Erratic Tach Signal at Erwin Marlatt blog

Erratic Tach Signal. Electrical problemsone of the most common culprits behind erratic tachometer readings is electrical issues within the vehicle. The fix is to add a simple 47k ohm resistor (1/4 watt, 5% to 10%, rated to 500v) in the rpm signal wire from the coil to the tach. In some cases, the tachometer gauge itself is the cause of the inaccurate readings. For vehicles with tachometers on the digital display, the readings may not show up if the led screen becomes faulty or broken. Voltage fluctuations in the electrical system can disrupt the accurate operation of the tachometer. We carry a tachometer signal filter that is easy to install and works with most ignition systems. Erratic or inaccurate readings may be caused by wiring complications and electrical interference from other devices. Inspect the sensor for damage and ensure it is properly aligned. Voltage fluctuations and software glitches are two typical culprits behind tachometer troubles. This acts as a filter to. These fluctuations may stem from issues like a weak battery, alternator problems, or faulty voltage regulators.
