My 1987 f250 has an electrical problem, i can jumpstart it and it will start right up and run fine except for the batery meter drops whenever i turn anything on like my blinker, radio, headlights ect. after i have started the truck and let it run i will shut it off and go to start it right after and it wont start but this doesnt happen all the time simtime it will start for a week before i have to jump it again i have replaiced the starter, alternator, solenoid, ampage regulator, ignition, positive and negotive battery cables, the battery, i have cleaned the grounds, i did a light test to check for draws and the light came on we found the fuse and took it out and that didnt fix it when i take off the positive battery cable to let it run off of the alternator it still runs fine and i dont know what else to do
