If they appear OK but problem still persists you can temporarily add your own by using a set of jumper cables from the engine to the battery negative, and from the frame to battery negative. This will prove that there is (or isn't) a ground issue.

Good Luck

This.

It sounds like you have a grounding problem or a short somewhere to me...
