Yes the mcor is new, the guy that has it told me there was a sensor under the floor mat.I looked before I took it to him and seen nothing. He may be thinking I have another cart other than a CC but not sure. I will give him chance to look at it but I am not getting my hopes up. I am thinking it is my controller but I am not sure. The batteries tested good, wires good, new mcor, the cart will take off good for several min then slow down to a creep like dead batteries. It can set for 30 min and do a repeat. I have spent 3 time and money in this CC than I ever thought about in my old melex. I am about ready to dump it off the river bridge!!!!!!!!
