fault

I have an inverter that has blown 3 SMDs i have narrowed it down to either caps or resistors. Is there any way that you guys can help. These components blew when the client ran their inverter off the car battery when the car was running. So I'm guessing over voltage.

Hi all, I’m working on evaluation boards that integrate the Alliance Memory AS5F38G04SND-08LIN QSPI NAND flash device. During our assembly/inspection flow, the boards are subjected to X-ray imaging. Here’s what I’ve observed: Initially, all devices were functional: • Register communication...

Hi i have an playstation 1 power supply that no longer wants to turn on. After a lot of diagnosing and checking parts i figured out that the base of the npn transistor is not getting any power. The transistor is working perfect, i tested it on a different board. But now i dont know what is...

Hi all, I have a Solar LED Light that is not working, and I want to use this to get back into electronics a little. I'm a Control Systems designer, but this level of electrical work still creates a lot of confusion for me. So I am hoping to use this as a learning project. The board is a...

My digital multimeter starts fluctuating while I bring it near to my started bike even if the probes are not connected to any where .I can't read any value during that time.Therefore I cannot check my bike electrical circuit.My multimeter shows correct values when I connect to home ac supply...

I am trying to determine what the secondary voltages would be after the following fault occurred. Basically one phase energized two bushings on a delta-wye transformer. I believe it would be something like this but I am not entirely sure.
