What is the difference between tachogenerator and tachometer?
A tachogenerator is is an electric generator that generates a voltage that is accurately proportional to the speed of the shaft. Generating a voltage proportional to the speed is an inherent characteristic of all generators, but tachogenerators are specifically designed to provide an accurate signal over a specified range of load currents and operating temperatures. The output signal from a tachometer generator(tachogenerator) is often used to provide feedback to improve the regulation of an electric motor speed control. A tachometer is an instrument that measures and displays rotational speed. An electric tachometer combines the tachogenerator with a voltmeter that has the dial marked to show speed rather than voltage.
Receives the weight of the body when sitting?
When you sit, the weight of your body is distributed between your buttocks and the chair you are sitting on. The amount of weight on each varies depending on your posture and how you distribute your weight while sitting. On average, when sitting, about 60-80% of a person's body weight is typically supported by the chair.

Why is your Bonneville shaking while sitting still?
If your Bonneville is shaking while sitting still, it could be due to several reasons. Common causes include an unbalanced or damaged engine mount, which can lead to excessive vibrations, or issues with the idle speed or fuel system affecting engine performance. Additionally, a faulty or misfiring spark plug can also cause rough idling and shaking. It's best to have a mechanic diagnose the issue for a proper fix.
How do you fix a tachometer that bounces while driving on a 1994 accord.?
replace the ignition coil. There is a resistor inside the coil that fails over time and causes 2 problems. 1 the transmission may fail to properly lock the torque converter and 2 will cause the tachometer needle to fluctuate wildly, esp when it is hot outside.
When car is in park should tachometer read zero?
No, because the tachometer actually reads the rotation of the engine, not of the wheels and therefore reads about 500 RPM while in park.
