Hello everyone
me and my friend are working on a mk160 circuit boar. it's a remote controll through cellular phone. the board is all but done but we're stuck on 2 capacitors and a ldr.
there's no markings on the capacitors or the ldr to determine polarity. How can I do this without testing equipement?
they're 100nf capacitors and there's "104." written across it wich could be used to determine + and -
Can anyone help with this?
oh yeah, the negative pole always needs to be pointed towards the large conductive path that covers most of the pcb right?
Thanks
