How do I know which battery cable is positive?
The positive terminal is colored red and will be connected to the plus side of the battery. The plus sign will be stamped into the plastic battery casing, it may be difficult to spot at first, but it is there.
Do the colors matter on jumper cables?
5 Answers. No, the colours don’t matter. Using red for positive and black for negative is just a convention. It helps everybody understand the way the circuit is wired, but the current will flow just the same whatever colour the insulation is.
Is yellow jumper cable positive?
Clamp the positive (red or yellow) cable to the positive terminal of the weak battery. Make sure the other end doesn’t touch any part of the car’s engine or body or you could get a dangerous spark. … Clamp the negative cable (black) to the negative terminal of the good battery.
