Thanks everyone for the input.
I have the freedom chip if that makes any difference. I hear that Jim and Mel's do a good job and I am sure they could find the problem but for $50 an hour I can replace a lot of parts. I am pretty sure when the cart doesn't move that the solenoid does not click. It happens so rarely that I'm not ready for it and not paying attention. I have also noticed that some times when I push the pedal it hesitates just a sec and then goes while the pedal is still down. Thanks again for the time.
