I would suggest you try to find the manufacturer of your tachometer on the web and check out their support site and email them if needed for your particuliar vehicle. For instance below is a link to Autometer's Tech Tip web site however unless you own an Autometer Tach this may be useless to you. There are so many different ignition systems today that it would be difficult to explain each. So its best to get the info from the pro's. , EzForJesus
It's really easy. First you need to find wich wire on the tachometer is the coil signal. Take the black wire and put it on the ground of a 9V batterie then try all the other wires on the positive side of the battery until the RPM move. this is your coil wire. Go on the engine compartiment and find the coil. Start the car. Whit a test lamp try all the wire on the coil until you find the one who flash. Plug the coil wire (on the tachometer) on this wire and the black one on a nice ground. Finally plug the other wire(s) to a 12v source who works only with the key at the RUN position. And it's done
When I give mine a good beating, 6200 RPM would be it.
the redline on a tercel 91 fuel-injected model is 5,200 rpm, at 5,800 it will limit,
need to know how to hook up the wires on the engine on F-150 pick up to make a pro tach rpm gauge work
Easy!! Put it on the neutral position. Press the gaz pedal to the end. When it goes cut off note the RPM. It's the RPM cut off minus 500RPM
why doesn't my rpm gauge and temp gauge, fuel gauge not work
this question should be listed under dodge automobiles
Your engine is not running or your "RPM gauge" is broken.
while driving the rpm gauge work perfect, when start accelerating the rpm can not exceed 3 with interruption in the engine
The RPM gauge is connected to the same wiring on as all the lights on the dashboard. A faulty RPM gauge can be replaced but requires removing the whole dash from the vehicle.
