Every multi-meter I have ever owned had a red (positive), and black (negative) lead.

Since your Packard is positive ground the red lead is connected to the chassis/body/battery positive, and the black lead will be touched to either side of the circuit breaker. You should have 6 volts at both poles of the breaker. The plot thickens if you don't have voltage at both poles. No voltage at all (both poles are dead) indicates a problem with the feed into that sub-circuit. Voltage at one pole indicates an open circuit breaker. That is a broken circuit breaker, which is a common situation, but normally they work for a while and then the lights go out, only to come back on when the circuit breaker cools down.

Use your multi-meter directly on your battery to confirm A. The battery voltage you will likely find at the light switch later-on, B.) The meter works, and C.) You've got the positive connected to the positive and the negative connected to the negative.
