1966 Corvette just replaced Electric Limited wire harness

Customer Question

1966 Corvette just replaced Electric Limited wire harness from head lights underhood and under dash with new oem items. New head light and dimmer switch. Power up system parking lights, brake lights, and turn signal work. When I pull the head light switch to parking position all works fine.
JA: Have you checked the fuses? The dashboard bulbs?
Customer: When I pull headlights to full on headlight position the headlights do not come and the front park lights go off.
JA: Are you fixing your Corvette yourself? What have you tried so far?
Customer: yes using the diagrams provided by Electric Limited's wiring package.
JA: Anything else you want the mechanic to know before I connect you?
Customer: NO. this is the only issue just a the moment.

using your voltmeter check the voltage going into and out of that headlight switch with both the headlight switch off, on park and on headlights to find out what is going on.
