226674, Activator Kit, Kohler
Note: The original one-piece activator part # 282772 has been replaced with a new split activator kit. It will look different that yours but does indeed replace # 282772 and is correct.
The service kits are used on the 30--275 kW Fast-Response I generator sets and are designed to replace the standard one-piece activator with a new split activator. Although the function of the activator remains unchanged, the components of the activator are now distributed between the rotating photo transistor board and the SCR (silicon-controlled rectifier) assembly.
The SCR assembly occupies the same position as the old activator and still controls current flow to the
generator field. However, the control circuit for the SCR is now located on the shaft-mounted photo transistor board.
