To fix a 12V diesel tachometer, first, check the wiring connections for any loose or damaged wires. Ensure the tachometer is receiving power by testing the voltage at the input terminal. If the connections are intact and powered, inspect the sensor or signal source, typically a magnetic pickup or alternator signal, for proper operation. If these components are functioning but the tachometer still doesn't work, it may need calibration or replacement.
The HJ60 repair manual I have is vague about tacho wiring. Some trucks used tacho pickup off the alternator winding before the diode plate, via an extra small wire connected into the alternator.The 2H, and presumably 12HT, have a magnetic pickup on the edge of the bell housing over the flywheel on the left hand side. It requires the magnet to be on the flywheel which mine does not have.

To connect the tachometer on a Mazda R2 diesel engine, locate the engine's tachometer signal wire, typically found near the alternator or on the ignition system. Connect the tachometer's signal wire to this terminal, ensuring a secure connection. Additionally, connect the power and ground wires of the tachometer according to the manufacturer's instructions. Finally, check the tachometer function by starting the engine and observing the readings.
you have to replace it
To hook up a tachometer to the alternator on a Massey Ferguson 175 diesel, locate the alternator's signal terminal, usually marked with a "T" or "S." Connect the tachometer's signal wire to this terminal, ensuring a secure connection. Additionally, connect the tachometer's ground wire to a suitable ground point on the tractor. Finally, reference the tachometer's manual for any specific calibration settings or adjustments needed.
To fix the tachometer on a Nissan GA14 engine, first check the connections between the tachometer and the engine's ignition system, ensuring that all wiring is intact and secure. Inspect the tachometer itself for any signs of damage or malfunction. If the wiring is fine, test the tachometer with a multimeter to determine if it’s receiving the correct signals from the ignition coil. If necessary, replace the tachometer or the ignition coil to restore proper functionality.
To fix the tachometer on a 1999 Isuzu Trooper, first check the vehicle’s fuses to ensure none are blown. If the fuses are fine, inspect the wiring and connections at the tachometer and the engine’s ignition system, as loose or damaged wires can cause issues. Additionally, consider testing the tachometer with a multimeter to see if it’s receiving a signal. If these steps don’t resolve the issue, the tachometer may need to be replaced.
There is a fuse for the tachometer in this model. Under the hood on the driver's side there will be a fuse box,Êopen this box and it will show the layout for all fuses.

I think the sensor are on the gearbox , and send it to the transmision ecu
To fix the tachometer in a 1996 Nissan 240SX, first, check the wiring and connections behind the gauge cluster for any loose or damaged wires. If the connections look good, inspect the tachometer itself for any signs of malfunction, such as a broken needle or burnt-out bulbs. You may also want to check the ignition system, including the coil and distributor, as issues there can affect the tachometer's performance. If all else fails, consider replacing the tachometer or the entire gauge cluster.
Yes it will unless u have a diesel engine
