Once you get the problem to appear, either by trying to start the engine or by turning on the head lights, leave whatever you turned on, on so the problem doesn't have a chance to correct itself. I like to leave the head lights turned on so I can watch for a change in brightness when I wiggle wires. Use a test light or voltmeter to measure the voltage at the bolts holding the battery cables to the battery. You must find at least 12.0 volts or the test light must be bright. If not, clean and tighten those connections.
