Faulty power supply

DTC P1682 Ignition 1 Switch Circuit 2
The ignition 1 voltage of the ignition main relay is more than 3 volts different than the ignition 1 voltage of
the powertrain relay for more than 2 seconds.

There are 2 ignition 1 voltage circuits supplied to the engine control module (ECM). The first ignition 1
voltage circuit is provided by the powertrain relay through a fuse. This ignition 1 voltage circuit supplies
power to all the internal ECM circuits associated with the throttle actuator control (TAC) operation. The
ignition main relay provides the second ignition 1 voltage circuit to the ECM through a fuse. This ignition
1 voltage provides power to other internal ECM circuits, except those associated with TAC operation.
The ECM continuously monitors the voltage level difference between the 2 circuits.

Confirm there is power in the wall socket and that the mains cable of the Acoustimass Module is OK,then check if the Boselink audio cable is inserted firmly into the zone1 output of the Media Center and the input of the Acoustimass Module.Turn the Acoustimass Module upside down and power the system,if led indicator blinks orange,the Acoustimass Module is faulty but if it blinks an intermittent but regular green light,the fault could be from the audio cable or Media Center.Only a qualified Bose Technician can handle this kind of fault

All fuses supply power to the four wheel drive control module , the control module supplies power to mode select switch . The 4WD control module accomplishes shifts by interpreting inputs from the following:

• mode select switch (MSS)
• vehicle speed signal
• encoder plate position
• brake pedal switch
• digital transmission range (TR) sensor
• ignition switch
• transfer case shift motor
• Based on these inputs, the 4WD control module controls the shifts into 2WD, 4WD HIGH or 4WD LOW with the following outputs:
  
  • shift motor (clockwise)
  • shift motor (counterclockwise)
• Fuses
• Battery junction box (BJB) fuse:
  • 1 (50A)
  • 3 (50A)
  • 13 (20A)
  • 30 (10A)
• Central junction box (CJB) fuse:
• 28 (7.5A) (manual transmission)
• 10 (7.5A)
• 11 (7.5A)
• 5 (15A)
• If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu.

The input to your treadmill is about 120 volts Ac. The output from the board will be about 30 Ac. Almost nothing on there will be measured in DC. Your particular issue is your motor controller. It needs to be replaced.

No power and power LED does not light up, this indicates either the mains power is off or you have a faulty power lead. Test the mains socket and the mains power lead.
If these are OK then the fault most likely a faulty switch mode power supply. Remove the switch mode power supply and get it tested at your friendly computer repair shop OR borrow a power supply and insert it into your PC to see if it now boots up.
If it boots up the replace the power supply with a new switch mode power supply with the same total wattage or higher wattage.

You need to check that the power supply is working. To this safely you will need a voltage meter. You can buy multimeters from most electrical or electronics stores such as maplin. On the power supply there is a diagram showing the power pins and the voltage output. You should be able to read 12VDC across the pins when the mains power is connected. If there is no 12VDC then check the fuse in the plug. This is a 3A fuse and it can be easily removed from the plug with a suitable flat blade screwdriver. Use your multimeter on resistance (Ohms) setting or on continuity (bleeper) setting and test across the two ends of the fuse. If the resistance is nearly zero or the multimeter bleeps then the fuse is OK. If the fuse is Ok and you mains socket has power but there is no power output then the power supply is faulty. If there is 12VDC out of the power supply then the Wii is faulty. If it is under warranty then take it back to the store. If it is out of warranty then get someone to fix it (if possible).

hi,
check the mains chord, also check the power in the wall socket to which the projector is connected. if all these ok then,may be its power supply side have some problem. its an smps power supply. just check its input fuse on the smps. if it fond faulty the do not replace it suddenly. check is there is any thing faulty on the smps board. because the fuse will blow off only if there is any problem in smps. check it first before inserting fuse.
ok

Hello bad minton 2 hi, check the common things first.
1. power cable, make sure its good. 2. AC mains outlet. 3. Loose AC port connection of the power cable. 4. Power switch.
If all is OK. problem is the main power supply board. Now you may need to open the back cover. Caution: this should be done by a pro. 1. Check the fuse for open. if open proceed if not go to 3. 2. Check now for shorts like diodes and transistors. 3. Check for voltage outputs. you need a manual or diagram for this. 4. To check for voltage readings, you need a multitester for this: 4a. check the ac 110/220 volts entering the power supply module. check the cable. 4b. check the dc output from the filter capacitor. no output, check the fuse or fusing resistor. diodes 4c. now the voltages at the VCC line after the regulator. If no readings problem with the switching circuit. Note this is not as simple as you think. have a tech guy do the work if you cant find the problem.

When everything does'nt work the problem is usually esier to solve..it implies a faulty power source.

The fault may lie internal or external to machine. To rule out external machine fault try to use some other appliance on the same plug point if it works we know the probles lies within the machine.

If the problem lies within the machine, unplug power source and open the machine.determine where the power cable terminates within the machine. We are now going to check for breakages in the powe cable (that connect the machine to power source) You will require a multimeter. With the multimeter placed on continuity mode check for continuity between the plug point and internal terminating point, you need to perform the continuity test for both live and neutral in unplugged mode.

Next if the fault is ruled out in the cable the fault most certainly lies in the SMPS to check this we need to take a few precautions and carefully observe the power input and output points on the washing machines SMPS (Switch Mode PowerSupply) older machines use a transformer but it all boils down to correctly determining the input and output terminals.

Now with the multimeter in Volt meter mode(AC), carfully power the machine through AC Mains, ensure that the ground and machine are not damp (wet) without having physical contact with the machine you need to test the voltage across the input terminals (this should read around 110 to 220 (AC)Volts depending on the standards of your country) then check the voltage off the input terminals this should read between 20 and 80 Volts DC.

In most cases with your typical problem mentioned you will fail to receive an output voltage at this stage and can conclude that the SMPS is faulty.

If the SMPS is faulty you'd simply have to change it , in some cases though these have detachable fuses which blow off. In the lastter case you can try a fuse rep[placement.
This should solve your problem.

Hi ,The 9105 PTU Takes the ships mains from the PCT 9106 PCB make sure you have the supply form the PCT board ready which is a protection circuit ,should you have an overload from the modulator pcb then the pct board shall inhibit the supply to the ptu 9105 ,so here is what you have to do ,disconnect the HV 330 volt going to the modulator pcb and then switch supply on ,ensure your fuses are all fine .fond [email protected]
