SOURCE: wrong voltage

Since you don't list the make and model, I'm going to take a guess here. If you are measuring the pads of the output transistors, then the transistors are shorted and need to be replaced. Please post the make and model as well as what you measured so I can confirm the diagnosis and possibly provide any additional parts that should be checked.

Thanks,
Dan

How do i turn on a compaq ps-7231 power supply?


Pin Name Color
Description 1 3.3V Orange +3.3 VDC 2 3.3V Orange +3.3 VDC 3 COM Black Ground 4 5V Red +5 VDC 5 COM Black Ground 6 5V Red +5 VDC 7 COM Black Ground 8 PWR_OK Gray Power Ok is a status signal generated by the power supply to notify the computer that the DC operating voltages are within the ranges required for proper computer operation (+5 VDC when power is Ok) 9 5VSB Purple +5 VDC Standby Voltage (max 10mA, max 2A in ATX 2.2 spec) 10 12V Yellow +12 VDC 11 12V Yellow +12 VDC 12 3.3V Orange +3.3 VDC 13 3.3V Orange +3.3 VDC. ATX V2.3 / EPS12V V2.92 both define that the PSU has to use remote sensing to compensate cable drops on the 3.3V line. Because of this there is an additional brown cable crimped together with the orange cable either to pin 13 (ATX) or pin 1 (EPS12V). 14 -12V Blue -12 VDC 15 COM Black Ground 16 /PS_ON Green Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF. 17 COM Black Ground 18 COM Black Ground 19 COM Black Ground 20 -5V White -5 VDC (this is optional on newer ATX-2 supplies, it is for use with older AT class expansion cards and can be omitted on newer units) 21 +5V Red +5 VDC 22 +5V Red +5 VDC 23 +5V Red +5 VDC 24 COM Black Ground /PSON activated by pressing and releasing the power button while the power supply is in standby mode. Activating /PSON connects the power supply's /PSON input to ground, thereby switching the power supply to full-on condition.

I HAVE A PPI PCX 2200 THAT IS NOT GETTING ANY POWER AT ALL I CHECKED ALL FUSES STILL NO POWER


1.verify connections...Make sure your ground wire is grounded to a location on the body where you will sand the paint away to make good metal to metal contact. 2.with a volt meter check for battery voltage on the red wire of the amp as close to the amp as possible.verify that your remote or trigger wire from the radio (blue wire) id connected to the remote terminal of the amp.. turn on key switch, turn on radio and see if amp powers up. if no then verify 12 vdc at the remote terminal of amp, very 12vdc at red power wire. verify ground. If all this is good i would suspect you have a faulty amp.

No turn signal or 4 way flashers on 2000 flhtcui , all other lights working


The turn signal module gets it's power from the accessory fuse. If the fuse is good, check for 12 volts at the #2 position on the turn signal module (located on the top fork bracket). On the turn signal module the #1 wiring pin position is ground and the #2 wiring pin position is 12 volts dc. If there is no voltage using those two pins, check for resistance between pin #1 and engine ground. If resistance is greater than 1 ohm you have a broken or poor ground wire. If resistance is less than 1 ohm check for 12 vdc on both sides of the accessory fuse. If you have 12 vdc to only one side, replace the fuse. If you have 12 vdc to both sides of the fuse you have a broken wire between the accessory fuse and the turn signal module. If you do not have 12 vdc to the accessory fuse you have a broken wire from the ignition switch and the fuse block.

Won't boot up and not recognised when connected to PC


MANUAL FIRMWARE UPGRADE PROCEDURE:
During the upgrading of the firmware, if you turn off the power of M800, either by manually switching off the power or removal of the battery, the file system of M800 will be damaged, which will lead to booting failure problem. When this happens, you will not be able to turn on M800. Booting failure problem can be easily repaired by “manual firmware upgrade”. The procedures for manual firmware upgrade are as follows:

1. After firmware upgrade, only the blue LED under LCD is on, but LCD display is not turned on, please proceed manual firmware upgrade.
2. Remove the battery.
3. Put the battery back into the player again.
* Notice ! : Do not turn on the power.
4. Connect the player to your PC.
* Notice ! : Do not turn on the power.
5. While pressing the volume down button, power on the player.
6. Now PC should recognize M800 as one of its hard disks.
7. Download the latest firmware file into the root folder of the player.
8. Disconnect the player from your PC.
9. The blue light LED under the LCD display will flicker.
10. Wait for about one minute, blue LED is off. Turn on the player.
The manual firmware upgrade is now completed.
