Truck died and I coasted to the shoulder. No lights on dash.Trouble light under hood was out. Ignition switch did nothing.Battery connections OK Walked home and came back with another car,for jump. Before jumping tried to start again. Still no good. Disconnected wiper motor now everything OK. Reconnect and still OK.Afraid to go farther than walking distance of home now.Any ideas??
OK why did you disconnect the wiper motor?
Other than that, I suggest that it may be a bad cable or a fusible link in a battery cable.
