Core Keeper Electricity Troubleshooting Guide

#Direct Answer

When a powered machine does nothing, disconnect the line and test one power source, one wire path, and one machine in that order. Most “no power” problems are a missing connection, a switch left off, or a machine waiting for valid input rather than a broken generator. Prove the short circuit first; only then rebuild the larger automation room.

#The five-minute isolation test

1. Remove the machine from the crowded line or temporarily break the wire beside it.
2. Place one known power source next to it and connect the shortest possible wire run.
3. If a switch is in the design, bypass it for this test. A switch that looks connected can still leave the line open.
4. Insert the machine's required fuel, input item, or recipe material. A powered machine can remain idle when its input is invalid.
5. Watch for one complete operating cycle. Do not reconnect the rest of the base until that cycle succeeds.

If the isolated setup works, the machine is fine. Reconnect one segment at a time until the failure returns; the last segment added is the useful clue.

#Read The Line As Four Separate Jobs

Do not treat “the electricity line” as one thing. A working automation room has four separate jobs:

This split keeps a full room from producing a misleading diagnosis. If the generator powers a nearby test machine, stop inspecting the generator. If the machine completes one cycle but the factory backs up afterward, inspect input, output, or item flow instead of adding more power.

Write the first failed job beside the room before changing anything. “Source failed” and “machine has no valid input” may look identical from across the base, but they require completely different fixes.

#Three failure scenarios worth separating

#Every machine is idle

If several machines stop together, test the source and switch before touching each machine. Bypass the switch for one short cycle. If the line comes alive, the machines were never the real problem; restore the switch and inspect its connection or intended on/off state.

#Only one machine is idle

Keep the shared line intact and test the idle machine by itself. Give it valid input, clear its output slot, and confirm that the recipe or fuel is correct. If it works alone, the fault is probably in the branch or the material feed, not in the generator that is already powering the other stations.

#It stopped after a remodel

Rebuild the shortest source-to-machine path before moving storage, walls, or every station in the room. A one-cycle success on the short path proves that the machine and source still work. Add the old segments back one at a time; the first failed reconnect identifies the section worth repairing.

#The drill runs, but the ore line still looks dead

Treat this as three separate observations instead of calling the whole room “unpowered”:

This prevents a common automation mistake: adding another generator when the actual failure is a conveyor gap or a full destination chest. A working drill cycle is evidence about the power layer only; it is not evidence that the transport layer is complete.

#Use a known-good test machine

If the base contains several different machines, keep one cheap, visible station as a diagnostic reference. Test the source against it before moving a drill, pump, or conveyor-fed machine. The reference station gives you a stable answer to “is electricity present here?” while the target machine may have its own input, fuel, output, or operating rules.

When the reference works:

1. leave the proven source and first wire segment in place
2. test the target machine on a fresh branch
3. run the target for one complete cycle
4. add the conveyor or output device only after the cycle is visible
5. reconnect the old branch last

If the target fails only after the conveyor is added, stop diagnosing electricity. Open the conveyor belt troubleshooting guide and keep the working power branch untouched.

#What to check, in order

#1. Source and switch

Confirm the generator or other source is actually active, then check every switch between it and the machine. A decorative room can hide a switch behind a wall or storage block. Bypass switches only for diagnosis, then restore the intended control once the line is proven.

#2. Wire continuity

Trace the wire tile by tile. Look for a one-tile gap under a floor piece, an accidental corner, or a segment replaced by a non-wire building tile. Do not assume two wire ends touching a machine means the entire upstream route is connected.

#3. Machine conditions

Read the machine's input and output requirements. Smelters, drills, pumps, and other stations may appear dead when they have no valid input, no room for output, or an item placed in the wrong slot. Power is only one part of the recipe.

#4. Range and layout changes

If the line worked before a remodel, inspect the tiles that were moved around the source and machine. Put the source closer for a test, then expand the route gradually. A successful short line tells you the problem is layout distance or an interrupted segment, not the machine itself.

#Reconnect In A Safe Order

Once the short test succeeds, restore the room in the same order every time:

1. reconnect the source to the first junction
2. add one branch or switch
3. run one complete machine cycle
4. add the next branch only if the first cycle still succeeds
5. reconnect storage, conveyors, or extra machines last

Keep a temporary chest or open output tile beside the machine during this pass. That makes it clear whether the machine stopped because power disappeared or because the result had nowhere to land. If the fault returns after adding one branch, leave the working section intact and repair that branch instead of restarting the test from zero.

This order also creates a useful maintenance note: the last confirmed working point, the first failed segment, and the machine condition at the time of failure. A future repair can begin at that boundary instead of rewiring the entire room.

#Stop conditions

Stop troubleshooting when the isolated machine completes a cycle and the fault is narrowed to one reconnect. Do not tear down a working base because a single storage-fed machine is waiting for materials. Stop adding machines to the same line until the first one is reliable; debugging several idle stations at once hides the original failure.

#A Small Maintenance Record Prevents Repeat Failures

After repairing the line, leave three simple notes near the setup:

• the source or switch that controls the branch
• the first machine that proves the line is alive
• the input and output condition that must be true for a cycle

For example: Generator north -> switch off during loading -> Drill A -> output chest south. The note does not need to describe the whole factory. It only needs to tell the next repair where to start and what a successful cycle looks like.

If the room changes later, test that named machine before adding new branches. A one-cycle check after a remodel is cheaper than discovering the break only after every downstream station has stopped.

#Next step

Label the source, switch, and first machine with signs or map markers, then leave a one-tile inspection gap beside the main wire. For a larger factory, use the conveyor belt troubleshooting guide after power is confirmed so item flow and electricity are tested separately.

#Quick diagnosis table

The official 1.3.0.4 hotfix announcement reference supplies the adjacent factual context; the change-one-layer test on this page remains editorial build guidance.

#Keep an Isolation Log

Electricity problems become much faster to solve when each test changes one connection and records the result. Draw the line as four linked points: source, wire path, machine, and output. A working source does not prove that the machine receives power, and a powered machine does not prove that the output has somewhere to go.

Use this order:

1. confirm the generator or source is active
2. test one short wire path with no extra machines attached
3. connect one machine and watch for its actual operating response
4. add the output device only after the first three points are stable
5. reconnect the rest of the factory one segment at a time

Record the first point where the result changes. If the source fails, check fuel or the generator. If the wire path fails, check gaps, direction, and range. If the machine fails while the line is stable, inspect the machine input and operating condition. If only the output fails, check the chest, belt, arm, or destination instead of rebuilding the power line.

Stop when the smallest broken segment is named. A full factory rebuild creates new variables and often hides the original failure. This page should leave you with one connection to repair and one safe order for reconnecting the rest.

#FAQ

#Why does a powered machine remain idle?

Power is only one requirement. Check that the machine has valid input, an available output slot, and any fuel or recipe material it needs. Test the machine alone before reconnecting the larger line.

#How do I find a broken wire?

Use the shortest source-to-machine route, bypass the switch for diagnosis, and reconnect one segment at a time. The last segment added before the machine stops is the best place to inspect.

#Should I rebuild the whole electricity room?

No. Stop once one isolated machine completes a cycle, then repair only the branch that failed. A full rebuild can hide a one-tile gap and create new wiring mistakes.

#Sources And Review Notes

Machine and power terminology was checked against the current Drill and Electricity Generator references.12 The isolation order, stop conditions, and layout advice are independent editorial troubleshooting guidance for common base setups.

The Conveyor Belt reference adds the transport-layer context for testing whether a powered machine is failing or the output line is simply not receiving items.

The Automation reference is useful when the machine is powered but still waiting for a valid input or output condition. The article's branch-isolation order remains editorial troubleshooting advice.
