The solenoid may be sticking in the 'ON' position, never allowing the starter to rest. Listen for a click when you turn the key on. If there is one, the solenoid may be sticking. The solenoid should not click until the pedal is depressed about an inch or so. Also, listen for a click when you release the pedal. If there is no click, the solenoid may be sticking in the ‘ON’ position. This condition can cause lots of problems such as the car running away or excessive heat build up causing melting and burning. This problem is common on E-Z-GO & Melex pre-90 model cars. Click here to see our solenoid selection.
The accelerator micro switch may be out of adjustment causing the solenoid to stay on while the key is in the "on" position. Put the foward and reverse lever in the "neutral" position. Remove the seat and slowly press the accelerator pedal down. Listen for a low, almost inaudible, click when the pedal first moves and another click as it returns to the rest position. If there are not two clicks, especially a first one, the accelerator micro switch is never really shutting down to turn off the car. The adjustment will vary depending on the type of car, but will basically involve adjusting the arm to properly activate and deactivate the micro switch. When the switch is off, there will be no current to the solenoid. When the switch is on, it will allow current to the solenoid. Click here for a variety of micro switches.
