I have a murray 12.5 riding lawnmower with new battery, wont start or crank over no power at all please help?
Experienced gardeners share their insights in answering this question :
Assuming that you didn’t just aquire it, it’s likely either a faulty solenoid or starter switch. If you just aquired it, it could also be a bad or disconnected seat or brake switch.To test the solenoid, put a voltmeter between the chassis or battery NEG terminal and the small terminal on the solenoid. Does it have 12V when you try to start it? No? you need to test the start switch and the safety (seat and brake) switches. Yes? Check the voltage on the 2 large terminals on the solenoid. One should have 12V all the time, the other should have 12V when you try to start. Does it? Yes? bad or disconnected starter. No? bad solenoid. Testing the safety switches involves testing the resistance (ohms) of the switch. It should toggle between infinite and around 0 ohms as you actuate the switch. If it doesn’t, it’s bad.
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
Check the fuse
The fuse on most riding mowers is connected to the small red wire that connects to the starter solenoid post. Check the fuse and replace it if it`s blown. If you replace the fuse and it continues to blow, you`ll need to find the short in the wiring or component that`s causing the fuse to blow.

The most common reason cars don`t start is a dead or faulty battery. Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire. If something`s wrong with your battery, your car engine won`t turn over.
If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you`re dealing with a battery or an alternator problem.
The blades may be powered by manual force, with wheels mechanically connected to the cutting blades so that when the mower is pushed forward, the blades spin or the machine may have a battery-powered or plug-in electric motor.
If the engine will not crank, you likely have a problem with… Discharged / defective battery or faulty electrical connections. To address these issues, check the battery and charging system for problems. Faulty parts: potentially the safety interlocks, starter motor switch (open circuit) or solenoid.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die
By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.
If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.
With a cranking system, symptoms are divided into one of three possible troubleshooting categories: Click — No-Crank (solenoid clicks but starter doesn`t crank) No-Click — No-Crank (solenoid doesn`t click/starter doesn`t crank) Slow Crank (starter cranks, but engine RPM slow to start vehicle)
It could either be caused by a bad spark plug, bad ignition coil or ignition cable. The wirings could also point to the ignition coil or to no signal from the crankshaft sensor, so you should always diagnose the crankshaft sensor first.
1 Start motor engages but the engine doesn`t turn
The simplest cause of this sort of fault is a loose or corroded electrical connection. If there is a fault with the internal windings of the starter motor, bad brushes, or other electrical faults, the starter motor may lack the torque to crank the engine.
Clip one end of a spark tester to the ignition cable and ground other end to the cylinder head. Spin the flywheel rapidly (at least 350 RPM) and watch for a spark in the tester window. If there`s no spark the coil will need replaced.

Battery?, wiring?? Had a recent problem with blades not engaging. I have had also had a slightly older issue of battery not holding charge so i have to boost or jump start mower. I went out and bought brand new battery and after one usage it would not hold charge and blades will still not engage. Would the issue related to the battery effect the engagement of the blades???
ANSWER : If your Alternator didn’t charging the battery, even though you brand new battery will not last. So there is two possible cause, 1) Your Alternator is not functioning. 2) there is a wiring problem that causing your battery to discharge easily, but you check it after you switch off the key remove the battery negative terminal then touch it back to batt term. and see if there is little blue spark, if does your wiring system got problem. If not, so your Alternator do not charge the battery.

Battery goes dead over night – Toro 42'' Zero Turn Lawn Mower Trailer Package Deal ()
ANSWER : First thing to do is find out if it’s the battery or the mower. Disconnect the battery and leave it overnight. If it’s dead in the morning, you need a new battery. If not, you either have a charging problem (not likely if the battery isn’t dead after using the mower) or you have a current drain.
