I have a Dynamark 12hp riding lawn mower that will not charge its battery. I've already changed out the battery for a new one to no avail. What do I do now. I don't see an alternator anywhere. This mower is maybe 7 years old.....Help! I'm getting tired of jumping the mower with my car.

Basically, there is a stator under the flywheel that produces AC current and then it is changed to DC and goes to the battery. Here is a site that has a video on how to check one. http://www.youtube.com/watch?v=9N9EISHD24w God Luck

Would a lawn mower battery work in my truck?
StevenC
My truck battery is dead and the best one we had around was a lawn mower battery.
I've tried it but it wont seen to keep a charge. any ideas?
It would start the truck at times but if it sat over night it wouldn't work in the morning, If looked over everything I can think of but nothing should be pulling power while the truck if off.

You've got two questions- Would a small battery start a big truck? Probably not, since you need a lot of cranking amps to spin the big truck's motor.
Why does it not start in the morning? Though you believe nothing "should" be using your power, it apparently is. Here are two things you can do. Check the age of the battery. There should be a sticker on top with year and month bubbles which will tell you how old the battery is. If it's an 18-month battery that's five years old, you need a battery. If it's a 60-month battery that's a year old, you *might* need a battery, but you have recourse with the vendor of the battery.
Next, clean both battery terminals well, using the wire brush battery cleaners that your local auto parts store sells for $1.99. Then check for battery draw with this simple test. Loosen the negative battery terminal. As you lift the cable on and off the battery terminal, look for a small spark or listen for a small, staticky noise. If you see or hear something, your car is drawing power, even though you think it's not. You can confirm this by leaving the negative terminal off overnight. Then in the morning, put the terminal back on and try to start the car. If it starts with the battery disconnected overnight, you *do* have a draw somewhere. Locating it will be a bit harder, but not impossible. The usual suspects are the radio or alarm, but it could be anything. You can try to find the culprit by putting an ammeter temporarily inline with the battery and terminal, then pulling one fuse at a time out of the fuse box, but this may take awhile. If you see the small draw disappear when you pull a specific fuse, that'll tell you where to look further.
If you just buy a new battery, you may solve the problem temporarily, but batteries don't like to be discharged, so your new battery might take the overnight draw and still have enough cranking amps in the morning, but you may end up with the same situation if you don't diagnose the reason for the problem. Hope you find the solution. ... Good luck!!
