Thanks a lot sir. But i already scan the schematic posted in this thread so far i do have a question.what is the meter would i use in the VOM?voltmeter?(DC or AC?)ohmmeter?(multiplier used) or milliammeter? What is the value of diode? And what push button is being used?
Also,there are only 2 rods being used?some Accumeter uses 4rods. Also the voltage used in ACV. Is it 24ACV? Or 220ACV? What is the current in transformer? 2Amperes? 3amperes? Or 5amperes?
