Good day istoryans, my cousin is planning to start up a coin operated pc business, then naka palit na sya ug timer and coin slot, ang timer has 2 relays. Timer and coin slot is already working fine, except pag connect sa relay, then nag libog na sya saon to ang brown, black and green wire kanang naa sa timer from relay port, which one daw ang gamiton ato.

Thank you.
