Tips for servicing lighting and Electrical Systems

 

Tech UpdatesTruck-Lite Co., Inc. offers technicians the following tips when servicing lighting and electrical systems:

• Never use a test probe to pierce wire insulation. Wicking action takes place, which causes moisture to travel along the wire strands and corrode critical components. If you have to probe a wiring harness, make sure the puncture is sealed properly.
