Were just purchased a used FP power wheels Kawasaki Ninja 4 wheeler. We have 2 different plug ins to charge the batteries but cannot find where to plug them in.

I suggest you refer to the instructions for the specification.

The first requirement is fitting the charger socket and the next is having the correct polarity.

The type of battery is important and the required charge rate/time is also important. A lead/acid battery should ideally use a constant voltage charger. Ni-cads and similar should ideally use a constant current charger.

The vehicle might have it's own intelligent charging circuitry and just need a power supply but if this is not so then the more sophisticated the charger you buy, the longer life the batteries will have.

you still need help with this?

first of all check for at least 12 volts from the battery and the charger, you can test this using a multimeter

Usually the clicking noise is caused by a crossed wire in the foot pedal.
I would contact the guys at this website http://www.shopjandl.com/kids---baby-ride-on-toys-power-wheels.html
They seem to know how to figure these toys out.
Hope this helps

Most likely a defective battery.  Typically these Power Wheels batteries only last a couple of years.  If yours is under a year old, you might want to contact Fisher Price about a replacement under warranty.

If you battery is old, has continually gone a month or more without being charged, or has been left charging for extended periods of time it could be the battery. But it could also be one of the switches getting dirty. I would suggest going to www.modifiedpowerwheels.com They have all the info you could every want on how to troubleshoot and fix these.
