Check the fuse(s) first,Make sure the pedal-switch under the cart is connected.Ive seen them unplug from catching something while riding.That will cause the solenoid to not work.If you are getting voltage to 1small stud on the solenoid with the pedal pressed,make sure the other small wire has a good ground circuit,if so,the solenoid is bad.Go to a snow-plow/truck equipment supplier and ask for a 12v continuous-duty solenoid,not a starter-solenoid(they wont last a day on a cart,they are intermittent-duty).Hope this helps.
