interior light fuse keeps tripping
I've replaced the fuse for the interior lights (7.5a) more than 4 times within a
6-month period. I'm not sure where the short is. I tested it with a 10a fuse
(yes, i realize that's a no-no) 2 days ago, and it shorted today, indicating that
the interior lights are drawing 10 amps on a line that is rated for lower
amperage.
I thought it may be the phone charger I've been using; however, the cigarette
lighter still charges the phone after the interior light fuse is blown.
Any ideas?
