Light positions on 35 senior eight

Posted by AJS On 2016/8/25 10:27:25

My 1935 senior eight has four light positions. In park the parking bulbs come on. In city I get low beams. In drive I get high beams, but in the third position "passing" I get a high beam on one headlight and low beam on the other. Not wanting to assume anything and not being able to find the information, and I have looked, is this a short in my wiring or is the passing signal of the day.
Thank you
