How do you get your trunk to close when the electronic motor goes out on a 1990 Oldsmobile 98?
We took the electric unit out of the trunk, disassembled it and wound the screw jack to the position needed to keep the trunk closed. This took a couple of times to get it right. We left the unit unplugged and now it operates as a regular, non-self-closing trunk. The electric release still works fine.

Firstly, there are a few meanings for the word ballast, and they are used in different contexts.
In an electrical context:
Electrically, It adds resistance to limit the current. In a fluorescent light fitting, the ballast adds resistance. Once the lamp conducts, it presents a very low resistance to the circuit and would draw too much current. The ballast coil also has reactance and provides a back emf pulse, to enable the lamp to fire (conduct) when it is interrupted by the starter.
In an a shipping context:
Ballast is used in ships and submarines (both new and old) to provide stability to the vessel within the water. Normally the trim of a boat in the water will differ whether it carrying a cargo or not, if the ship is lighter and higher in the water it is more inclined to roll from side to side in heavy weather. In order to prevent this ballast tanks are used in ships, these are then filled with seawater in to make the ship heavier (lower) in the water and less prone to tilting. Before the ship takes on cargo the tanks are pumped out making the boat "ride" higher in the water. Earlier wooden vessels also used ballast, but would use stones, rock or bricks for this purpose.
In submarines, ballast tanks are flooded with water or purged using compressed air in order to maintain neutral buoyancy, or to allow the submarine to ascend or descend.
In hydraulics/ irrigation terms:
Ballast tanks (sometimes called buffer tanks) are used in irrigation and plumbing systems to provide a buffer between supply and demand systems. A simple example of this is the water tank of your toilet. The system, when flushing requires a fairly substantial amount of water, the mains water supply of a typical house does not have this volume all at once, so the water is stored in a small ballast tank. When you press the flusher a larger volume of water that can normally be supplied by the house water supply is release - giving you a clean bowl.
What is more important - resolution or dynamic contrast ratio?
most of the cases the resolution is important when it comes to large screens contrast ratio matters!! i mean lik the very large plasma displays!!
Where do you have a 40 year old Hobart N-50 mixer repaired in the Chicago north-side area?
i'd call Hobart....i'm sure they'd be interested in anything of theirs that is still around after 40 years.
What is Canada's relationship to the United Kingdom?
both Canada and the united kingdom were ruled by the British.
What is the function of TV flyback?
The TV flyback transformer is obsolete in modern television sets and is not used.
In the old cathode ray tube (CRT) television sets the flyback transformer had two functions:
- generate a large and powerful current pulse to drive the horizontal deflection coil in the yoke around the neck of the tube to create a quick horizontal retrace between sweep lines
- using a large secondary autotransformer winding produce a very high voltage (i.e. 15KV to 100KV) rectified by a high voltage diode needed by the anode of the CRT to accelerate the electron beam
What two things must happen to cause an silicon controlled rectifier to fire?
You must have a voltage on the gate that exceeds the turn-on threshold of the SCR. Typically around 0.65v. Then you must maintain a minimum holding current from Anode to Cathode. Once turned on, the SCR will remain self latched in the on state until the current through the Anode and Cathode falls below the minimum self holding current.
A passive subwoofer doesn't have a built-in amp and will require the use of an amp.

What does within proximity mean?
it means to be nearby or close...proximity means close...so to be within proximity is to essentially be "even near"...i hope i helped :)
What determines the transformer ratio?
Transformer ratio, more correctly turns ratio, is the number of turns in the primary winding divided by the number of turns in the secondary winding.
What does 100 to 240 V mean for use in the UK?
If "100 to 240 V" is stated on the rating plate of a small electrical appliance, such as an electric razor or a plug-in power supply for something else, that means it is designed to operate on any voltage between 100 Volts and 240 volts.
* So the appliance will work if it is plugged into a 120 Volt household AC power supply in the US, Canada or elsewhere in the world which uses a similar supply
and
* it will also work on a 230 Volt household AC power supply in the UK or any other country in Europe or elsewhere in the world which uses a similar supply.
It would be a lot of trouble for me to try to explain the working principle of ground resistance tester since my English is no so good but fortunately I can give you the right internet address so you can download the exact information you need: www.dranetz-bmi.com/pdf/groundprinciples.pdf

What is digital object counter?
Digital object counter is a device which is designed to count the object which passing from above it or by touching it or whatever depending upon the method of getting signal from the transducer or smart devices. But main work of digital object counter is the counting of things or objects. it can be done by using LDR or THERMISTOR or VDR (these are used for sensing that a object is arrive or present here ) etc .
There are many factors to consider when looking for development engineers. Finding them is easy. A search of the Internet will produce hundreds of companies around the world. Choosing one can be much harder.
Look for experience in your market sector and discipline. Look at the size of the company to make sure they will cope with the projects. Ensure that they are willing to work to agreed timescales and standards. Know whether you will own all rights to the software produced at the end of the project.
These are just a few things to think about when choosing any design team. Put in the time and effort in the selection and it will be repaid well. Not spending time to research the companies will normally end up very costly.
It is an alarm to alert someone or something that the power is no longer working.
How do you get japaniez codes to work on an American game on the action replay ds?
The codes won't work cause those codes are onley capible for the Jappaneese games.
How do you use high powered Chinese appliances in the US?
You need to buy a transformer to convert the voltage to 110V.
