I recently picked up a postwar 3665 Minuteman Operating Missle Launch car but it won't fire its missle from the control track. The magnet at the bottom of the car engages the electromagnet of the track and the car buzzes and shakes a little but the ramp doesn't raise and the missle won't fire via remote control. If I raise the ramp manually after it reaches a certain height the missle will fire. All of my other operating cars work fine on this control track.
This car is rather difficult to look into and I can't see what is going on inside. Does anyone have any thoughts or suggestions as to what may be wrong with this thing. I apologize for bringing up such a mundane issue but the fact is I rather like this car and would like to get it operational. Thanks in advance for any help or suggestions.
