A mechanical tach will register 1 engine hour for every 100,000 revolutions. At 1666.6 rpm it will register 1 hour for every hour run. At 800 rpm it will take two hours of run time to register an hour.
In my opinion this was a more accurate method of measuring engine wear but is rarely used any more.
10 hours on the tach means your piston went up and down 1 million times.
A joule is a unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
100 centimeters in one meter.
(any unit of force) times (any unit of distance) is a unit of work and energy. (any unit of power) times (any unit of time) is too. newton-meter foot-pound watt-second joule kilowatt-hour BTU calorie horsepower-hour inch-ounce ton-furlong
Work is the exertion of force overcoming resistance or producing molecular change. Joule is the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour. Joules measure work.
kilometer or meter. Either will work.
It should work. I have a 94 w/o a tach and put a LE version cluster with tach in. Works fine. There should still be a tach wire grouped into the harness plugs. Just unplug your old one and plug in the new one that's it.
It should work ok if the wire for the tach under the hood is connected and I don't remember which one it is.
Tach is driven by a motor signal, speedo is from the trans the sensor is bad on the transmission
Bad white wire
The tachometer is fed from the distributor coil. High voltage spikes are filtered on the wire to prevent damage to the electronic display. There is a tach filter attached to the intake manifold. Replace this filter and your tach will work again. Mid-America Motorworks Part #618-561
It does not have a fuse, the speed sensor works the speed-o-meter \ \ I disagree, because the Radio fuse , in the fuse box under the hood will work the speedometer, Tach, and Message center
MSD had a module a few years back that would convert a tach signal. Not sure hear da rumor about using a wire off the obdii port, but never seen anyone with a mitsu do it and work. Have seen the MSD tach adapter work superbly.
Yes, however, the six cyl tach is different from the eight cyl tach. It will work but the RPM display is wrong.
bad ground or bad sensor or a short
For any of you who may have been watching this question, I'll give you the answer myself. The answer is YES. After purchasing the one with the factory tach and installing it, everything works like it should.
There should be a tach output connection on the side of the box somewhere, you just plug your tach pickup into that. If it doesn't work you'll need a MSD tach adapter. I'm unsure of the part numbers but there are 2 different ones, it depends on what you used to wire in your ignition. If you used the white wire there is one and if you used a magnetic pickup ( green and violet wires ) there is another one....MSD-8920. I have a sunpro tach and I had to go out and buy an adapter to make it work...for about 50 bucks.
It is similar to frequency . IT reds Time in close contac.
