Some computer memory setups come with fans that fit over the top of the memory sticks. Accordingly, different may use different number of power wires: see the pinout diagram to the right. Computer Connection Diagram There are a lot of cables involved when getting a computer connected and ready to run. The computer has many pins which connect to the various components. Here is a wiring diagram that can help you see where the wire is headed in the circuit and which pin number in the connector on the computer side. Usually you can get it from the 4 pin molex connector don't know which color - search it. Do not use it for an application other than failure monitoring.

First, identify the different cables that are attached to your case. Once the main connectors have been removed check the pins for rust or corrosion and clean as necessary. Figure 32: Installing the alternate 1x4 power connector Some power supplies can vary the fan speed for enhanced cooling or decrease the speed for quiet operation. I tried to put the yellow directly to the digital or pwm pins but it will not start. Typically, the motherboard is required to pull the pin up through a resistor, with the fan connecting it to ground once or more per revolution.

Over time engine vibration and road conditions such as heat, rain, snow and the natural aging of wiring can cause these connections to become loose, broken, damaged or corroded. The tacho signal from the fan sinks to ground for every revolution, the input on the motherboard is pulled high. In this guide will be testing the camshaft angle actuator and position sensor wiring because a code for the actuator and sensor circuit is present and they both have already been replaced. This means with the old 20-pin style you can't get more than 18A from 3. Case connections differ by manufacturer.

Again it is not needed, but it's good to have for reference. These will be small 4 pin connections that you can plug the smaller fans into. Otherwise, only 5V standby voltage will be present. Then, if you have 2 fans on the back of your case, you can string them together to the same power supply connection, like you would do with Christmas lights. Also, if you want, search for Pulse Width Modulation on the web - it's the same method used in Digital Amplifiers for audio. This will test the resistance in the wire if any.

It is a good idea to spray electrical cleaner across these terminals and on the connectors. You can buy an adapter that turns a 20 wire connector into a 24 wire connector, but if the power supply circuit doesn't provide sufficient power, it won't help. First we will check to see if the actuator is getting power. Printer Cable 25-pin Connector Pin-Out Chart. Be sure and snug this cable tight with the thumb screws provided on them because a loose connection will cause big headaches and can possibly cause monitor failure. This voltage is supplied by the computer or a fuse when the system is turned on.

All you need to do here is match up each wire with its pin assignments. Pin 1 starts at the other end, just inside one of the ridges. Answers given on other internet sites to similar questions by other posters were conflicted. The connector is keyed so that it can only be inserted in the proper orientation. Most newer computers do not have modems anymore but if you do have one in yours, it can still provide phone access and is useful to use as a Fax.

The keyboard port is purple and the mouse or other pointer device is green. The 24 wire receptacle on this particular Intel motherboard accepts the 20 pin connector, and it's keyed so it can only be inserted in the proper location, to one end of the receptacle. This will be the terminal used for testing. I normally would wire the red and black to positive and neg respectively and ignore the yellow altogether. These diagrams reflect the front view. Thank you if You can help me more. Otherwise, you can use screws that look like this to connect the fan to the case.

These connections must be clean and free from dirt, oil, rust and corrosion. Make sure that this does not cause any problem. You must gain access to the wiring at the computer to identify the incoming wires. Some cables can be made at home with the right connectors, So I will show pin-outs for these connectors so you will know which pin gets soldered to where. Step 1: Locate and Disconnect Actuator Connector Every sensor or actuator has a wiring connector.

Connect the probes to either end of the wiring connectors, the meter with show the resistance in the connection. This style printer connector is becoming obsolete. They are typically color coded so they are not inserted into the wrong ports on the computer. There may also be a floppy drive cable. I do not like this because at every Arduino loop, even if I do not change any pin, I got the fan to move.
