Question: Do I connect the red or black jumper cable first?

Organize the jumper cables First, unravel your jumper cables. Separate them so there is a red and black clamp on each end of the jumper cables. Red is for the positive battery terminal, and black is for the negative terminal.

Does black or red go on first?

Which jumper cables do you connect first red (+) or black (-)?

Can reverse polarity damage electronics?

This can damage the battery and other electrical components. Any battery-powered product you use while its plugged in will be energized through its full circuit and thus a potential source of electrical shock. Reverse polarity can cause PCB damage and even PCB failure, yet the damage can be hard to see.

What happens if you mix up black and white wires?

If you see both sides connected together, it means its a switch loop. The white wire thats connected to the black wire carries power to the switch. And the black wire thats in the same cable carries back that switched power to the outlet.
