Headlights INOP

[spes96]

First let me caveat this string with: I know next to nothing about electrical issues...

Situation:
Leaving from dinner and I turn my lights on, they flicker and go out. Decide to drive home with the flashers on (only about 3 miles) and get pulled over by the cops for not having my headlights on...citation issued...go to start the car and the lights come on again...drive over to the cop and get the citation reduced to a warning...next day no head lights work.  Parking lights work but when I flip the switch all the way up, parking lights are working but no headlights.  I read though a couple topics here and thought it may be the circuit breaker in the headlight switch but I am not sure how ti check continuity (I have a multimeter), read some more topics and now looks like it may be the dimmer switch. 

How do I verify continuity?  Should all the pins from the switch have power?

How do I eliminate the dimmer switch and the headlamp switch from being the issue.

Many thanks ahead of time,

If your parking lights are fine, my guess is a bad headlight switch.    It sounds like the contacts inside it are worn.

Look in the lower left hand of this diagram for "beam select switch", the dimmer switch on the floor.

Incoming power from headlight switch is lt. green, if that reads +12V DC the headlight switch is supplying power, if not you will need to pull the dash panel to test the switch.
Outgoing power is red or violet wire one is high beam the other low......You might want to check your headlamp harness ground in the area of the battery. Could also be in the bulkhead connector but doubtful you would loose both circuits

Here's the under hood diagram
