Hello everyone.
I have just built a small solar charger that charges a 6V battery. This in turn goes through a very simple op-amp circuit to check low voltage (in parallel) and then through a 5V voltage regulatorto a USB plug.
My problem, is that at the input, if I use my multimeter to check for short circuit/connectivity, if i use one polarity, it looks fine, but when i inverse the polarity of the multimeter leads, it appears short-circuited.
Could anyone suggest anything please?
thanks,
Hlias.
