im getting a trifecta of lights as noted in the subject line. when I start my truck these lights don't go out right away and sometimes blink before they go out. this dosent always happen. sometimes it happens after driving awhile, and sometimes it happens when the truck hasn't been driven for hours or sitting over night. im thinking a short or maybe a fuse but cant think what they would even have in common. any help?

 

Possible charging system failure VIA alternator.

Check alternator drive belt for proper tension and operation.

Check alternator for proper out-put.

Check battery terminals for proper fastening/clean terminals.
