U need a thermal camera with this device to see the shorted component getting hot. What you did is, you already knew or suspected the short component. Its not practical to keep spreading alcohol all over the board to find the shorted component.

NO _ it is not essential to have a Thermal Camera. You have Thermal sensitive fingers God gave you for FREE Use those - When you have located the approximate area of heat source - use Alcohol or Butane to determine the exact the component in the area.

Got one it didn't last pissing time started playing up after a week on a full charge it lasted 5mins had to keep it plugged in then it had an issue with sending output power to a pcb then it started cutting out.... I bought a I2C Short Killer in the end

I think it is not short detector. It should be called voltage injector or prefixed DC power supply. You can inject voltage with any adjustable DC power supply. It doesn't tell you which component is faulty. It just inject DC power and if the defect component become hot and with help of thermal camera or Alcohol you see the defect component. If it does not become hot, you will not find out which component is the faulty one,.

Sir, what happen when the red probe touch the ground, is it damaged the unit? What if we don't know which one is positive on Motherboard, can we just point it?

If red probe touch the ground the light indicator will goes off meaning it goes to safety mode. If you start at low voltage and do it quick it will not damage the unit. Just observe the current reading.

Hi friend...first of all resistor dont cause a short. You cannot use this on resistor. If you put on IC you should identify the pin. Because if you put this on the ground pin then it will read short even there is no short. Start from small voltage to be safe...thanks for your comment.

1. You have to know what is the voltage rail - The reason is that when there are a lower working voltage you apply a higher voltage to - it will destroy the lower-rated voltage components - such as microprocessors and so on. Make sure to know what any particular volt=yage rail you are working on - and what sensitive devices are on that rail before applying an excessive voltage. The tool is dangerous in the hands of the inexperienced and fools - and will damage boards beyond repair if not careful. Make sure to understand the fault-finding process and voltage rails

sir why did you put the voltage to maximum , wont it harm other components in the circuit , think that a short in a circuit could happen because of ocp , ovp, otp to protect the circuit , so if we inject voltage it will damage the other circuits doesnt it , please explain this

The board that i use in this video is operating at 17vdc. The max voltage of VC04 is only 3.8. If we inject voltage the short component will get hot. You should identify it quickly. Injecting the voltage for longer period of time will damage other components. Some are using flir cam after they inject the voltage to find the components that gets hot but flir cam is expensive so in this video i use alcohol. If you will use the VC04 on mobile phone and laptop boards start from the lowest voltage.
