Vehicle was running fine same day prior to storm and never had any indication of battery or power issues. Then we had a thunder storm and there was a significant strike close by over head with no actual ground contact and when I went out after the storm my jeep wouldn't start. There was enough power for radio and dash lights but it wouldn't turn over. It would take a boost though, but not keep the charge. Can an overhead lightning burst cause damage to a car battery? I was thinking it was some kind of fluke EMP burst.

  • Welcome to the site @George, what makes you sure there was no ground contact?

  • Might want to check the alternator. Could be the alternator died. Had enough power to get there, but not enough to restart.

Batteries die eventually, often when you least expect them to die. Might be completely casual and unrelated. Try a new battery.

    +1 While electrical damage from lightning strikes is a possibility a battery ought to be the least affected one. As long as radio and dash lights won't indicate an error I would exclude lightning strikes/EMP like stuff..

    Yeah, EMP is Death for solid state electronics, and car batteries surely don't contain solid state electronics.
