Re: mower wont start
How old is the battery,unfortunately they do not last very long maybe 2 years average due to non-use,vibration,have it load tested and the charging circuit output tested for output when its running at a high idle speed

First check your battery, make sure the cells are good and no bad cells. If that is good then the issue is under the flywheel. There is a coil under your flywheel that serves as a generator. You can just purchase a 2 am charger with a breaker, that will kick out when battery is charged and hook that up after each use. If you jump a unit or charge a unit with more than 2 amps, you can burn the generator coil out under the flywheel. Also check the magnet under the flywheel. I have seen them come out.
If you jump the starter from battery and it starts, this is what I would do. Use a multimeter and ground black lead from meter to neg post on battery. Take red lead from meter and touch to battery side of solenoid. You should have 12 or more volts. If so, touch red lead from meter to small terminal on solenoid and turn key, you should have 12 or more volts. Last, touch red lead from meter to the other side of solenoid and turn key, You should have 12 or more volts. If first two leads pass the test but the last step fails, you have a bad solenoid. They are usually fairly cheap and easy to replace. Just make sure to disconnect battery before replacing solenoid. If all these pass the test I would replace the keyswitch. I hope this helps you.
it is hard to say exactly what the problem is, but it sounds like the starter, starter solenoid, and or a charging problem.
1. last year I am assuming that the battery was low on charge and once you jumped it, it would start with the key for the rest of the season? if yes your battery should be OK just make sure at the end of the season you disconnect it and store it some where cool but not freezing. if you had to jump it all the time the battery and charging system has problems,(cables)(?).
2. if you have to use the car to jump the mower make sure the mower and car are both 12 volt systems, and the car should not be running.
3. make sure the battery is fully charged and there is no corrosion between the cables and connections.
4. once you do the above you can jump the solenoid to see if the starter is bad, if it moves it should be good, if you have to jump the solenoid make sure the mower is in neutral and the wheels are locked so it cant jump forward.
also make sure all your safety switches are engaged, most mowers have switches on the seat, the blade engageing handle, and breaks.
The lights might have a bad connection at the battery, follow the wires from the lights for fuses and check them, some models have to be started before you can turn the switch back to turn the lights on.
Check the battery voltage with a multimeter. It is possibly low. If so, you can try to charge it. At your own risk, you can attempt to "jump" the mower battery with a car battery. I don't advise this as a common practice. They both are 12 volts, the difference is in the amount of CCA available (Cold Cranking Amps).
How old is the battery? When you get it started put a digital volt meter across the battery terminals and with the throttle about 1/2 open check the voltage. If should be over 13 volts DC if your charging system is working ok. If it is over 13 volts your battery has probably just given up. Lawn mower batteries are only good for 2-3 years. A trickle charger can extend the life if used.
To charge battery, use a trickle charger at 2 amp. Batteries usually only last about 3 years, so if battery is at that age it probably needs replaced. (Replaced my battery with a lawn mower battery that matched the original battery size.) I would try to get a charge on the battery before replacing it. Replacing the battery could be expensive. Battery could also be low on zinc, water, or acid.
Sounds as if battery has internal short. Also have charging system checked. If doing yourself check amperage also. Charging volts and no amps wont work or overcharging. Over charging will ruin a new battery. Also make sure you have clean solid connections between cable ends and battery. Take cables off and clean very good poor contacts will give false readings when checking system.
it sounds like the starter motor is pulling to many amps for the battery to cope with. if its a 12v system it should not pull the battery down to less than 8.5 volts on cranking if it does the starter-motor is defective you can check this with a volt meeter across the batteryterminals and see what it read as you crank the engine. hope this helps
