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...
Car Dashboard Display Running on empty? © iStockphoto.com/moori At a minimum, your dashboard display has a speedometer and a fuel gauge. In addition to those gauges, the display will feature some combination of a tachometer, charging system gauge, oil pressure gauge, and engine tempe...
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). However, with the onset of new reading systems, the use of digital tachometers has...
but used simple topologies, such as a bus topology where every device on the network was connected to a single bus, this meant all ECU’s were directly accessible on the diagnostics port and could communicate with each other. As CAN bus became...
The foundation of this unparalleled success was the world's first mass-produced car: the cheap, simple Model T, whose lovable quirkiness was matched only by that of its creator, company founder Henry Ford. Henry's decision to abandon his treasured "Tin Lizzie" after 19 years and a ...
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...
This means deer are really good at spotting movement from relatively far away and from a very wide field of vision. (Helpful for detecting a wolf trying to sneak closer from a distance.) However, when it comes to having clear, focused vision on something right in front of them, their eye...
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...
The Elantra's new digital gauge cluster is clean and simple with two traditional-looking instruments—a 180-mph speedometer on the left and an 8000-rpm tachometer on the right. In the center, you can choose to display more instruments, including gauges for boost and oil temp, a g-meter, ...
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...
