What happens when you have a bad wire connection?
Poor connections can rob a system of a significant portion of the power being produced. Stranded wire will compress and flatten out which increases the contact area. This reduces the voltage drop and minimizes heating at the connection.
How to find a bad wire in a car wiring harness?
Cut the outer cover on the wiring harness open at the suspected bad spot. Find the wire being tested by its color. Look for damage to the wire. Turn on the ohm meter and place the dial on the ohms reading.

How to know if a wire is good or bad?
Consider the wire good if the reading is infinite ohms or the same reading as when the test leads were placed together. Remove one test lead from the end of the wire and connect it to each of the other wires one at a time and read the meter for each one. Consider the wire good if the reading is zero when the test lead is connected to another wire.

Poor connections can rob a system of a significant portion of the power being produced. Stranded wire will compress and flatten out which increases the contact area. This reduces the voltage drop and minimizes heating at the connection.
Why do I have three contact areas on my Wire?
When using solid wire in a low voltage system you will notice, at best, that you will have three small contact areas between the solid wire and the device connection when using a typical screw down terminal. This also applies to power distribution blocks or wire nuts where you have only two contact areas, that can cause a heating connection.
