Lower voltages for simulation. No information about engine is known or available. Resistor sparkplugs (the lamps) check at 10,000 to 15,000 ohms. Plug wire resistance is 10,000 to 15,000 per foot. The six SPST switches is round distributor cap.
Rather than remove valve covers to sort out firing order, loosen sparkplugs and add a few drops of oil around plug threads. Jog engine slowly. On compression stroke the oil around loosened plug should bubble.
On one compression stroke, open distributor cap to see which terminal the distributor rotor points toward. Connect a cylinder plug wire to fire cylinder under compression. Follow firing order to connect rest of spark plug wiring.
