This installation is for N-Scale Broadway Limited Imports EMD E8A, uses TCS M1P-SH decoder, and was performed by A.G.
The two upper pictures show the beautiful shell of the EMD E8A.
Unscrew the Phillips screw (circled in red) that holds the coupler and the chassis together and remove the coupler.
Gently remove the locomotive's shell starting from the cabin end.This picture shows the locomotive's chassis with its shell taken off and the original light board.
Bravo for Broadway Limited!!!! The 8 pin NMRA socket is installed on the original light board which means many different decoders can be used. We picked TCS M1P-SH as it is one of the smallest decoders we offer and it fits perfectly underneath the shell. Remove the two "dummy plugs" that the locomotive comes with as shown in the picture above.
Here is the picture of the locomotive chassis with M1P-SH installed.
Here is the close up of TCS M1P-SH decoder installation. Place the shell back, reattach the coupler and the engine is ready to go!
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.
