Type of Document: Service and Parts Manual

These Kohler TES and TLS automatic transfer switches usually sit in a mechanical room or electrical closet, quietly moving a load between utility and generator when the power goes out. This parts and service manual helps you match what you see in the cabinet—contactors, control boards, relays, wiring harnesses—to the correct Kohler part numbers before you order. When you’re chasing an intermittent transfer problem or replacing a burned contactor, this book lets you trace each component, verify its configuration, and avoid guessing at “close enough” parts.
