Check all the grounds. Bet you find corroded metal and the white powder like a battery gets. Between the cable and block or body core support etc etc. There a bunch of them. Sandpaper the wire end to fresh metal and the contact surface also. Once it bolted back together. Put some electronics grease on it. I forget what it is called but radio shack has it. Prevents future corroding. Axle/bearing grease works to.
