I dont know why my Jato's on board switch wont power the car. The car itself will start with the EZ start but i cant get the darn thing to respond to my Control. When i flip the switch on the car the battery holder( just 4 batteries, not the pack) start to get really hot and at first started smoking and melting. Anyone have any ideas on this?

You probably have a wire pinched under something or your RX is bad or your batteries are in wrong [:-] I bet its something [&:]

Yea maybe, im going to have to check out my wiring cuz i did take it apart to replace the top plate and had to move the wires around. I know its not the batteries, i made sure of that. I replaced the wire switch harness, and the battery holder wire and put in another receiver and it still does the same. But maybe it is a pinch wire or something like that. What is an RX?

That does not sound good LOL. Rx = reciever (the thingy on your RC that the batts and servos plug into, that gets response from the transmitter (or tx)).
