Note:This unit may come with one of two rectifiers. 7720-1023 has 14 diodes (40a). 7720-1106 has 8 diodes (avalanche 50a). Replacing one with the other will cause some transmission problems on Case Tractor. The computer will have a bad voltage code and the tranny will automatically cut in Park position.
