I found a fuse F4 250V. T1.6A blown. After replace it and turn on the power, my control panel, PSC box and motor doesn't have any power.


Mostly a fuse doesn't fail without a good reason. Sometimes the fault is intermittent and replacing the fuse makes the machine or device work again for a long or short time though it is almost a forlorn hope.

Best practice is to thoroughly check and discover the cause of a failed fuse before replacing it a second time (there usually is a second time).

In your case the reason the fuse failed was probably something else failing in a quite permanent way rather than an intermittent way. It is a nuisance but at least a permanent fault is easier to find than an intermittent one.
The wiring and internal circuitry will need systematic checking both visually and electrically.

Power outlet not working


If your vehicle is still under covered by the factory warranty, take it to the dealer (your vehicle appears to be relatively new). If not, first try your appliance (such as a GPS) in another vehicle or try another appliance that is known to be functioning, to make sure that it's not the appliance that has failed. If you have confirmed that the appliance is functioning but it still will not work in your vehicles power point, I would suspect that the power port is not receiving power because of a blown fuse. Remove the cover for the fuse box (located under the dash) and check the diagram on the back of the lid to locate the fuse that supplies power to the power port. You will have to remove the fuse to see whether or not it has failed. You will know that the fuse has failed if the wire inside the fuse appears to have burned and you see (2) contacts instead of (1) continuous wire loop. If the fuse has failed, replace it with a fuse that has the same amperage as the original. If all of the fuses are good and you know that your appliance is functioning but you still don't have power at the power point, remove the panel that supports the power port and check the connection between the body wiring harness and the power port. If this connection is tight and you still do not have power, disconnect this connection and use an electrical tester to see if you have power from the body wiring harness to the connection itself. If you do not have power at the connection, then there must be a broken wire that will have to be traced and replaced. If you do have power at this connection, then you'll know that the power point is defective (non-serviceable) and will have to be replaced. Unfortunately, this part would only be available from your dealer. Hope this helps.

Why is my 2005 equinox condenser fan not working?


Two possibilities:
1. The switches in the A/C system aren't turning it on, or
2. The fan fails to run when it has power due to blown motor.
To test find the motor to the fan and pull the power plug off it and make a fused jumper wire fused to the fuse size in the system test run the motor directly with power from the battery. IF the fan fails to run it is the fan motor, if it runs than, it is the A/C system controls that failed.

Diagram where fuse is in the polaroid flm-3701


There is a fuse on the power supply board. It is labelled F1. It is a small cylinder near the AC connector. The F1 fuse is 5A 250V. How ever, capacitors are more likely to fail on this television.
The Polaroid FLM3701 has a problem with capacitors failing on the power supply board. If enough caps go bad, you will get no power. Not even a power light. Any capacitor that is swollen is bad.

You most likely have a blown Auxilliary Power Outlet fuse. (Happens all the time) The Auxilliary Power Outlet fuse also powers you Data Link Connector (DLC). If the DLC has no power, the computer scanner will not communicate with the engine computer.
Check Fuse #7 (25 Amp) in the instrument panel fuse block. (See diagram)

Horn and power seats quit working. maxi-fuse extremely hot. pulled it out and re-inserted after it cooled down. fixed the problem temporarily (a day or so). swapped that maxi-fuse with the one above it...


which maxi fuse gets hot ? # fuse , plus amps The power seats uses a 30 amp circuit breaker ,not a fuse . The horn gets power from the same circuit breaker . . Sounds like something is drawing to much current. Do you know how to use a amp meter to test current flow . Disconnect componets till draw goes away ? How to use a wiring diagram to pin point areas in a circuit to test ?
Is there corrosion on the pins where the seat circuit breaker plugs into ? Reach under your seats an see if one of the seat motors is hot .

The left and the right power seat system consist of the following components:
• The seat switches
• The seat relay modules
• The 4 reversible motors:
- The front vertical motor
- The rear vertical motor
- The horizontal motor
- The recline motor
These 4 motors operate independently of each other.
When the entire seat switch is pushed to the FORWARD position, the forward input of the of the seat relay is grounded.
The seat relay module supplies battery positive voltage (B+) with a ground to the horizontal motor, in response to this input. In order to drive the seat forward, the motor runs until the switch is released.
The BACK position works similar to the FORWARD position with the exception that the voltage polarity supplied by the seat relay module is reversed causing the motor to run in the opposite direction. This action drives the seat backward.
These recline switches operate similar but independently:

The seat relay module could be bad , If you don't know how to do automotive electrical circuit testing it mite be a good idea for you to take your vehicle to a qualified repair shop.
Could have diagnostic trouble codes stored as well .

My wii console will not power on. have checked all plugs and everything is connected and outlet has power


HI. the power supply board has failed. There is a fuse(3amps) inside the power supply unit. you will need to remove the cover from the power supply to access this fuse. once inside the power supply, inspect the fuse. if it is truly blown, replace it. if the fuse is not blown, this will confirm a failed power supply unit. it should be replaced in this case...

Microwave ws cooking and I heard a funny sound. Now absolutely nothing..no power..nothing..?? wont even turn on...


Ok, this may have been the in line fuse that has failed or , the high limit capacitor may have failed as well. you will need to remove the cover, if possible, to inspect the power board. the hi limit capacitor is locate in proximity of the power board as well. the in-line fuse is on the board itself, connected to the power cord wires, via solder. if the fuse is in good condition, you will need to replace the high limit capacitor. it has failed.
