Try a damping circuit.

This is stuff I have not worked with in 20 years. LOL. I can not draw this for you here, you can figure it maybe from what I tell you. \n(1) You want a circuit that has say 10V steered to four outputs depending on the control inputs. We will say the control inputs are 0 & 5 volts we are steering 10 volts. You are looking at a circuit with 7 lines. 1 input, 2 control and 4 outputs. The voltage to your controls has 4 possibilites.\n0&0 control volts input 10 volts to output line #1\n0&5 control volts input 10 volts to output line #2\n5&0 control volts input 10 volts to output line #3\n5&5 control volts input 10 volts to output line #4\nThat about all I can say here. May use AND, OR, NOR Gates??\n(2) Is even more complicated and I can not even begin to tell this in words. Hope this helps, I doubt it will, but, I tried.

u can go to library.alldata.com and be able to find the wiring schematic. or sometimes u can call a local parts store and they can print one out for you.

go to library and study your circuits.  do your own homework.

Try Chiltons auto manual.Im sure they have a web site. Good luck

In a purely resistive circuit, the power factor (PF) is 1 and you *can't* adjust it.\n\nAnd, since this is the 3'rd time you've asked the question and gotten the same answer from one other person and myself, do you even know what 'Power Factor' *is*?\n\n\nDoug

you got Ohm law : Ur=R*i(where i stands for current) and what's more, for the coil we have Ul=-L*di/dt . And for the condenser we have C*Uc=q and i = dq/dt.Now you have a differential equation with only one variable i.\n note: if the circuit is parallel then U should be a constant , in this case you shuold use U instead of i.Goodluck

the cpu fan has a sensor in it that tells the motherboard what speed the fan is spinning. the sensor can go bad and the fan will still work. your going to need to replace the fan. Most motherboards won't let the computer boot up with a 0 fan speed

What does this auto center do and where is it located?

It wouldn't be easy.\n\nPower supplies for PC's generally produce four outputs: +12v, -12v, +5v, and -5v. Some PC power supplies also produce +3.3v and -3.3v. These voltages are measured with respect to a ground of 0 v. \n\nYour car battery is probably 12v, which means that there is a total of 12v of potential between the + and - poles; so the cathode of your car battery gives -6v and the anode gives +6v with respect to ground. It's very easy to step these voltages down to +-5v and +-3.3v, just put the appropriate resistor into the circuit and there you are. \n\nBut stepping the voltage UP to +-12v is another matter entirely. For that, you will need a transformer of the correct size and winding. Further, you should be aware that most desktop PC's want to consume 100, 200 or even 300 watts, which may easily be more continuous power than your auto battery is designed to give.

There's a great article explaining thyristor operation and showing basic circuit diagrams here: http://www.ibiblio.org/obp/electricCircuits/Semi/SEMI_7.html\n\nThere was also a very good reference book called "SCR Manual Including Triacs and Other Thyristors" published by GE from the early 1960's into the late 1970's.  It's a highly prized source for many engineers, and you -may- be able to find one for sale, if you're lucky. (No, you can't have mine :-P )\n\nDo a Yahoo! search for "thyristor circuit diagram" and you'll get thousands of results. :)

one is grounded and the other to ur ignition module or distributer depending on wat year it is
