Very rare to have a stator failure, very common to have the original Banner battery totally fail in a short time or the CE rectifier fail, although less so since mounting it to the chassis rather than the vibrating engine. Another possible failure is in the 4 pin Amphenol plug from the stator to the rectifier if it hasn't been fully engaged and burns out but they would have found that when testing the Stator. Oakmere will know what they are doing....... The only stator failures I know of were because of an incorrectly wired rectifier grounding the output and physical damage caused by transmission failure, the stator was the least of the problems.
