IMPORTANT NOTE** Due to a grounding problem, vehicles with the diesel engine often experience converter hub arcing. To correct this situation you MUST clean the starter and starter mounting area and install an external ground strap from the starter mounting bolt to the battery ground bolt on the engine block. If the vehicle has a snow plow you also need a ground strap from the engine block to the vehicle frame.
