Are the red and black wires coming out of trailer lights supposed to be shorted? I have a continuation tester. It beeps when the two probes are connected (aka touching) in continuation mode. I tested the red and black wires coming out of my trailer lights. The beep goes off which would indicate that there is a continuation (aka short) of some sort between the red and the black wires. Is this normal behavior or are my lights fried?
