Witch wires are positive and negative on the power supply on a ion Pathfinder 2porterbal blue tooth speaker
Difficult to tell without a picture. Quite often the wires (if they are a pair) have a marking line on one of the cores that signifies positive - but sometimes it signifies negative!
If there is a plug fitted (with a barrel connector) the outer part is usually negative, the inner part positive - but again, this isn't always true!
The only SURE way to check is to use a test meter.
