|---|---|---|
| El tacòmetre no s'encén. | No power to the red wire; poor ground connection. | Check 12V power supply and ground connections. Ensure ignition is on. |
| Display shows "0" or incorrect RPM. | Incorrect or loose signal wire connection; incompatible signal type. | Verify the signal wire is correctly connected to the RPM source. Ensure the signal source is active. Some vehicles may require a tach adapter. |
| RPM reading is sluggish or jumps erratically. | Interference in the signal wire; poor signal quality; loose connections. | Ensure signal wire is routed away from high-voltage cables. Check all wiring connections for tightness and proper insulation. |
