Tach goes to zero when headlight switch is on?

I've only had the headlights working for a couple of years. I have noticed that when I turn on the headlights the tach goes to sleep. After looking at the wiring diagram I can't seem to figure out why this would be. Anyone suggestions appreciated.

It's the earth on the back of the tach.
