fenced area for the pigs farther from the house, so needed to extend the wire another 50 feet.
Wiring connectors assorted connectors and a 3 way connector Wiring schematic specific to your vehicle Wrenches assorted sizes Step 1: Park your vehicle and apply the parking brake. Your parking brake should be a pedal or a hand brake. If it’s a pedal, push it down until you feel the brake engage. If it’s a hand brake, push the button in and pull up on the lever.
Release the latch inside the car. Stand in front of the car and lift up the hood. Disconnect the negative battery cable. Position it away from the battery. Decide where you want to install the gauge. First, you need to see how the gauge mounts: If it has a screw mount, you need to make sure that it is mounted in a spot where screws will not hit anything inside the dash.

Sending Unit Extension Water Temp Sending unit The ‘new’ dash unit – ’66 gauge clusters used to be a dime a dozen at the swap meets. They were the bait that the vendor uses to tell you what kind of car he’s parted out and is selling. They can run anywhere from five to fifty bucks for the exact same unit. They are getting increasingly harder to find. EBAY regularly has them posted and typically go for between 20 and 40 depending on condition.
Look them over closely. Forget about the front bezel and the lenses because you’re going to replace them anyway. You’re after the internals and the back housing. Make sure the units are relatively clean, straight, not been sitting out exposed to the weather. Housings with rust on the back are typically not a good sign. You can find one out there that’s not rusty.
After you find your cluster, buy a fresh bezel, a new lens set, the paint, and 7 light bulbs.

The following instructions are for creating a MegaSquirt to Relay Board cable. It is for those who are creating their own harness. With both boxes mounted, measure the distance between them from DB connector to DB connector – this will be the length that you will cut the individual wires. If you are not using a Relay Board, allow enough length in each of your wires to reach the target component.

Two-contact test lights[ edit ] A voltage tester with three lamps to give an approximate indication of voltage magnitude The test light is an electric lamp connected with one or two insulated wire leads. By connecting the flying lead to an earth ground reference and touching the screwdriver tip to various points in the circuit, the presence or absence of voltage at each point can be determined, allowing simple faults to be detected and traced to their root cause.
For higher voltages, a statiscope consisting of a neon glow tube mounted on a long insulating handle can be used to detect AC voltages of volts or more. For low voltage work for example, in automobiles , the lamp used is usually a small, low-voltage incandescent light bulb. These lamps usually are designed to operate on approximately 12 V; application of an automotive test lamp on mains voltage will destroy the lamp and may cause a short-circuit fault in the tester.
For line voltage mains work, the lamp is usually a small neon lamp connected in series with an appropriate ballast resistor. These lamps often can operate across a wide range of voltages from 90V up to several hundred volts. In some cases, several separate lamps are used with resistive voltage dividers arranged to allow additional lamps to strike as the applied voltage rises higher.

Magnetic coupling[ edit ] These gauges use the attraction of two magnets to translate differential pressure into motion of a dial pointer. As differential pressure increases, a magnet attached to either a piston or rubber diaphragm moves. A rotary magnet that is attached to a pointer then moves in unison. To create different pressure ranges, the spring rate can be increased or decreased. Spinning rotor gauge[ edit ] The spinning rotor gauge works by measuring the amount a rotating ball is slowed by the viscosity of the gas being measured.
The ball is made of steel and is magnetically levitated inside a steel tube closed at one end and exposed to the gas to be measured at the other. It is accurate and stable enough to be used as a secondary standard. The instrument requires some skill and knowledge to use correctly.
