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...
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 temperature gauge. Let's have a quick dashboard confessional that covers what...
The tach instructions said to wrap the red wire around the cable 3-4 times. The tachometer worked, but the idle was erratic. I eventually added a couple of extra turns to make the reading more stable. I made a mount for the Tiny Tach from some leftover 1/8" plywood. I could have ...
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...
the only change necessary was the addition of chevron brackets at the start and finish of the frame. SuperSniffer operates in a similar manner to Wireshark; it displays a live feed of data with a number of coulombs which give statistics about the data, the important coulombs being the CAN...
Figure 1. Tachometer-output waveform in 3-wire fans—ideal, and under PWM control. In order to be sure of a correct fan speed reading under PWM control, it is necessary to periodically switch the fan on long enough to get a complete tach cycle. This feature is implemented in a number ...
1 question I get many, many times a day right here up front. Why didn't I just use an automotive alternator on my wind turbine? Automotive alternators need to spin at very high speed to produce useful amounts of power. Most wind turbines don't spin fast enough for them to work. ...
Though Ford replaced pistons by the thousands to ease owner worries, the engine difficulties hurt sales. But they'd be cleared up soon enough, and the V-8 became known as a reliable powerplant that could stand considerable "heating up." Hot rodders loved it. Fords looked more flowing for...
Typical shunt measurement hook-up in a simple circuit We can measure this drop and applyOhm’s lawto calculate the current. Graphical representation of Ohm’s Law Ohm’s law describes the relationship between voltage (V), current (I), and resistance (R). If we know two out of three of...
If you only have a budget of $50 to fight deer, someone telling you to put up a new $10,000 wood fence isn’t very helpful. Don’t worry: there are plenty of methods to keep deer out of your garden and yard that are very affordable!
