I can test a circuit and check if there is powere on switches and

cables but that tis the total knowledge of electronics I have :o(

I was given a childs 12v rideon 4x4 which wasn't working.  If I switch

it on and press the accelerator pedal (swtch) nothing happens.  I have

replaced the battery and can follow the current right through to the

motors but nothing happens.  I have wired the motors directly from the

battery and they work fine.  With such a basic knoweldge of

electronics I don't understand what is wrong?  The only thing that is

slightly confusing is a small Joemex 77 series "thingy" which I

believe acts as a thermal cutout (assuming works for a period of time

as there is no button to reset it)  Can anyone offer any words of

wisdom?
