Check for a loose negative ground wire where it's bolted to the body. If that's okay, you'll need a test light or voltmeter to locate the break in the circuit. Start with both probes at the battery, then move one probe at a time to the next place in the circuit until you find where the voltage is lost. Leave the head lights turned on so current is trying to flow. That will insure the problem remains in the circuit so it can be found.
