Bought the truck a few weeks ago. It had been sitting for a few days. fully charged batt / new Alt. Went to start truck and batt dead. I remembered when I got the truck bulb for dome light was in the glove box (so Mr fix it put it in) I know why it was in their now. Took bulb out charged batt again and no problems. I think the relay is staying energized. The light does stay on for aprox. 60 sec after a close the door but then goes out. Any input would be appreciated. FYI= 03 XL F250 SD Standard cab.(Dome assembly has map lights) ALSO I have searched the forum to no avail for this issue.
