The Fuel and Temperature gauges as used in the 1960 - 1965 Ford Falcon are very basic instruments whose operating principles seem to have gotten lost in this modern day era of digital electronics. In order to properly troubleshoot the circuits you will need an ANALOG voltmeter and 2 `D` cell batteries. It is best you perform all of the troubleshoo

ting techniques before ordering parts for repair as there is a NO RETURN POLICY on any electrical items. The circuit diagram demonstrates that both the Fuel and Temperature gauge circuits receive their operating voltage from the same Instrument Panel Voltage Regulator. So what affects one circuit will also affect the other circuit. I. E. If one gauge is inaccurate the other gauge may also be inaccurate. G‚Remove the screws that retain the instrument cluster to the dash. Disconnect the speedometer cable from the rear of the instrument cluster and pull the cluster forward. You should be able to access the rear of the cluster and lie it on the steering column. A towel would help prevent the column paint from scratches. Turn the Ignition Key to the "ON" position. Check the voltage on the "Green-Black" wire at one of the gauge connections. The voltage should fluctuate between Zero and Ten Volts. This is the same Voltage that will be seen at the connection of both sending units. Connect 2 "D" cell batteries in series so you will have a 3 volt output. Connect the battery output to the terminals of the Fuel or Temperature gauge. Connect the Positive Battery output to the "Black-Green" terminal and the Negative Battery output to the "Yellow-White" terminal. The gauges should read "Full" or "Hot" respectively. If not, replace the gauge. One item that is often overlooked is the Grounding System. The Engine and Chassis must both be...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
