Gets no power - YOBO Fc Twin Console

again, no computer stated
sad

With the key on, you should get power for the first 3 seconds. Then the computer has to see oil pressure or RPM to know that the engine is running before it will power the pump relay.
The computer grounds the relay to make the connection for pump power. The power is cut if the engine is not running to prevent a fire in a wreck.

If you get no power, it sounds like possibly the power supply may be bad. If you can replace the power supply with known working unit, that would be a good start. If at that point you still get no power, then possibly the motherboard could have gone bad. Even without the ram installed you should get power through the board and when you try to boot you should get a beep or series of beeps. I would start with the power supply tho.

If you mean you measured the power coming from the power supply was only 6 volts from the 12v lead.To be honest its really not worth your time and the parts cost you can get one under $30.00 new.

No power to the printer. 1) Either the power adapter is not connected properly.Remove the power cord from main power outlet and connect it to any other electric outlet.Also at the back of the printer there is a socket where the power got get connected.Remove power wire from there too and reconnect it. 2) If the problem is not solved then there are two possibilities:-- A) The power cord is faulty and needs replacement. B) Or the printer circuit board is got short and it has to be replaced. ------------ In both the cases A as well as B you need to get the fault checked by other spare power adapter or power supply board in printer.At local printer repair shops they have this parts in spare.They will get the fault checked and let you know that which part has to be replaced.Either the power adapter or power supply board.The cost of new power adapter is near to $10 and cost of new power supply board is near to $40. -------------- One more thing i want you to check is.In your printer power adapter there is one three pin power wire is connected.That three pin power wire wire goes from main power outlet to the printer adapter.In some cases that three pin power adapter gets faulty.If that three pin power wire is faulty then the cost of that power wire is just $2.So get that three pin power wire also checked. To see how this three pin power wire looks.See the fig below:---
If this wire is faulty then its not much costly. ----------- This are all the possibilities that you will have to get checked.To get the fault confirmed.Thanks.Helpmech.

Bro it occurred that your system hardware has experience a low power supply wattages that cannot support your entire system hardware wattages requirements. Better change your present power supply into a higher power supply wattages.

Just to make sure:
1. With battery alone in notebook, and no power cable, do you get power?

2. With the battery taken out, and power cable plugged in, you do get power?

IF YES to the above two questions
... and u can get power using the power cable but not using the battery, then your battery is dead and u need a new one.

i suggest you get a volt meter if you don't already one and check to see if your coil is receiving and power. If its getting power but nothing is coming out then you have a bad coil. If its not getting power work your way back toward your battery testing as many points as you can until you get power. The point between power and no power if where your fault is located.

change power supply.

hi,
check if ur input socket is moving , i mean a bit loose. if so then u got problem with ur DC power jack of ur Laptop. u have to get it fixed. if it seems fine then there should be problem with ur power cable of ur adapter. get it checked for short circuit.

cheers :)
