Magneto Tester - Need an 1156 bulb (and socket if avail)

The #1156 bulb has two terminals. One at the very bottom and the other is the metal case. Solder two wires about two foot long to these terminals or go buy a socket for the bulb and connect the wires accordingly. Connect one wire to the magneto output terminal on the hogshead and ground the wire other to the transmission case or rear of the engine ground. Connect the leads of the analog ac voltmeter on the 10 volt scale to the same two points as the lamp.
Start the car and run on it on battery. Watch the lamp. Is it lit and what is the voltage reading on the ac voltmeter?
