There are 4 things that have to match up.Plug - obviously the plug has to fitPolarity - If the plug fits, this is PROBABLY ok, but the negative/positive must be the same as the originalVoltage - The voltage output should be the same as the original, which will be a few volts higher than the battery. If the voltage output is the same or less than the battery, it won't work. If the voltage is too much higher than the original, it might fry the battery and the charger. Current rating - If the current rating of the replacement charger is less than the original, it might fry the charger. If it is much higher than the original, it MIGHT fry the battery. You can probably go +/- 20%

I would take it to a shop only because the tire has to be on almost perfect so there is no wobble.They have the proper equipment to make sure it is aligned properly.If you are going to go around 40-50 mph alignment is critical.Even jumping moguls and turning alignment is critical.

well you can try and unscrew it and put fresh batterys in

Could be in gear if red light is on

If the battery was melted, that would suggest a bigger problem replacing the battery wont fix - the wiring and switches are probably fried and need servicing/replacing

Make sure the on / off switch is on. If still no start check for good fuel and spark. If fuel was allowed to sit carb could be gummed up.

The battery is probably bad. If a battery is fully discharged it can damage one of the cells in the battery. If you can replace the bad cell then it should charge correctly. Many of these batteries are made to be hard to open up and are hard to repair when they are opened. My best solution is to replace the battery and if that doesn't help then the charger is bad. When the charger is replaced then if both batteries are good then you will have a spare. I hope this helps.
