Got a question. My neighbor was throwing out a kids 12volt power wheels 4-wheeler the other day, so I went and snagged it out of the trash. My mother in-law has told me that she knows of someone who will rewire these things to run off a regular lawn mower/trolling motor battery. Has anyone ever done this? It looks pretty simple and makes sense. 12 volts is 12 volts no matter if it is coming from a $28 lawn mower battery or a $100 fisher-price specialty battery. My problem is that I don't have the old batteries, so I don't have the wiring harness. I need to cut off the plug that is on the power wheels. There are 4 wires into the plug, and I can't figure out what each is for. Could it be that what I really need is (2) 6 volt batteries. 2 wires for each battery? Maybe I need to go the store and look at a new one. Any help would be greatly appreciated. Thanks. Catslammer out.
