If you have a multi-meter, with every thing OFF and battery disconnected, using the resistance function, measure between the two large posts on the solenoid (relay). It should read open or infinite resistance. If it reads any where close to zero ohms the contacts in the solenoid have fused together for some reason. Second test really require two people. Everything connected as it would be normally. With the meter set to VDC touch the + (red) lead to the small post closest to the front of the car (with the wire on the post) and touch the - (black) lead to chassis ground. Have the second person start the car and release the key to the run position. You should see voltage when the switch is in the start position but go away when the switch is moved to the run position. If test one and two are good then it is as 73machman said, hung starter. If the voltage doesn't go away when the switch is moved to the run position it is either faulty wiring or misadjusted/defective switch/lock/rod on the column. Chuck
