73 es tach 1800 1973

My tach is suddenly very unstable. Will sometimes peg at nearly 7000 rpm when I downshift then settle down to the correct RPM but bounce around 100 rpm or so.

Really strange thing is that it only happens with the headlights on. Turn them off and all is good. Anyone have an idea where I should start trouleshooting?

THanks

Craig
