Hey everyone, recently, my 1990 f350 has had trouble starting on occasion, what usually happens is that it will start normal most of the time, but occasionally, when I trun the key it sounds like the battery is dead, I'll try turning it again and it is usally successful, but sometimes takes a few tries. Does anyone have an idea of what the problem is? Thanks in advance.

 

Check your battery cables and connections. replace the cables if you see any corrosion and clean up any on the connectors. Check the frame to block ground cable also.
