Step 5: Fitting the Decoder
The boiler is now still conected to the cab via 3 sets of wires, we shall remove these in a moment. First unscrew the screw holding the water pump in place, and remove the pump.
Now the bottom half of the boilder can be popped off. There are two lugs on either side and by easing the covering plastic (part of the top half of the boiler), outwards, the bottom just drops off. doing one side at a time makes this slightly easier.
You can now remove the wires connecting the cab to the boiler. All 3 simply pull out.
Nearly there, two screws hold the weight to the top half of the boilder, and undoing these the weight drops out, revealing the circuit board. Finally!
Now lets get down to the real stuff, actually physically fitting the decoder! Thanks to the direct socket provided by LGB on the circuit board there really is nothing to it. Shown below is the circuit board and the decoder. (Note: the wires are not needed and are cut off.)
Offer up the decoder to the main circuit board, (it only goes on way) and press down firmly to fix the decoder in place.
In order for the main circuit board to know there is a decoder present, all the 'dip' switches need to be switched to the position shown below as per the manual:
Now, you have probably spent a fair few minutes trying to get into the very innards of the loco it is wise to check that the decoder works before re-assembly. Simply connect the main wire that goes to the rolling chassis, and place your 'half-a-loco' on the track. Below i've checked the light function works, and also gave it a bit of exercise running up and down a 4' length of track:
If your loco refuses to do anything, check the decoder is pushed down firmly, the dip switches are correctly set, and the circuit boards are getting power from the track.
And now all that remains is the reconstruction of the loco. There are no hidden steps in this, a simple reversal of the instructions used to dismantle the loco will result in a MTS ready loco.
Happy Running!
