If the RPM gauge drops to zero while driving, it typically indicates that the engine is stalling or has shut off, which could be due to several issues such as fuel supply problems, ignition system failures, or electrical issues. Another possibility is a malfunctioning RPM gauge or sensor. It's important to check for warning lights on the dashboard and address any potential mechanical issues promptly to avoid further damage.
That means you need to get toa gas station.
The temperature gauge in a vehicle can fluctuate while driving due to changes in engine load, speed, and coolant flow. When accelerating or climbing a hill, the engine generates more heat, causing the gauge to rise. Conversely, when coasting or driving at lower speeds, the engine may cool down, leading to a drop in the gauge reading. Additionally, variations in the cooling system's efficiency, such as the operation of the thermostat or the radiator fan, can also contribute to these fluctuations.
If it is your voltmeter that drops while the vehicle is running. Most likely the alternator isn't putting out enough volts.
speed sensor
It should maintain aprox 14 Volts, give or take 1/2 volt while engine is running.
Check your electric fan operation and coolant level. If the fan is not working, temp will increase at idle and will decrease when air moves across the radiator while moving.
It's probably the Voltage regulator inside the Alternator.
A drop in your revometer, speedometer, and temperature gauge while driving could indicate a problem with your vehicle's electrical system, such as a failing alternator or a weak battery. It might also suggest issues with the vehicle's Instrument Cluster, wiring, or sensors that provide data to these gauges. Additionally, overheating can cause a drop in performance, which might affect these readings. It's advisable to have your vehicle checked by a mechanic to diagnose the issue accurately.
To prevent the stomach drop feeling while driving, you can try sitting in the front seat, focusing on the horizon, avoiding heavy meals before driving, and taking breaks to rest your eyes and stretch.
Well, kinda need to know if it did anything else. If the vehicle continued operating at normal, probably a fault voltage gauge or regulator. If you actually lost all power, the whole thing would shut down. If it was a temporary loss of power, then it kicked back to normal, you're probably looking at a loose or faulty ground wire.
For drop C tuning, a common and recommended string gauge is 11-56.
For tuning to drop C on a guitar, a string gauge of 11-56 is recommended.
