What Does an Ignition Switch Do?
The ignition switch (key switch or main switch) passes power from the battery to the starter and run circuits. Turning the key to ON powers the instrument panel and control circuits, and turning it to START sends the start signal. Worn contacts or a damaged connector can interrupt that power, so the machine may crank intermittently or not at all.
Signs the Part Needs Replacing
- No crank or intermittent no-crank: the key is turned but the starter does not respond, or responds only sometimes, even though the battery is healthy.
- Starts, then stalls: the run circuit drops out when the key returns from START to ON.
- Dash lights, gauges or work lights flicker or die: electrical power cuts in and out as the key moves.
- Power returns when the key is nudged: a strong sign of worn internal contacts.
- Key hard to turn, stuck or will not return to OFF: a worn lock cylinder or damaged switch body.
These symptoms overlap with a faulty engine control motor, wiring problems or a worn injection pump linkage, so check the whole throttle system before replacing the part.
How to Order and Install the AM879479 Ignition Switch
- Confirm your machine model, engine model and the part number on your existing part before ordering.
- Compare the number of pins, the connector shape and the key type with your old switch before ordering.
- Send a photo of the old part or the nameplate if you are not sure; LIONKITS will confirm fitment for you.
- Check the battery terminals, ground strap, main fuse and starter relay first, and inspect the switch connector for burn marks, loose pins or corrosion.
- Disconnect the battery (ground cable first) before removing the switch, and note or photograph the wire positions and terminal markings so each wire goes back in the same place.
- Fit the new switch, reconnect the wiring and the battery, and test every key position: OFF, ON and START.
