Check Battery & Connections
Dash Lights are Dim
Check the battery cables – they should be clean and tight. When connections are loose or corroded, it prevents available power flowing to the starter.
Charge your battery – If your battery is completely flat, it will take a couple of hours and will require a battery charging hack.
Jump start mower – This is the fastest solution, but it may not be the long term fix.
Turn on the lights to check for power supply.
If they work - the battery is OK.
If lights are dim - Check battery cables - if OK charge battery.
Dash Lights Don't Work
Check battery state of charge - Very low volts, it's likely the battery is faulty and will not recharge.
Check the main fuse - all mowers will have one, the hard part is finding it.
Use good quality jumpers, if your unsure how use them check out Jump Starting Guide.
When the main fuse blows, all power is lost.
Sometimes they can be hard to find.
Replacing is simple, just pull out the old one and replace.
It's important to replace it with the correct rating, otherwise you can damage the wiring circuit and components.
Check Safety Sensors
For our safety sensors are fitted to the seat, blade engage lever or button, transmission selector, brake pedal and on some models the hood.
Any of these sensors will prevent your mower from starting.
On older manual transmission mowers the gear selector wears and although the selector points to the Neutral position its often still in gear - confirm its in Neutral by pushing it forward or back, it should be easy to push.
This older style Craftsman / Jonsered / Husqvarna blade lever causes lots of no start problems.
The lever spring gets weak and leaves the sensor in the open position which prevents starting.
The quick fix - hold down the lever to start the mower. The complete assembly is available and not too difficult to fit.
Check that all sensors are working, look to see the striker plates are closing the sensors fully.
Check wiring to sensors for chafing and that the connectors are secure and free from corrosion.
Check Control Module
Modules could be fitted anywhere, they are usually fitted inside a hard plastic box about the size of a mobile phone.
Not all mowers will have one fitted, but most will.
Wires come loose, have a helper attempt to start the engine while you wiggle the wiring connectors.
Check also for damage, water or scorch marks on the panel itself.
Check Ignition Switch
Spinning ignition switch's causes damage to the wiring and pins.
Corrosion is another common failure. This usually causes unreliable starting and shut downs.
Try wiggling the wires at the back of the ignition switch while attempting to start the engine, you may need a helper.
Often wires simply come loose, but do check them for corrosion.

- Disconnected wiring
