Tracker electrical problem

Hey i'm trying to figure out whats wrong with a tracker i am thinking about buying theres no power when you turn the key on the battery is good and the main fuses are ok. So i figure its the ignition switch went out. Is there any other things it could be. Oh and its a early year tracker like 90 91.

Check the battery cables, they may have internal corrosion. Look for swelling just beyond the connectors. Make sure that they are fastened tightly at both ends.

Check the battery for proper level of electrolyte and that it is charged. Use your volt meter to check for power between the battery and the chassis.

Pull out each master fuse and put it back in to make sure it is seated properly.

Check the IGN fuse under the dash. Replace if needed. Note that my '92 kept blowing this fuse until I repaired the ECM.

Good luck.
