I would say the mechanic didn't re-install the tachometer wire ,whereever it goes on this motor,which I don't know. I would say the mechanic didn't re-install the tachometer wire ,whereever it goes on this motor,which I don't know.
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.
The transmission could have been rebuilt improperly, or the linkage could have been reinstalled incorrectly.
If it was rebuilt wrong, Yes
A tachometer that shows the wrong reading and get stuck sometimes could be caused by faulty wiring between the transmission and tachometer. It could be caused by a defective instrument cluster.
Green wire on the distributor is the tachometer pick up. Green wire on the distributor is the tachometer pick up.
Could be--valve not closing completely
If the oil pressure gauge and tachometer on your 2003 Trailblazer are pegging all the way to the right, it could indicate a malfunction in the instrument cluster or a wiring issue, such as a short circuit. Another possibility is a failure of the engine control module (ECM) affecting sensor readings. Additionally, a significant loss of oil pressure or an issue with the tachometer's signal could also cause these gauges to behave erratically. It's advisable to have the vehicle inspected by a professional to diagnose the exact cause.
Could be the tach is set for 6 cylinders?
A fluctuating tachometer while sitting still could be due to a dirty or malfunctioning idle air control valve, a vacuum leak, or an issue with the engine's sensors or computer. It's best to have a mechanic diagnose the specific cause to prevent any further damage to the engine.
If the tachometer on your XS1100 stops working, it could be due to a faulty or disconnected cable, as the tachometer typically relies on a mechanical or electronic signal from the engine. Additionally, a malfunctioning ignition system or a blown fuse can also disrupt the tachometer's function. Checking the connections and testing the cable for wear or damage is a good first step in diagnosing the issue. If these components are functioning properly, the tachometer itself may need repair or replacement.
The tachometer measures the number of revolutions the engine makes in a minute. This indirectly equates to the speed of the vehicle. Depending on the gear that the vehicle is in, you could determine speed with a tachometer. To determine your speed, you would need to know the gearing of the rear end as well as the circumference of the wheels.
mine slipped on the timing belt itself so check the timing first then work the fuses and then use a tachometer on the ignition coil if not it you might have a fried motor man
