first check the obvious stuff like the Battery terminals. Loosen them and clean the terminals and battery posts, then put them back on and try again.
If that doesn't work, then start checking fuses.
Finally, check the fusible links right next to the battery and starter solenoid.
If it ends up being a fuse or fusible link... you have to try to find out WHAT casued it to burn in the first place... If you just replace it, it may happen again.
