Headlight Switch Schematic

does anybody have a schematic for the internal connections on a headlight sw installed on a 1968 Dodge Dart 2 DR H/T?? This makes it very easy to trace wires when sw is in middle position and full-out position.

the reason i would like to know is as follows: I have no headlights in the full-out position and IGN is OFF. I do have BRAKE, TAIL, and Marker. Perhaps a short causing the internal ckt breaker to open (why doesn't it close after 30 seconds). Anyhow will t/s on Thursday. With IGN ON all lights operate including headlights......dah!!!!!!!!!!!

Thx again...great Forum.
