outboard motor tachometer wiring

If the outboard engine does not have a Tachometer, the instrument can be replaced directly. If the engine has a Tachometer and a speedometer integrated directly , attention must be paid to the replacement . The speed ratio of the replaced instrument must be the same as the original one. Otherwise , it may be inaccurate or the instrument may burn. If conditions permit , it can be installed by a professional person . After all , it is modified and it is safer to go to a professional site, and it will not be very expensive . When wiring the outboard motor Tachometer, the green line is connected to the rack, the black line is connected to the positive output of the ignition switch , and the rest is generally connected to the pulse low-voltage line of the large wire package.

Speed is a physical quantity that represents the ratio of the number of revolutions of a rotating object to time. In engineering, it is usually expressed as speed=number of revolutions/time, and is an important parameter for describing the rotational motion of an object . Electricians often need to measure the rotational speed of motors and their driving equipment , and portable outboard motor Tachometer is used . Outboard motor Tachometer is an instrument used to measure motor speed and linear speed. There are many kinds of Tachometer, and portable ones generally include mechanical centrifugal Tachometer and digital electronic Tachometer.

To understand the function of the outboard motor Tachometer, you must understand the working principle of the outboard motor Tachometer, which is actually a speed sensor on the engine. When our engine starts working, this signal will be transmitted to our car's brain through a chopper, and finally converted into an electrical signal, which is reflected on our speed dashboard. The faster the speed, the more pulses generated, and the higher the value at this time. By understanding this issue, you probably understand its purpose. The first thing is to tell us that the car's engine has already started at this time, after all, some cars nowadays do not have significant vibrations when starting, and sometimes they cannot be detected without paying attention. The Tachometer can tell us that the engine of the car is already running. Under such circumstances, we should change gears in time. To avoid damage to our engine caused by unreasonable operation.
