This DP2X or DP5 Decoder installation is for the HO Scale Atlas NRE Genset and was performed by ACE.
Important note. You must cut the capacitor wires for this installation. See the last two photos at the bottom for this information. You must cut them in order to get proper speed control and to avoid possible damage to the decoder. We are not sure of the purpose that these capacitors are in the circuit in the first place but they are not needed. If they are not removed the loco will run to fast and there will not be good slow speed control. Also, you need to add a value of one to CV29 to get the loco to operate in the correct direction.
Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use.
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157
When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
