My 93 honda accord has developed an issue. I was sitting in a parking lot waiting on someone and turned my car off, 10 min later when i went to start it it was dead, completely... When i jumped it it started and ran fine for a week, then same problem, only now, while im driving. When i jumped it it ran fine for about 4 days then it was dead again, same thing, dies while im driving it. Now it seems like every so many miles it dies and has to be jumped. Ive replaced alternator, main relay, and wiring to ignition switch and ive had the battery tested. What else could it be??? I'm beginning to think it has something to do with my headlights. Could my headlight being on cause this?

 

Not unless they stay on when the car is off.

Sounds like a parasitic draw. To test for parasitic draw: With the car OFF, disconnect the negative battery cable from the battery. Then clip a test light to the cable and touch the probe to the negative battery post. If the test light comes on you have a parasitic draw.

If you do have parasitic draw leave the test light connected (cable and post) and pull fuses one by one to determine problem circuit.
