Replacing the Top Cover Assembly

To replace the top cover assembly, perform the above procedure in reverse order.

Place the long side of the foam block in between the side of the top case and the side of the

When securing the 2 green ground wires to the control board, make sure the lugs on the

ground wires point toward the battery compartment.
