Does anyone have a good (better than the "typical" diagram in the haynes manual) wiring diagram of the Headlight circuit with DRL's but no fog lights?

When I turn on the hi-beams the hi-beam indicator turns on but the headlights turn off (i.e. no hi-beams). Since the hi-beam indicator turns on I know that the DRL is getting voltage from the dimmer switch so I'm pretty sure that the dimmer switch is good.

Is there anything else in the circuit between the dimmer switch & the hi beam lamps? It doesn't show anything in the haynes manual drawing.
