The green wire goes to the negative side of the coil. The yellow wire is probably for a light in the dial. You'd want to connect it to a power source that comes on when the headlights are on. The red wire should be connected to a source that is live anytime the key is in the on position.

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 1987 Acura tachometer to quit working. A bad tachometer cable or ground wire can also cause it to quit working.
How do you install a basic rpm gauge to a mini bike motor its a 6.5 gx 200cc Honda clone engine?
Get an RPM meter (tachometer) for 1 cylinder 4 stroke engine to match with your engine. Connect ground wire from RPM to body, usually black colored wire. Connect power wire to ignition switch, make sure it is connected to 'ON' position of switch, this wire usually with yellow insulation. Connect green wire to coil negative terminal, this terminal is connected to contact point or ignition trigger system, the wire from tachometer is usually with green insulation. Start your engine and check RPM reading.
Will a burned out tachometer on your 66 Mustang cause car not to run?
If that 66 Mustang still has the original ignition system and the wire feeding the tach from the negative side of the ignition coil is shorted to ground, then yes the car won't run.
When hooking up a tachometer where do you hook the green wire to?
The green wire should be the ignition(-). Do not confuse it with the regular ground. Check your manual where to find your diagnostic connector( the one they put a jumper on for smog check, and where the diagnostic codes are checked); it is usually in the engine compartment, or maybe under the steering wheel.It is usually covered by a cap that says DIAGNOSTIC. Somewhere in or around it there should be the IGN- hookup. Some other possibility would be to check for the ignition- cable coming out of the distributor(that is if you have a distributor). My 91 Toyota has both, but I hooked my tach to the IGN- right besides the diagnostic connector in the engine compartment. WARNING; my tachometer says that when the tachometer is hooked up, never let the tachometer ground itself( it means it should never touch the chassis or any metal, and also that the cables going to the tach should be VERY WELL SHIELDED!!); otherwise it would ruin the coil of your car. That also means be careful with the cable not getting frayed or where you place the screws if you hook the tach to the chassis.I would recommend hooking it to a plastic part of the console, or place it over a rug or rubber glove so that the tach does not touch ground(chassis).
When it was raining hard and damp your engine cut out why?
check your ignition system for openings where moisture is causing your spark to ground
What are symptoms of a ignition coil?
A bad ignition coil normally won't allow your engine to start given there is no spark. If it is starting to go bad, it causes misfiring which can be noticed as a stutter, or random shake of the engine. Check the ground of the coil before replacing it.
Tachometer jumping around on a 97 Chevy Tahoe?
bad ground wire at the coil probably
How do you add a tachometer on a 1985 Chevrolet Caprice Classic?
On the distributor cap where the wiring hooks up is a terminal that says tach. Install the red wire to it and the black or ground wire to a suitable ground. Sometimes the tach has a green wire that connects to the white one coming from the ignition coil plug side that has 2 wires
Why does the tachometer jump around and the engine cut out on a 1995 Honda Accord V6 in all weather even after replacing the ignitor module?
It could be a bad cap, rotor, pickup coil/reluctor, or a loose ground.
What is the mesh wire that goes from the lower back of engine on the passenger side to frame it is torn on my car so does not connect to anything?
It is a ground strap to ground the engine block to the frame. a broken ground strap could result in improper electrical grounding for ignition and other electrical parts
On a Dodge Neon how many ground wires are there on the engine and where are they?
There are three ground wires to the engine. One goes from the Strut Tower to the back of the Cylider head left hand side (front) of the engine. Another goes from the Strut tower to the top of the engine mount. The third one is on the back of the head on the right hand side. This ground has a square black transistor on it and grounds the ignition system.
Can a bad ground on the coil result in no power to the ignition?
Maybe With out make model and year info here is a back ground answer. Most Modern Electronic Ignition systems operate by controling the ground for the ignition coil. These ground conections are "Common" or all hooked together. If there is no ground for the coil, there is a good chance none of the ignition is grounded correctly.
