Okay it started approximately a week ago I installed a led light bar to the front end of the vehicle, after about three days it started randomly not starting (even after driving awhile) I would get to where I needed to be and when I came back to the car it would not start, and now it got to the point that not even a jump start would work or using a battery charger. We had the alternator tested it is good, then we had the battery tested it was very bad, I bought another battery the correct battery and installed it this morning and still the same problem wont even try to start. If it would jump start for a while and the alternator is good and the new battery installed what else could it be?

Try disconnecting the light bar (put everything back as it was before). Now see if the problem goes away or persists. By the way, which wires [from the vehicle's wiring harness) did you connect the light bar to?

Test starter draw. Make sure the cable to the starter is tight and there is no corrosion on it. With a test light, see if the smaller wire going to the starter gets power when the key is turned to the start position.
