Temperature gauge goes up and down from 90 to , completely randomly sometimes it doesn’t happen and sometimes it does, no difference if i drive , or stand at a traffic light , or drive smooth or hit the road hard. My car is an aud s6 model 5. Than problem occured after i had a blown gasket due to a malfunction of my thermostat couple of month ago.

Gasket has been replaced at that time but after hundred km without any issue , i am facing this constant problem of the temperature gauge going crazy and for whatever reason it comes from 90 steady up to in about 30 to 40 seconds and then it comes back down while im still driving, and then all the cycle again , up and down up and down , sometimes more than and soemtimes less. The engine is not over hitting , coolant is not boiling ,cooling system pipes are not hard and can be pressed bare hands.

The system has been already bleed properly and filled back with a special vacuum to avoid any air in the system.

May 27,  · Just got my water temp electric gauge and not sure how to hook it up looks simple enough but not sure if I need to buy other stuff? Only has gauge 2 brass fittings and light with small wires any pics of how any of u guys have it hooked up or maybe a link in here in how to wire this gauge up?

History[ edit ] Although Evangelista Torricelli is universally credited with inventing the barometer in , [1] [2] [3] historical documentation also suggests Gasparo Berti , an Italian mathematician and astronomer, unintentionally built a water barometer sometime between and Galileo responded with an explanation of the phenomenon: Galileo’s ideas reached Rome in December in his Discorsi. Raffaele Magiotti and Gasparo Berti were excited by these ideas, and decided to seek a better way to attempt to produce a vacuum other than with a siphon.

The bottom end of the tube was opened, and water that had been inside of it poured out into the basin. However, only part of the water in the tube flowed out, and the level of the water inside the tube stayed at an exact level, which happened to be What was most important about this experiment was that the lowering water had left a space above it in the tube which had no intermediate contact with air to fill it up.

This seemed to suggest the possibility of a vacuum existing in the space above the water. He proposed that the weight of the atmosphere, not an attracting force of the vacuum, held the water in the tube. In a letter to Michelangelo Ricci in concerning the experiments, he wrote: Many have said that a vacuum does not exist, others that it does exist in spite of the repugnance of nature and with difficulty; I know of no one who has said that it exists without difficulty and without a resistance from nature.

In today’s modern vehicles, the coolant temperature sensor is what tells the car’s computer the current engine temperature. It works to help start the vehicle on cold days and keep it running smoothly, while also keeping the temperature regulated so it does not overheat. In older cars this would be known as the choke. When the coolant temperature sensor is not working properly the car will run sluggishly and could overheat. Replacing this sensor is an easy project that can be done in your own garage or on a flat driveway.

Step 1 – Open Car Hood On a newer car, locate the hood release beneath the steering wheel inside the car. Next, put your hand in the gap under the center of the hood to feel for the latch. Push it to the side and open the hood. Use the hood support to make sure that the hood is secure and will not fall on you when you let go of it. Step 2 – Locate Coolant Temperature Sensor The coolant temperature sensor is located on the front of the engine block.

Most of the info below curtesy of Dave Loveman Tachometer The tachometer plays a very important role in engine ensuring proper engine cooling and performance. An engine allowed to over rev will run a lean fuel and can result in engine overheating and possibly engine failure due to seizure. If the engine is not allowed to rev up to its proper RPM this can cause engine overheating, or engine failure due to the engine not being able to burn the fuel they way it was designed to.

A pilot taking off on an engine that can only develop RPM can attest to the fact that his engine will loose power and eventually quit. So what role does the tachometer play in all this?

In today’s modern vehicles, the coolant temperature sensor is what tells the car’s computer the current engine temperature. It works to help start the vehicle on cold days and keep it running smoothly, while also keeping the temperature regulated so it does not overheat.

When jumpstarting a car you essentially give the dead battery just enough boost to start the engine and then rely on the alternator to charge the battery the rest of the way. When using a battery charger, you allow the battery to charge all the way before it will be used again. This should answer important questions such as what the voltage requirements are for charging your battery and whether or not you should remove it from the vehicle before charging. There will be a manual with your battery charger that provides details for the appropriate use of the charger.

Working in a well-ventilated area will help dissipate the hydrogen gas that batteries generate from the sulfuric acid within their cells. Also, make sure to keep any other volatile substances, such as gasoline, flammable materials, or ignition sources flames, cigarettes, matches, lighters away from the battery at all times. Glasses, gloves, and other protective gear is a good precaution. Hydrogen released within the battery quickly converts to a gas and expands, this can cause the battery to explode if venting mechanisms fail.

These accessories draw power from the battery and should be turned off before removing or charging the battery. Most batteries will be found either under the hood of the vehicle or in the trunk. It is also possible that your battery may be under the rear seat, and sometimes the battery can only be accessed from underneath the side of the car. There are a few ways to tell which is which: Compare the diameters of the battery posts. For most batteries, the positive post is thicker than the negative post.

When the pressure reaches 6 psi, the switch goes on and the oil pressure gauge goes from zero to mid-scale. Neither of these stock gauges gives true readings or any warning of developing problems. Aftermarket real gauges do that.

High accuracy automatic tide gauge High resolution automatic tide gauge Common applications[ edit ] Tide gauges have a practical application in the shipping and fishing industries where low or high tide levels can hinder or prohibit access to shallow bays or locations with bridges. To this end, many industries have installed private tide gauges in ports across the country and also rely on government agencies such as NOAA.

Data collected from tide gauges is also of interest to scientists measuring global weather patterns, the mean sea water level, and trends – notably those potentially associated with global warming. Modern gauges[ edit ] In recent years new technologies have developed allowing for real-time, remote tide information to be published online via a solar powered wireless connection to a tide sensor.

Ultrasonic sensors [7] have already been deployed to great effect and the data is regularly broadcast via Twitter and also displayed online. From successive instruments were used as tide measuring technology developed. This system is now obsolete at Fort Denison but maintained as a museum exhibit. To the right of the large pipe in the well is an enclosed pipe which rises to the active modern system.

How to Wire Up a Yamaha Outboard Gauge

Bag of parts inside the box: The instructions are simple and easy to follow. Loosen the hose clamps on both carbs and remove the airbox. Remove the resonator and block the open holes from the removed resonator with a rag. Locate the temperature sensor in the cylinder head.

Wow, interesting post. I have 48 8N (front mount distributor and no proof meter), and it has the water temp sensor mounted in the upper radiator hose, and the gauge .

How to Wire a Temperature Gauge by Chris Stevenson A temperature gauge is one of the most important sensor gauges on any vehicle with an internal-combustion engine that uses a radiator and cooling jackets. Engine temperature directly affects combustion and moving internal parts. Without a temperature gauge, the engine would be subject to various modes of heat without the operator’s knowledge, and this could lead to bearing failure and engine seizure.

A vehicle owner can wire a temperature gauge in his or her vehicle in a driveway or garage. Set the emergency brake. Raise the hood and disconnect the negative battery cable with a socket. Refer to your owner’s manual for the location of your existing temperature sensor wire. Some are connected to the top of the thermostat housing, attached to a sensor probe.

Other wires can be found in the side of the engine block, where the sensor probe screws into a mounting flange. Make sure no components exist behind the mounting location. Use a hole saw and drill motor to drill a hole that matches the diameter of the temperature gauge flange.
