About Kohler 2540332-S Regulator, Rectifier

Kohler 2540332-S REGULATOR, RECTIFIER (20-30AMP) replaces 2540305S, 2540308S, 2540320S, 2540321S, 2540329S. This latest rectifier-regulator, has a ground lug and built-in over-voltage protection that is self-resetting. The over-voltage protection prevents possible damage to other electrical components if an engine is jump-started. This regulator is especially recommended for use on EFI engines, except on Walker mowers where there is insufficient clearance for it to be used. When replacing an earlier regulator, like part number 2540305S, just use the new regulator. To replace an older regulator, whitch has short wire coming out of regulator use kit 24755144S, which includes the new regulator and the necessary conversion pieces. The protective circuit in the new regulator works much like a circuit breaker. If excessive voltage is detected, the protective circuit breaks/opens the charging circuit (B+ output) to prevent the elevated voltage from reaching other components. Excessive voltage can be due to spikes caused by attaching or disconnecting jumper cables, or by loose battery terminal connections. It can also result from a defective battery that is not capable of holding a charge.
