-------------------------------------------- One of the scariest things I have ever done was taking apart my Challenger. Whew! Now I can share how to do it with pictures. Pieces! The front engine assembly. Unscrew the teeny tiny little screws on top of the pistons. Unscrew the mount where the front engine connects to the rear section. Then slide the center pipe feed to the slot and you have the front loose (It will be very obvious how how the slot works). The tender. Remove either screw holding it to the engine. Remove the end most two screws on each end. The coupler box too. Then the bottom can be removed. Seen here is the circuit board for the rear light with a feed by fiber optic to the shell. Oh yes... put all the screws back in the same hole you took them from. There are too many different length screws and you would not want to mix them up! On the tender, I put the four screws (the same size) and the coupler box inside the shell. The rear truck on the tender has a feed which comes up into the circuit board. The other two wires feed into the motor.
