i think i kind of screwed up.. i "fixed" my battery light problem by pulling the single wire off the alternator (while running) and reconnected it(also while running). the next day my truck is hard to start. once started it ran rough for first minute or so. worked midnight shift went to start it and it started fine. also i havent seen a wait to start light ever but ive only had this truck for 3 weeks. any ideas will be greatly appreciated.
