Now you are describing 2 different problems... If you have nothing I doubt the battery is dead but would check for a safety switch problem. If it clicks or turns over slowly then we need to be looking at a bad connection or other issues... Please describe your problem better to let us help you solve it

Hi, if your battery wont charge you will need to replace it and when you do you need to check that the mower is charging by checking the battery voltage with a multimeter while the mower is running. It should be around 14 volts. Regards Phil.

My Craftsman 16 hp and 42 battery not charging is it normal?


get mower started and check the charging voltage at battery. it should be at least 13.5 at battery.check cables to battery and the inline charging fuse, its located somewhere in charging system.if its charging, but battery is still dead. it could be a bad battery. or alternator. . Examine the lawn mower electrical system by starting the lawn mower up, and then removing the battery. If the lawn mower turns off after the battery is disconnected, the lawn mower electrical system is the culprit.
its a good possibility that the battery is bad if it has been in use for 4-5 years.
check the fuses first. good-day !

The battery in my JD lawn tractor was dead; it started and mowed several times with a jump start but eventually only the tractor would run while the mower would not engage. With a new battery installed,...


I suspect that the alternator/generator has gone bad, preventing the battery from chargine, or generating enough voltage to keep the electric pto on your mower engaged.

I think that it is located on the engine beneath the flywheel.

I hope this helps you.

Dead battery


The blade clutch is electric. A bad battery might be interfering with the clutches engagement. You should make sure you have good contacts on the battery at both ends. Replace any battery cables that are excessively corroded. If the battery had removeable caps for filling you might want to check the electrolyte levels and top them off with some distilled water. You can also jump start your mower and check the voltage while running with the blade off. If you dont see voltage going up while the engine is running you probably have battery and charging system issues. The battery should have at least 12 volts with the mower off and 13-15 volts with the engine on.

A bad charging system would require repairs on the motor and should be handled by a local repair shop. At least you can rule out the diy stuff first though right?

Good luck and be caeful. Wear eye protection whenever working around batteries with jumper cables. Weak batteries give off explosive gases. Always connect the cables to the bad battery first and then the good battery to avoid sparking near the bad battery.

Tractor wont start unless I jump it


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.

I hope this helps.

Batt dead jump start does not seem to charge


Sounds like a dead or shorted cell battery. Charging system is probably working but is showing overcharge since it is trying to charge a brick. Replace the battery and all should be well.
