How did you check it? multimeter?
Have you checked the ground from the battery to the body in the engine compartment with a multimeter?
Has the vehicle ever been in a serious accident?
Do you have serious body rust?
What you're describing sounds like a poor connection between the battery (-) and the vehicle body. Look for a ground strap in the engine compartment and check it for corrosion or loose connection. Use a multimeter set to 20K or 200K ohms and see if the meter will read close to zero (no resistance)
