Help with dash lights

[Jim_PA]

Prior to installing a new headlight switch, the only lights that worked were my high beam indicator, and my turn signals/flashers.

After installing the new headlight switch, my interior light started working, and the turn signals still flashed when the headlights were off.

Now when I turn on the headlights, and use the dimmer, the fuel gauge has lights, and the 2 turn signal lights and the high beam indicator light up, and actually get brighter/dimmer when I turn the knob. The speedometer lights don't come on... either that, or they are burned out. When I turn on the turn signal, or hit the high beams, the respective light just flickers out.

If I turn the dimmer all the way down so the dash lights are off (but the headlights are still on... the dimmer and turn signal indicators work normally again.

Any ideas?
