Kohler KD1250-A, KD1350 Industrial Generator Sets Wiring Diagrams (tp7145)

These KD1250-A and KD1350 generator sets usually sit in plants, data centers, or backup rooms and are expected to start under load without drama. This wiring-diagram manual is what I grab when I need to trace control circuits, verify harness repairs, or sort out a miswired retrofit. For example, if the set won’t transfer to load after starting, I use these diagrams to follow the controller outputs through every connector and relay until I find where the signal dies.

Applications & Use Cases

Trace wire routing from the APM603 controller to the alternator, breakers, and sensors to confirm correct connections after repairs or upgrades.
Isolate intermittent faults by checking pin-to-pin continuity against the diagram instead of guessing inside crowded panels.
Verify harness rebuilds or replacements, matching each conductor color and terminal ID so the set behaves like the factory intended.
Plan and test add-ons such as remote start/stop or monitoring, tying into the right points without backfeeding or defeating safeties.
Document field changes, marking up printed diagrams so the next tech understands what was rerouted or bypassed.

FAQ

Q: Can I use this on a tablet at the generator?

A: Yes, it’s practical to zoom in on connector details on a tablet or laptop right at the enclosure.

Q: Is it worth printing parts of this diagram?

A: Many techs print the key sheets they use most, laminate them, and keep them in the generator’s service folder for quick tracing and notes.

Safety Note

Always de-energize and lock out the generator and associated switchgear before opening panels or handling any wiring.
