SOURCE: Husqvarna yth2448 pto switch kills motor/battery will not charge

you may hav a bad alt. problem with the mower dying when you engage the pto is most likley a bad sensor or wire unplugged on the seat sensor.the way it works is if the blades are turning and it dosent sense you being on the seat the mower shuts down.this has been standard on mowers for quite a few years now. it keeps the blades from cutting you up if you fall off the seat while mowing. as for charging i would try cleaning the battery connections and get the battery checked first.

Check your charging system as purplewg recommends. Remove the battery, bring it to full charge and take it to an automotive store or battery shop and have them load test the battery to see if it will hold the full charge. Most places will do this free of charge....if your battery is more than two years old it probably needs to be replaced anyway....Autozone carries a really good tractor type battery for about 35 to 40 bucks that has a lot more amp hours power than most batteries you can buy...if you have to replace the battery get one of these....you'll be glad you did !!! I bought one for my personal mower which sees a LOT of use, and it's been in my mower for three and a half years and going strong...Hope this helps...;-D

Wont start no power to switch


I'm not familiar with your brand and make of lawn tractor but here's a few basics many of them have in common.

Any one of several safety features on newer lawn tractors will prevent it from starting.

Assuming your battery is fully charged, here's a few basic things to check, depending upon your level of skill and motivation:

1. Parking brake: A switch must be engaged when the parking brake is set. Most newer lawn tractors have to have the brake set to allow the starter interlock relay to energize the starter.
2. Blade engagement PTO: The blade PTO switch or lever must be OFF or the tractor starter won't energize.
3. Seat switch: Some (not all) newer lawn tractors won't start if the operator presence seat switch is not closed. (you have to be sitting in the seat or the starter will not be energized.)
4.. Corroded/loose battery terminals or wires. Remove the battery leads and clean the terminals. Check and make certain the battery leads are tight.

You can do some investigative sleuthing by using a multimeter, set in the OHM position, to test switch continuity. Locate and unplug these switches from the wiring harness, one at a time. Insert the meter's test leads into the switch plug's terminals; not the wiring harness. Activate the switch. If your meter shows current pass-through or continuity, the switch is working. If the meter reads OL (for digital meters) or stays at zero, that switch is bad.

If your safety switches are good, you'll have to look deeper.
Some lawn tractors have a fuse panel to protect the electrical circuits and components.
1. If you have a fuse block on your tractor, remove the plastic cover. Most of the fuses in today's tractors are the color coded, plastic cased, automotive type. Remove each fuse and inspect their filaments one at a time. A blown fuse will be easily identified. Replace any blown fuse.
2. The starter interlock relay may be faulty, or have a disconnected/broken wire. Check your wires and terminals. The starter switch itself may be faulty. Use your meter in the OHM setting, put your leads on the starter switch terminals with the switch disconnected and off. Turn on the ignition switch and turn the switch to the start position. If the switch shows current pass-through, the switch is good. If not, replace it.
3. Is your battery discharged? Do you hear a "click" when you try to start your tractor? If you hear a "click" when you turn your key to the start position, and your battery is charged, there's a strong likelihood your starter has malfunctioned and needs to be replaced. (or your engine is seized) If you hear absolutely nothing while trying to crank over the engine, it's a safe bet you're not getting power to the starter because of a safety switch, bad fuse, starter interlock relay, or a broken/disconnected wire somewhere.

Blade engagement lever won't disengage


If this is a manual engagment system all the lever does is to pull a jockey wheel into the back of the belt to tention it thus starting the blades to turn, so either the cable is jammed that pulls the jockey wheel in, or the jockey wheel arm is seized and needs freeing off to allow the jockey to to move to the relaxed position.

The electric clutch needs full power in the battery to stay engaged. I would recommend you check your charging system before replacing the battery. Put a digital volt meter across the + and - terminals of the battery and while running at about 1/2 throttle you should be over 13 volts DC. Probably around 13.5 or so. If not you have a charging problem. Lawn mower batteries I have seen seem to last only 2-3 years. I would also recommend a trickle charger for extended periods of non use. Don't forget the Stabil also.

Hope this helps.

Battery?, wiring??


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.
