Abstract
A technique for electrically isolating a vehicle body carrier from a vehicle body during an electrode position coating process, and a vehicle body carrier that has been so electrically isolated. Points of potential charge transfer to the vehicle body carrier are preferably isolated. Electric current is routed to a vehicle body on the carrier by means of a conductor cable that preferably runs through the hollow interior of at least one vehicle carrier support member to a conductive vehicle body support component, thereby electrically charging the vehicle body. The retention component and other conductive points of contact between the vehicle body and the vehicle body carrier are isolated to prevent charge transfer. In this manner, the vehicle body carrier will not attract e-coat during the electrode position process and, therefore, will not experience a buildup of e-coat material.
