Hello everyone My GF-SV50G-BWSM lost the power to the dashboad. Is there anyone could help me to advice me on what should i do get the power to my dashboard Thank you

Hi. Get your owner manual and find fuse box or fuse boxes installed in your car. If you look at legend , one or more fuses will be responsible for your instrument panel in your dash. Replace if they blown. If problem persists and fuses get blown you have a short somewhere. There is a lot of ways to check it out but for now let's check fuses.

Battery is good, alternator is good. when car is off the battery is drained

  1. Follow these steps.
    Remove the negative side battery cable from the negative battery terminal.
  2. Connect the black wire to the com input on the multimeter and the red wire to the 10A or 20A input on the multimeter. the meter needs to be able to read at least a 2 or 3 amps for this test to work. Connecting the red wire to the mA input on the multimeter won't work and could damage the meter.
  3. Attach a multimeter(set the dial on the multimeter to measure Amps as per multimeters instructions) between the negative cable and the negative battery post. Wait a few seconds to several minutes for the car to go into sleep mode - i.e. when you make the contact with the ammeter, the cars computer systems "wake up". After a bit of time they will go back to "sleep".
  4. If the ammeter is reading over 25-50 milliamps, something is using too much battery power.
  5. Go to the fuse panel(s) and remove fuses, one at a time. Pull the main fuses (higher amp ratings)last. Perform the same steps for relays found in the fuse panel. Sometimes relay contacts can fail to release causing a drain. Be sure to observe the ammeter after pulling each fuse or relay.
  6. Watch for the ammeter to drop to acceptable drain. The fuse that reduces the drain is the draw. Consult the owners' manual or service manual to find what circuits are on that fuse.
  7. Check each device (circuit) on that fuse. Stop each lamp, heater, etc. to find the drain.
  8. Repeat steps 1&2 to test your repair. The ammeter will tell you exact numbers.
  9. You can also try unhooking the big wire from your alternator. The alternator can sometimes have a shorted diode that can cause amps to flow through the alternator's power cable and through the shorted diode and into the case and through the bolts and back to the negative battery terminal. This will drain a battery in a hurry.Make sure to read the ammeter before and after unplugging your Alternator

Not gettn fuel replaced pump and fuses still not gettn fuel.

Check your fuse box and make sure the fuse for the fuel pump is working properly. Check all wires make sure there is no grounded wire (multimeter is your friend)

Also check the wires (with the multimeter on your fuel pump side be sure its getting power.

What happens when you put a 250v fuse where a 20 fuse goes in a 1978 chevy truck fuse box?

instead of blowing the fuse it may burn wires and start a fire or fry whatever equipment the fuse controls.

'02 mazda 626 tail lights out

Check your fuse located underneath the drivers side steering wheel. Flip the fuse box cover lid over and you will find a diagram. Pull the taillight fuse out and replace it with the same number fuse. If your taillights still don't work then you will need to replace one of the burned out bulbs. Pull each bulb out and test it with a multimeter for continuity
