GM Muscle Car Tach Voltage Requirements - Pit StopA tachometer measures the number of times an engine's crank shaft rotates per minute RPM. For any engine, the RPM determines how much horsepower and torque is being produced at any given moment. Connect a tachometer to an engine and know when the engine is running at peak performance and when it may be working too hard. Too many engine revolutions will create excess heat, and reduces an engine's reliability. Protect any engine from excess wear and tear with the RPM data an easy to install tachometer can give you. Work in a well-lit area with access to the equipment you need once you have begun to connect a tachometer to your vehicle. Raise the hood and disconnect the negative battery cable from the battery and keep it from coming in contact during tachometer installation. Locate the ignition coil and clean the negative side connector and any adapters that may be present. Remove any oxidation or debris from this location where the tachometer sender wire will be secured. Find a good place to pass a wire through the firewall in front of the driver's compartment. Position the tachometer over the center of the steering column and fasten it securely using a mounting clamp and bracket fitting to the steering column of the vehicle. The tachometer will have wires coming from the back of the gauge. One is a ground wire, one is a power supply sire, and one connects the vehicle's ignition system either via the ignition coil or through an electronic connection with the vehicles computerized ignition. A system without a distributor will need to connect to the electronic ignition. Check with the gauge manufacturer for the GREEN wire connection path that suits the ignition system installed in your vehicle. The steps for the power supply and ground wires on all tachometers are the same. Tape together the wires that are protruding out the back of the gauge until the wires meet the dashboard. Secure the wires under the dashboard with tie wraps or by using existing harness paths to run the wires in conduit that houses existing wires. Find a pathway for the green wire to run through the firewall in front of the driver under the dashboard. Protect any wires from chaffing inside a firewall hole by protecting it with a rubber grommet and silicon gel. This makes the wire safe and seals the hole from the outside. Run the power supply wire to the fuse panel and tap into a fuse with a fuse tap. Find a fuse that operates on the turning of the ignition key. When the key is turned and the auxiliary power is supplied, the tachometer should also be lit for use. The ground wire must be secured in a paint free connection with the major parts of the vehicle. A great place to ground any gauge is at the mounting bracket for the pedal assemblies. Gas, brake, or clutch mounts are a great place to loosen a nut and insert a ground wire for an auxiliary component or electronic device.

Under the driver's seat, they is a single slot which is used for timing by the mechanic, you can just connect it to it. As for power for the light, just go under the dash and spilt connect to one of the live wires. Asked in Dashboard Lights and Gauges Does the tachometer work off the coil? It can also pull the signal from a spark wire. Asked in Chevy How do you hook up a hei distributor with external coil to a tachometer? The green wire from the tach goes to the negative side of the coil. Asked in Mitsubishi Trucks Where does tachometer wire hook to on mighty max ? It goes to the top wire on the coil, the one that usually has a cover over it. Asked in Acura Legend Why won't my 87 acura tachometer work and could it be affected by a bad ignition coil? A bad ignition coil can cause your Acura tachometer to quit working. A bad tachometer cable or ground wire can also cause it to quit working. TRy on the neg side of the coil. Mounted to the drivers side strut tower. Connect the green wire to the negative side of the coil. Asked in Dodge Dakota How do you hook up a tachometer on a 98 dodge Dakota 3. Since the truck is fuel injected, you will likely have to find a way to wire it in with the connector on the coil. Kyrasis6 Mazdatruckin.

How to Connect a Tachometer
I was suggested this website by my cousin. I'm not sure whether this post is written by him as no one else know such detailed about my problem. You are incredible! I've tried this permutation procedure and found it works to my aftermarket tacho meter, although my wiring has different color coded. But then my bike is loosing power. No problem if sensing wire disconnected from ignition coil. It seems that tacho sensor is drawing too much electric current from the coil. Any suggestion to solve that problem?? Thanks a lot for sharing your cloud data, Mikey. Hi Mikey. I think you need to build a transistor circuit to connect sensing wire to coil. Transistor base draws only a few milliamperes current for activation. You will need to find out base resistor value to adjust transistor current to match with tacho sensing current. The transistor is working like a relay switch to supply current for tacho to sense engine speed, and that relay switch is controlled by coil or igniter. Rgs, Heru. Hi guys I used rpm aftermarket for my motocycle 4 stroke cc. Why should i do. There is no direct connection between tachometer system and transmission system. But may be your motorbike has electronic gear indicator. That indicator may steal some electric current and affect your tacho. Tachometer needs a very good ground wiring to ensure a steady measurement. Try to ground negative your tacho directly to negative pole of battery. Do not ground on the frame, do not use a common ground wire. Possibly that common ground wire is already overloaded. Possibly you are needed to check the positive wire also, try to connect it directly to battery positive pole, not via ignition switch. Check also wiring system, remove fairings and covers to check wire connections. Hopefully you will find something loose. Your positive comment will be highly appreciated to improve this site.
