Product Overview: The Kohler RDC2 Power Systems Controller (GM77567-1P) is a generator control module that manages startup, operation, and shutdown functions for standby power systems. It monitors critical parameters including alternator feedback signals and engine rotation during cranking sequences. Commonly used in residential and light commercial Kohler generator sets such as the 14RESA model, it features safety shutdown logic that triggers when proper sensor feedback is not detected within specified timeframes. The controller interfaces with locked rotor sensors and alternator field feedback circuits to ensure safe generator operation.

Common Failures
The Kohler Generator Controller may experience issues such as failing to sense feedback signals from the generator. This can lead to the generator not detecting engine or alternator rotation, causing an automatic shutdown as a safety measure.
Repair Approach
Our technicians perform diagnostic operations by tracing feedback signals and verifying component functionality. Initial steps include applying power to check for component responses and reviewing the wiring diagram to understand signal pathways. Physical disassembly may be necessary to access internal components. In some cases, we may recommend replacement if the controller is determined to be beyond economic repair.
Testing & Quality
Units are tested to determine if the shutdown is a result of normal safety protocols or an actual defect. Testing includes simulating operational conditions to verify the controller functions correctly and does not erroneously shut down the generator.
