Battery keeps discharging

My Craftsman lawn mower kills the battery if it sits for a week. The battery is charged up but for some reason it is discharged after sitting idle and the battery is brand new. Any idea what could be causing the short?

start with the battery. How old is it? How many times has it fallen to a zero charge in its life?

then I would put an amp meter on it and see what the parasitic drain is. It could be a bad diode in the charging system, or a bad relay. Need to post a wiring diagram for it or model and serial if anyone is to give much more help than this generic suggestion.

Post the model number of the tractor. Should be on a tag under the seat. And start with 917.

Usual culprit will be the diodes in the rectifier failing open circuit
Pull the connector apart at night in the dark.
If you get a nice big spark you have found the problem.
To confirm it either check the rectifier or just leave it unpluged for the week.
If the battery is fine then replace the rectifier .
The other thing that can drain the battery over a week is the carb solenoid.
Easy way to check that is to touch it first thing in the morning
If it is warm, it is energised .

My mechanic neighbour suggested I pull the key out of the ignition, and that solved the problem, battery was fine the next week. So now I will leave the key out of the lawn mower, I don't think I will buy another ignition switch.

That tells me that you were leaving the switch on.

I had a previous mower doing the same thing. Somehow the switches go bad and allow a connection and battery drain. You can buy a replacement switch and new key for about $30, easy plug and play replacement.

I, too, have a Craftsman rider mower purchased in 2016 that started doing that after 2 or 3 seasons. I purchased a new battery just like you and still had the same problem in a couple of months. (BTW,, I never left the key in the ignition.) I ended up getting a Battery Tender with a quick connect ring connector. Now I just plug it in whenever it's not in use. I never had that problem with the previous Craftsman I had for 12 years.

Craftman riders are now junk. In the first couple of seasons with light use with my current Craftsman, I had to replace a fan belt as well as a tire. Just last year, I had to replace the ignition switch because the reverse mow function broke. Even after 12 years, I never had to replace any of that on my old Craftsman. There's plastic where metal obviously needs to be. It built to have the shortest service life possible. When I have to replace my current Craftsman ( I seriously doubt it will last anywhere close to 12 years) I certainly won't be purchasing another Craftsman, that's for darn sure. Craftsman use to mean true quality but no longer.

One way to check for parasitic drain running down the battery when nothing is on is to take a test light, disconnect the battery ground, connect the test light clip to the ground cable, touch the test light to the ground battery post. If the light comes on something is draining the battery. Try with the key in ignition off and without the key.

Craftsman doesn't make anything. They buy their products from known manufacturers but painted in Craftsman colors. Usually the first 3 digits will tell you whom the manufacturer was.

And at this point is is almost entirely MTD since B-D owns Craftsman and MTD which included Cub Cadet, Bolens, Yard Machine, YardMan, Troybilt, Huskee,, And at one time were also making Toro Consumers products, and Ariens.

You mean like with the Craftsman $100 tile saw I purchased about 15 years ago. There was no display model, I bought one of the two they had a mile from my home, unboxed it, thought the alignment fence looked real cheap and plastic. It broke immediately. I swapped it out for the remaining unit, even greased the fence on this one, it also broke a few cuts in. It was also difficult to add water to the trough and to check on water level. I got my refund.

That night after dinner, we stopped at Home Depot and I bought their $100 tile saw, and it has done well for me; metal fence (first one was off several degrees, took that back to HD with my square to swap that out) plus easier water check and water add. So the HD one was a good purchase.

is there a buzzer or chime that isn't buzzing or chiming any more when the key is left in the ignition?

What I why strange is just leaving a key in the switch causes this. The key is insulated from the electrical system. Strange things do happen but this is very strange.

It is because the consumer wants to buy the cheapest thing out there so even well recognized names have to cheaper products to keep prices lower. I haven't seen this in the commercial line up yet be it will even migrate to that area to. This because they are figuring out how to just get things to last through the warranty period so the customer has to upgrade again keeping the factory running.

I just ran into some Gravely (Ariens) spindles that are nearly impossible to get apart. Mainly due to rust. It doesn't help that the customer crossed threaded the spindle bolts. So it is two new spindles if he want them repaired. Ouch at 250 each OEM. Even the aftermarket ones are 150 each. He said he would run them until complete failure of the spindles. What a shame as the mower is well built otherwise. In this case I cant get new spindle so it a waste of time to try to rebuild them.

And yes it seems no one makes a quality product any more. It like the HFT torques wrenches the first ones I brought lasted five years but now I can't even get one that the scales align properly and the last two fail after a year of use. Junk with a life time warranty is still junk. Personally I depend on my tools working correctly. Heck I got a lot invested in them.

So I trying one of those digital torque adapters. I just don't like the feel, just not same as the clicker type. They are only as accurate as the user pays attention to the beeper. Maybe in time I get use to it but it will do until the new clicker comes in. Hopefully the vendor didn't lie about the new clicker being able to do both left and right torques. (CCW and CW)

Even things like wrenches are not the quality they once were. I even got a couple sets of Vermont American taps and dies where the lazer etched sizes are so fade off it is impossible to read them. Their lifetime warranty is worthless as their are no dealers for them anymore around here.

Yep.Did that last week during the rain.
Got the diamond burrs out with the Dremel (and haven't their quality gone down the toilet ) to remark a pile of taps & dies so I can read them .

That something I should do here to as I do have a carbide tip engraver, now just find the time to do it.

Out to shop I go so I get my daily dose of frustration. OH where where to start today.....Back later if I don't call it quits. I remember last week asking a customer just to run over me.

What about installing a simple shut-off switch like those available at auto parts store?
