is there a continuity test option on multimeter? if so what is it lable as? there a guy told me while ago that if i get 0 ohms on the connection, then it mean the connection is good..but that only let me know that whether my connection is good or bad..what i want to know is how to determine which is the ground point on the pcb...
i try to test a psx pcb, because it is easy to tell which is the positive and ground points..and either grounds or positive, i still get the same 0 ohm on all of them...so i really dont know how to determine the ground on xbox controller pcb...
