This installation documentation is for the Bachmann Light Mountain 4-8-2. This installation uses the WSK-BAC-1 kit, which includes the WOW121-Steam decoder, B-MB1, and 28mm round speaker. This installation was performed by TCS.

See the installation variants of the Bachmann Consolidation 2-8-0 for examples of installations in the different tenders.
Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
When stripping wire, only strip a tiny little bit of the insulation. Strip no more than a 1/32 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire than 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.
