That's correct, Scott, the switch grounds itself to the dash. tmanfarm, the headlight switch should have to distinct positions, like Scott noted. If it is worn to the point that you can no longer feel the first "click" then you should probably replace the switch. Most everything runs through the light switch so if it is iffy then you can have gremlins.
