Starter 400 amp megafuse blows upon ignition startup. Bench tested starter checks out good and reinstalled. Fuse still blows. Checked positive battery cable to starter for possible grounding, cable checks out good. Fuse only blows when you engage start switch. Please chime in with points to consider...
