The Ford Barn - View Single Post - Should there be voltage across the high beam and low beam terminal?

The voltage (current) goes through the filament in the bulb to ground and eventually back to the battery. So, there is current (and voltage potential) in the grounds and grounds tend to back feed through other connections. They may or may not be wired correctly, are they working ok?
