well i just installed fog lights on my jeep and i figured i must have done something wrong and it was draining the battery so i did the bulb test. no light. unplugged the fog lights and still no light. it was starting perfect all day. i let it sit for 2 hours last night and it started right up. before it was everytime i started it it would turn over real slow. but now it turns over fine. i just don't get this thing!!! It must be a jeep thing cause i do not understand at all!!!!!!

 

so you unplugged the fog lights and now it works fine? if so then leave the fog lights unplugged for three days an see how it works. if after 3 days and no issue with starting occurs then plug the lights back in and see what happens, if the issue returns then you know the culprit. Just curious but is the fog lights a relay setup or just a straight switch?
