Go out at night in the dark, and run it. while looking under the hood, you will be able to see any arching between wires and from the cap. A light water mist will help.

If you are really brave, wet your hand and feel around the cap & wires. If there is arching, you will definately find it this way. (probably break your elbow when you pull your arm away and hit the underside of the hood)
