it is a device that converts mechanical into electric measurements. it measures velocity. there are many types: electrical, mechanical, thermo-electrical... for example the mechanical tachometer converts the rotation motion into translation motion with the help of an axis so you can read it on the scale of the tachometer. sorry for not being so good at explaining this. hope somebody will be more documented.
Yes , there was a mechanical gauge cluster and a mechanical gauge cluster with tachometer - but I'm sorry I don't know if they can be interchanged
You don't. A mechanical tachometer can only be used with a tach drive distributor. Every automotive parts retailer offers tachometers that can be used with the newer hei ignition.
The Mazda tachometer and the speedometer have separate cables. The tachometer cable probably does not work properly. Change the tachometer cable.
it sure would work.. behind the dashboard are plugs for each function. one for tachometer, one for speedometer, fuel, water temp. ect.. if your new dash doesn't have a tachometer it will not interfere with the speedomet aspect of it. but you will not have a tach obviously. that sucks kid
One possibility is that the tachometer connections to the circuit board of the cluster have become corroded. It is also possible that the tachometer has just become worn out and needs to be replaced.
A tachometer is an instrument which is used to measure the revolution speed of any rotating object such as a shaft or motor. It has it uses in the marine engineering field as well and is used to gauge speed of marine diesel engines on board ships and whether they are rotating in the ahead or astern direction. In this article you will learn about the working principle of a tachometer
rev counter not working
because they are broken.
There are several things that can cause your engine to misfire and the tachometer to not work properly. The most common cause is a malfunctioning vacuum hose.
If the tachometer only works a few times a year the VSS is malfunctioning. This can occur when oil is spilled on the unit and messes with the sensor. Cleaning the sensor will allow the tachometer to work properly.
A bad ignition coil can cause your 1987 Acura tachometer to quit working. A bad tachometer cable or ground wire can also cause it to quit working.
Replace the dash cluster that's what it sounds like to me since your tachometer and speedometer both don't work
