Usually a loose or failing switch will also cause the car to run poorly, but if the problem is very minor it can begin as an erratic tach signal. ... Look for corrosion, a broken wire, or a loose connection anywhere between the coil terminal and the tachometer. What would cause my sp...
In addition to those gauges, the display will feature some combination of a tachometer, charging system gauge, oil pressure gauge, and engine temperature gauge. Let's have a quick dashboard confessional that covers what each part does. The speedometer, one of the most frequently used tools, ...
Tachometers, in their most basic forms, are devices that measure the speed of an object. Most commonly, they measure the rotation of a mechanism, like the engine shaft in a car. Traditionally, tachometers are dials with a needle pointing to the current speed in RPMs (revolutions per minute...
A car generatoris a dynamo. It is able to produce electricity through the rotation of tightly wound fine wires in a magnetic field. This magnetic field is maintained by a fixed arrangement of magnets or electromagnets surrounding the spinning windings of wire. The current and voltage produced dep...
The Model T, known for its affordability and simplicity, propelled Ford to success, but the transition to the new Model A was costly in terms of both money and customer goodwill. Despite strong competition and the onset of the Great Depression, the Model A was a success, and Ford continued...
With open-loop sensors, drift caused by temperature, or any non-linearities in the sensor will cause an error. On the other hand, closed-loop sensors employ a coil that is actively driven by creating a magnetic field that opposes the current conductor’s field. This is the “closed-loop”...
inside the case. The large contact in the middle is where the coil wire goes (the wire that links the coil to the distributor cap. There is also a 12V+ wire that connects to a positive power source. The third contact communicates information to the rest of the car, like the tachometer...
A voice coil linear motor is a two-wire motor like a DC brush motor with no brushes. Choosing between the different types of motors depends on the application. As an engineer we can get support from our motion control distributors to help us select the correct motor for the mechanical ...
One of the most interesting things about car odometers is how the information is transmitted to the dashboard. Instead of a spinning cable transmitting the distance signal, the distance (along with a lot of other data) is transmitted over a single wire communications bus from the engine control...
The drive cable consists of a number of superimposed, tightly wound, helical coil springs wrapped around a center wire, or mandrel. Because of its construction, the drive cable is very flexible and can be bent, without fracture, to a very small radius. This is handy because the cable ...
