Electrical problem
1995 Lexus ES 350 6 cyl Front Wheel Drive Automatic 169000 miles

Just like the subject. Car won't start in the morning (no crank/turnover). Jump the car. Car starts with no problem. Running smoothly.

Turn on the headlights, engine shuts off.

Repeatable.

I'm guessing a bad bulb or ground, but really don't even know the correct method to hunt down such a problem.

Thanks
