So, I have a 1960 Fleetside that had a bad headlight harness..I wired it up today and the lights stil werent working. I connected it right to the battery and grounde it to the screw on the bezel, but I am thinking that didnt ground well enough. When I turned on the lights, it made a buzzing noise. I re grounded to the battery and the lights now work, but the truck wont start now. The battery is good (I checked) and the radio comes o, lights light and all but the truck just clicks once and wont start? Did I really mess something up? Help!!! I checked the fuses and alls good there too...please help!
