Hello, I am new to switch repair but want to get good at it. I have a device now that tells me amps and volts when plugged in. Unfortunately I cannot use it with the OEM switch charger, but in both directions it gives me 0amps 5v. I’ve tested for some shorts but haven’t found any. I just recently found out I can test individual pins when in diode mode by touching ground and the pins but I don’t know what the read outs should be for BQ24. I looked up the data sheet on TI website but I don’t really understand it. Anybody know any good videos for it or have any tips on searching for faults on the motherboard?
