This installation of TCS MC2P-SH or TCS DP5 Decoder is for HO Scale Kato GE C44-9W "Dash 9" and was performed by A.G.
Pictures of Kato GE C44-9W "Dash 9" with its shell on prior to the decoder installation.
Grasping the shell at the center top of both sides (being careful not to crush the grills), lift the shell straight up and off of the chassis.
Picture of the locomotive with the shell removed.
Here is the close up picture of the original light board with 8-pin socket (marked in red) Remove the clips (two of them) as shown in the picture above.
Plug in the decoder so that Pin #1 of the decoder lines up with Pin #1 of the socket. Pin #1 will be designated with a "1" or a small arrow/chevron. You can solder additional lighting functions to the pads on the decoder! When you are finished, hold the shell in one hand and the chassis in your other hand. Lining up the front of both pieces, lower the shell onto the chassis, keeping the lower edge of the shell parallel with the chassis. The two pieces will click together.
Important Soldering Tip
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.
You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775
Other solder tips
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.
